Ama-disks e-SSD ayinto entsha ngokwesivinini, lezi zinto ziyizingcezu ezibalulekile kuma-PC nakuma-laptops esizukulwane esisha. Le divayisi engenazo izingxenye ezihambayo isiphenduke umkhuba emhlabeni wonke; zishibhile ngempela futhi zihlala isikhathi eside. Kukho konke lokhu okuthunyelwe uzokwazi konke ngokusebenza kwayo kanye nama-SSD amahle kakhulu akhona namuhla.
Yini idiski ye-SSD?
Idiski eyaziwayo ye-SSD ubuchwepheshe besitoreji sakamuva. Njengoba igama liphakamisa, i-SSD, ngokungafani ne-hard drive yendabuko, ayinazo izingxenye ezihambayo. Esikhundleni salokho, isebenzisa inkumbulo ye-NAND flash. Inkumbulo eningi ye-NAND (Negative-AND) ene-SSD, iba namandla okugcina ngaphezulu. Ubuchwepheshe besimanje buvumela ama-SSD ukuba abe nama-chips amaningi we-NAND kunanini ngaphambili, okusho ukuthi ama-SSD angaba namandla afana nama-hdds.
Ngamanani aphansi okwehluleka nempilo engahle ibe yinde, abantu abaningi kulezi zinsuku bakhetha ama-solid state drives (SSDs) ngaphezulu kwama-hard drive. Kunoma ngubani osemakethe yekhompyutha entsha noma i-SSD, kunezinto ezimbalwa okufanele wazi ngaphambi kokuchitha imali eningi, kufanele uzigcine engqondweni.Yiziphi izinzuzo zayo futhi yini ongayithola ngokuthenga kwakho?
Indima yama-SSD amahle kakhulu
Ukushayela kwe-SS kusebenza ngokuhlukile kune-hard drive yendabuko (HDD), ngoba azikho izingxenye ezihambayo. Ngenkathi ama-hard drive esebenzisa ujikeleza wediski wediski ukuthola imininingwane, i-WEB SYSTEM idlulisa imininingwane kuma-chip memory memory, njenge-smartphone, i-USB drive, noma i-slim tablet. Njengoba idrayivu akudingeki ilinde noma isiphi isitsha ukuze iphendukele lapho kunedatha khona, zonke izinkumbulo zememori zifinyeleleka ngasikhathi sinye. Lokhu kwenza kube lula kakhulu kubasebenzisi ukuthola imininingwane yabo ngejubane elikhulu.
Ama-SSD akhiwe ngokuhlukile ngenxa yalokhu futhi ayatholakala ngezinhlobonhlobo nobukhulu obuhlukahlukene, kepha ayabiza ukukhiqiza. Ngisho nokwehla kwamanani zisengaphezu kokuphindwe kabili izindleko zamadrayivu anzima ngendlela efanayo ngo-2020. Lokhu kuyiqiniso ikakhulukazi kuma-SSD asheshayo futhi amakhulu, njengoba isikhathi siqhubeka kulezi zengezo ziba zintsha futhi zinikeza izinzuzo ezinkulu.
I-hard drive ejikelezayo ifunda futhi ibhale idatha ngomazibuthe, okungenye yemidiya yakudala yokugcina esetshenziswa ngokuqhubekayo. Amandla kazibuthe, noma kunjalo, angaholela ekwehlulekeni kwemishini. I-SSD, ngokuphambene, ifunda futhi ibhale idatha ku-substrate yamakhompiyutha we-flash memory axhunyiwe, enziwe nge-silicon. Abakhi bakha amayunithi we-ELECTRICAL SYSTEM ngokufaka ama-chips kugridi ukufeza ukuqina okuhlukahlukene.
I-ssd enhle kakhulu igweme ukuguquguquka
Ukugwema ukuguquguquka, abakhiqizi be-SSD baklama amadivayisi anama-transistor esango entantayo ukubamba imali kagesi. Lokhu kuvumela i-SSD ukuthi igcine idatha egciniwe noma ingaxhunyiwe kumthombo wamandla. I-FGR ngayinye iqukethe idatha eyodwa, ekhethelwe iseli elikhokhisiwe noma uma iseli lingenayo imali kagesi.
Uma ingekho i-solid state drive, i-SSD iyindlela yokugcina esebenzisa imemori engeyona eyokuguquguquka njengendlela yokugcina nokufinyelela kudatha. Ngokungafani ne-hard drive, i-SSD ayinazo izingxenye ezihambayo, iyinike izinzuzo ezifana nesikhathi sokufinyelela ngokushesha, ukusebenza ngokuthula, ukuthembeka okuphezulu nokusetshenziswa kwamandla okuphansi.
Ibhulokhi ngalinye ledatha liyatholakala ngejubane elingaguquguquki. Noma kunjalo, ama-SSD avunyelwe kuphela ukubhala kumabhulokhi angenalutho. Enye indlela ephumelelayo kule nkinga, ama-SSDs angasebenzisa ukuhlinzekela, ukulinganisa ukugqoka, noma izindlela zokuqoqa udoti. Kepha noma kunjalo, ukusebenza kwe-SSD kungancipha ngokuhamba kwesikhathi. Amabhalansi wokushaja wokugqoka gqoka amaseli we-flash, ngenkathi ukuqoqwa kukadoti kususa amafayela amadala ngemuva kokusebenza.
Isivinini
Ama-SSDs ngokwesiko asebenzise ukuxhumana kwe-SATA, okunesilinganiso sokudlulisa esiphezulu esingu-750MB ngomzuzwana. Izizukulwane ezintsha zamayunithi okusakaza nge-inthanethi zixhuma ekuxhumaneni kwe-PCIe kwebhodi yomama, zinikela ngejubane elifinyelela ku-1,5GB ngomzuzwana. Izinga lokuxhuma le-PCIe M.2, elethwe ngo-2014, linikela ngokudlula okuphelele kwezwe langempela okungaba ngu-4 GB / s.
Ama-HDD amahle kakhulu yiminyaka elula ukusuka kuma-hard drive. Ziyashesha kakhulu, zithatha amandla amancane, futhi ziqinile kunabalingani bazo bendabuko nabadala. Eqinisweni, ukuba nohlobo oluthile lokwehluleka kokusebenza ngamashayela asebekhulile kuvame kakhulu, okwenza ukushintshela ku-SSD kube ngcono kakhulu okudingekayo.
Njengoba ama-SSD abekhona isikhashana, ukuthola i-SSD ehamba phambili akubizi cishe njengoba bekujwayele futhi ukuthuthukela kokukodwa akuyona eyabasebenzisi abasindayo kuphela. Noma ungenawo ama-PC amahle kakhulu, usengasizakala ngejubane i-SSD ekunika lona. Eqinisweni, amakhompiyutha nama-laptops amahle kakhulu asevele eza ngokujwayelekile ngama-SSD, hhayi nje ngenxa yejubane kepha futhi nangenxa yesici sabo esincane.
Isitoreji sedatha
Ukushayela kwe-SS kuncike kumeshini wamaseli kagesi ku-NAND ukugcina idatha, futhi kufaka phakathi iprosesa edidiyelwe eyaziwa ngokuthi isilawuli esisebenzisa ikhodi esezingeni le-firmware ukusiza idrayivu isebenze futhi ibhlose imidiya kukhompiyutha eyisingathi ngebhasi le-interface. Ngaphakathi kwesikhala sememori uqobo, amaseli weseli ahlukaniswe ngamakhasi, lapho kugcinwa khona idatha, namabhulokhi, angamaqembu wamakhasi. Amayunithi amasha we-DES amasha avela efektri agcwaliswa ngamabhulokhi aphelele wamakhasi enkumbulo engasetshenziswanga.
Ama-SSD abhala idatha entsha kuphela kumakhasi angenalutho ngaphakathi kwalawa mabhulokhi. Njengoba ungacabanga, njengoba ukubhala okusha nedatha kugcinwa kudrayivu, lokhu kusho ukuthi ekugcineni amakhasi amasha angenalutho angenalutho aphelile. Uma lokhu kwenzeka, kudinga ukuphathwa okuhlakaniphile kwamakhasi angenalutho ngaphakathi kwamabhulokhi yunithi. Lapho idrayivu ithola ukuthi amakhasi amaningi ngaphakathi kwebhulokhi awasetshenziswa, isilawuli se-SSD senza amakhasi alelo bhulokhi kwimemori, sisule lonke ibhulokhi, bese sibhala idatha ibhlokhi, singanaki amakhasi angasetshenziswanga bese siwashiya engenalutho .
Kungakho ukushayela kwe-SSD kushesha ngendlela emangalisayo lapho iningi lingenalutho, kepha livame ukukhula kancane njengoba liguga, kungenxa yokuthi le nqubo yokuthola ibhulokhi enendawo engasetshenziswanga, ukuyenza, ukuyisula, ukuyibhala kabusha, bese ukubhala idatha entsha kufanele zenzeka njalo lapho idatha entsha idinga ukuphinda ibhalwe kabusha kudrayivu endala. Kepha empeleni, lokhu kwehliswa kokusebenza kuthatha iminyaka yokusetshenziswa kakhulu kwedrayivu.
Ukuvela kwama-SSD amahle kakhulu
Ukugcinwa kwamabhizinisi kufike ibanga elide emlandweni omfishane wekhompyutha. Ama-Solid State Drives (ama-SSD) adlale indima ebalulekile ekuguqukeni kwalesi sitoreji. Ngakho-ke lezo zinguquko zenze ini ngokuya ngezakhi, izinzuzo nezinhlelo zokusebenza? Ukuhlola umlando wama-SSD kusiza ukudala isithombe salokho ikusasa elizokuphatha.
I-SSD yokuqala
Ukusetshenziswa kwememori ye-flash yesitoreji sesikhathi eside bekulokhu kwenzeka kusukela ngawo-1950, kepha lezo zixazululo zazivame ukwenziwa kubasebenzisi bamagama abakhulu noma kumakhompyutha amancane futhi zazidinga izipele zebhethri ukugcina okuqukethwe kwememori lapho idivayisi ingekho. Inikwa amandla ngumgcini, njengoba lezo zixazululo wasebenzisa inkumbulo eguquguqukayo.
Ama-SSD ezentengiselwano afana nalawa atholakalayo namuhla enza ukungena kwawo emakethe kokuqala ngawo-1990, ngo-1991, i-20MB SSD yathengiswa ngo- $ 1,000. Ngokusobala, amanani ehle kusukela ngaleso sikhathi, futhi ukusebenza kuthuthukile njengoba izindlela ezahlukahlukene zebhasi le-PC zikwenze kwaba nokwenzeka ukuthi amazinga okudluliswa kwedatha adlule kakhulu amanani ajwayelekile imithombo yezindaba ejikelezayo engagcwalisa.
Ukushayela kwe-Solid State (SD) kwavela ngawo-1950 ngobuchwepheshe obufanayo obufanayo: iMagnetic Core Memory neCard Capacitor Read Store kuphela (CCROS). Lezi zingxenye zememori ezisizayo (njengoba zazibizwa abantu besikhathi sangaleso sikhathi) zavela ngesikhathi samakhompiyutha we-vacuum tube. Kepha ngokwethulwa kwamayunithi wesigubhu ashibhile, ukusetshenziswa kwawo kwaphela.
Ukulandela amashumi eminyaka
Kamuva, ngawo-1970 nango-1980, ama-SS drives asetshenziswa kwimemori ye-semiconductor yama-supercomputer okuqala e-IBM, Amdahl, neCray, kepha ayesetshenziswa kakhulu ngenxa yenani eliphakeme kakhulu. Ngasekupheleni kweminyaka yama-1970, iGeneral Instruments yakhiqiza iROM (EAROM) eyayisebenza ngokufana nememori ye-NAND yakamuva. Ngeshwa, impilo yeminyaka eyishumi yayingafinyeleleki futhi izinkampani eziningi zashiya ubuchwepheshe.
Ngo-1976 iDataram yaqala ukuthengisa umkhiqizo obizwa ngeBulk Core, owawunikeza kuze kufike ku-2 MB wesitoreji sombuso esiqinile esihambisana namakhompyutha weDigital (DEC) kanye neDatha General (DG). Ngo-1978, iTexas Memory Systems yafaka idrayivu engu-16 kilobyte RAM solid state ezosetshenziswa izinkampani zikawoyela ukuthola imininingwane yokuzamazama komhlaba. Ngonyaka olandelayo, i-StorageTek yathuthukisa idrayivu yokuqala ye-RAM solid state.
Ubuhlakani besikhathi!
I-Sharp PC-5000, eyethulwa ngo-1983, isebenzise ama-cartridge wesitimela esiqinile ayi-128 KB aqukethe inkumbulo ye-bubble. Ngo-1984 iTallgrass Technologies Corporation yayine-40 megabyte tape backup drive nge-20 MB solid state drive. Idrayivu engu-20MB ingasetshenziswa esikhundleni se-hard drive. NgoSepthemba 1986, iSanta Clara Systems yethule iBatRam, uhlelo lokugcina ngobuningi lwe-4MB olunwebekayo lube yi-20MB kusetshenziswa amamojula wememori ye-4MB.
Ibhethri elishajekayo lakhiwe ephaketheni ukugcina okuqukethwe kwichip memory lapho i-matrix inganikwa amandla. Ngo-1987 kwangena ukungena kwe-EMC Corporation (EMC) emakethe ye-SSD, kwafakwa amadrayivu emakethe yamakhompyutha amancane. Kodwa-ke, ngo-1993 i-EMC yayisiphumile emakethe ye-SSD. Amadiski e-RAM asuselwa kusoftware ayesasetshenziswa ukusukela ngonyaka we-2009 ngoba ayi-oda lokuphakama ngokushesha kunamanye ubuchwepheshe, yize edla imithombo eminingi ye-CPU futhi abiza kakhulu nge-gigabyte ngayinye.
Ama-SSD amahle kakhulu asuselwa kuFlash
Ngo-1983, ikhompyutha ephathekayo yaba ngeyokuqala ukufaka izikhala ezine zesitoreji esikhiphekayo ngesimo se-flash-based solid-state drives, kusetshenziswa uhlobo olufanayo lwe-flash memory card. Amamojula weFlash abenomkhawulo wesidingo sokufomethwa ngokuphelele ukuthola isikhala kusuka kumafayela asusiwe noma aguquliwe; izinhlobo ezindala zamafayela asusiwe noma aguquliwe aqhubeka nokuthatha isikhala kuze kufomethwe imodyuli.
Ekuqaleni kuka-1995, kwamenyezelwa ukwethulwa kwama-state state based solid drives. Babenethuba lokungadingi amabhethri ukugcina idatha kwimemori (edingwa yizinhlelo zememori zangaphambili eziguquguqukayo), kepha bezingasheshi njengezixazululo ezisuselwa kwimemori yokufinyelela engahleliwe enamandla (i-DRAM). Kusukela lapho, ama-SSD asetshenziswe ngempumelelo njengokushintshwa kwe-hard disk drive (HDD) yizimboni zezempi nezasemkhathini, kanye nezinye izinhlelo zokusebenza ezibucayi zemishini.
Lezi zinhlelo zidinga isikhathi esinqunyiwe esiphakathi kwamanani okwehluleka (i-MTBF) ukuthi isimo esiqinile sishayela ngokufeza amandla abo okumelana nobubanzi obukhulu bokushaqeka, ukudlidliza kanye nokushisa. Cishe ngo-2007 i-SSD esekwe kwi-PCIe yethulwe ngokusebenza kokufaka / kokukhipha okungu-100.000 ngomzuzwana (IOPS) ekhadini elilodwa namandla okufika ku-320GB. I-1 terabyte (TB) flash SSD esebenzisa i- # 8 PCI Express interface ingafinyelela isivinini esikhulu sokubhala esingu-654MB / s kanye nesivinini sokufunda esiphezulu esingu-712MB / s.
Ama-Flash Flash Drives
Ama-Enterprise Flash Drives (EFDs) akhelwe ngokukhethekile izinhlelo zokusebenza ezidinga ukusebenza okuphezulu kwe-I / O (IOPS), ukuthembeka, ukusebenza kahle kwamandla, nokusebenza okungaguquguquki. Ezimweni eziningi, i-EFD iyi-SSD enesethi ephakeme yama-specs, uma kuqhathaniswa nama-SSD ajwayele ukusetshenziswa kuma-laptops. Azikho izindinganiso zamazinga ezilawula incazelo yama-EFDs, ngakho-ke noma yimuphi umkhiqizi we-SSD angafuna ukuthi akhiqize ama-EFDs lapho engakwazi ukuhlangabezana nezidingo empeleni.
Ukwakhiwa okuhle kakhulu kwe-SSD
Ama-Solid State Drives, noma ama-SSD, athathwa njengokuthuthuka kokugcina idatha lapho ethulwa emakethe, futhi ahlala eyidrayivu yokuzikhethela kuningi lomkhiqizo wokugcina we-Flash wabathengi nabezimboni. Ngoba amashayeli we-DED aqukethe izingxenye ezihambayo, ahlonyiswe kangcono kunama-hard drive, noma ama-HDD, ezimweni ezinzima, nawo agijima ngokushesha futhi ngaphandle komsindo ohambisana nama-hard drive. Enye yezinto ezibalulekile ekwakhiweni kwe-SSD yisilawuli.
Isilawuli
Isilawuli sinesibopho sokwakha ukuxhumana phakathi kwememori eku-SSD nakukhompyutha ephethe, futhi ngaphandle kwayo, i-SSD ibingaba yize. Ukuma kwesilawuli akubalulekanga kunendawo nendawo. Uma ubheka i-SSD, uzothola isilawuli sihleli ngemuva kwendawo lapho ikhadi lixhunywe khona empeleni ohlelweni lokusingathwa naphambi kwezakhi ze-NAND. Okuwukuphela kokuhlukile kulapho kugcinwa kwi-SSD encane.
Isilawuli sibhekele eminye yemisebenzi ebaluleke kakhulu ye-SSD. Lokhu kufaka phakathi ukulondolozwa kwesikhashana kokufunda nokubhala, i-ECC, ukulinganiswa kokugqoka, nokufunda ukuphathwa kokuphazamiseka. Iphinde yenze imephu emibi yokuvimba. Ngaphandle kwalezi zici, i-SSD ibizoguga ngaphambi kwesikhathi futhi kungenzeka ingasebenzi ngokuthembekile njengoba kudingeka.
I-SSD ngayinye ifaka i-plug-in efaka izinto ze-elekthronikhi ezixhuma izinto zememori ze-NAND kukhompyutha eyisingathile. Isilawuli yiprosesa eshumekiwe eyenza ikhodi yezinga le-firmware futhi ingesinye sezici ezibaluleke kakhulu ekusebenzeni kwe-SSD. Eminye yemisebenzi eyenziwa isilawuli ifaka:
- Gqoka ukulinganisa
- Ukwenza imephu engalungile
- Funda ukugeza futhi ufunde ukuphatha ukuphazamiseka
- Funda futhi ubhale ukulondolozwa kwesikhashana
- Ukuvuna
- Ukubethela
Ukusebenza
Ukusebenza kwe-SSD kungakala ngenombolo yama-chip chips we-NAND afanayo asetshenziswa kudivayisi. I-chip eyodwa ye-NAND ihamba kancane, ngenxa yesixhumi esibonakalayo esine-asynchronous I / O (8/16 bit) kanye nokubambezeleka okungeziwe kokusebenza okuyisisekelo kwe-I / O (okujwayelekile kwe-SLC NAND, ama-euro angama-25 ukubamba ikhasi le-4KB kusuka kumalungu afanayo kubhafa ye-I / O ekufundweni okukodwa, ama-250s ukwenza ikhasi le-4K kusuka kusipikha se-I / O ukuhlela ukubhala okukodwa, ama-2ms ukusula ibhulokhi engu-256KB).
Lapho amadivayisi amaningi we-NAND esebenza ngokufana ngaphakathi kwe-SSD, umkhawulokudonsa uyakalwa futhi ama-latency aphezulu angafihlwa, inqobo nje uma kukhona imisebenzi eyanele elindile nomthwalo usatshalaliswa ngokulinganayo phakathi kwamadivayisi. Amashayela we-SYSTEM ashesha kakhulu asebenzisa umugqa wedatha (ofana ne-RAID 0) nokungena ngaphakathi ekwakhiweni kwawo. Lokhu kunike amandla ukwakhiwa kwama-SSD ashesha kakhulu anezivinini ezisebenza kahle zokufunda / ukubhala ezingama-250MB / s ezinesixhumi esibonakalayo se-SATA 3 Gbit / s ngo-2009. Eminyakeni emibili kamuva, abalawuli bebanga labathengi be-SATA 6 Gbit / s SSD bangaxhasa isivinini. Funda / bhala ka-500 MB / s.
Memoria
Abakhiqizi abaningi be-SSD basebenzisa imemori ye-NAND ye-non-volatile ekwakhiweni kwama-SSD abo ngenxa yezindleko eziphansi uma kuqhathaniswa ne-DRAM kanye nokukwazi ukugcina idatha ngaphandle kokunikezwa kwamandla njalo, ukuqinisekisa ukuphikelela kwedatha kunqamuka kukagesi okungazelelwe. Ama-STATUS flash memory drive ahamba kancane kunezixazululo ze-DRAM, futhi amanye amadizayini okuqala abedlula kancane kunama-hard drive ngemuva kokusetshenziswa okuqhubekayo. Izixazululo ezisuselwa kwimemori ye-Flash zivame ukuhlanganiswa kufomu elijwayelekile lefomu ledrayivu yediski (1,8, 2,5, no-3,5-intshi), noma imidwebo emincane eyodwa, ehlanganisiwe ngenxa yememori ehlanganisiwe.
Amashayeli anentengo ephansi ngokuvamile asebenzisa imemori ye-multi-tier cell (MLC) flash, ehamba kancane futhi engethembeki kangako kunememori ye-flash single-tier cell (SLC). Lokhu kungancishiswa noma kubuyiselwe emuva ukwakheka kwangaphakathi kwe-SSD njengokungena ngaphakathi, izinguquko kuma-algorithms wokubhala, nokukhuphuka kokuhlinzekwa (amandla athe xaxa) afaka ama-algorithms wokulinganisa angasebenza nawo.
Imemori esekwe ku-DRAM
Ama-SSD asuselwa enkumbulweni eguquguqukayo afana ne-DRAM abonakala ngokufinyelela kwe-ultra-fast kwidatha (imvamisa engaphansi kwama-microsecond ayi-10) futhi isetshenziselwa ikakhulukazi ukusheshisa izinhlelo zokusebenza ebezizobanjwa ukubambezeleka kwama-flash SSD wendabuko noma ama-HDD. Uma amandla elahlekile, ibhethri linikeza amandla ngenkathi lonke ulwazi lukopishwa kusuka kwimemori yokufinyelela engahleliwe (RAM) kuya kusitoreji sokulondoloza. Lapho amandla ebuyiswa, imininingwane ikopishelwa emuva ku-RAM kusuka kusitoreji sokulondoloza futhi i-SSD iqala ukusebenza okujwayelekile (okufana nomsebenzi we-hibernate osetshenziswa ezinhlelweni zesimanje zokusebenza).
Ama-SSD alolu hlobo ajwayele ukufakwa amamojula we-DRAM wohlobo olufanayo asetshenziswa kuma-PC namaseva ajwayelekile, angashintshwa akhishwe ngamamojula amakhulu I-disk yokufinyelela kwimemori ekude nengaqondile (i-RIndMA disk) isebenzisa imishini yesibili ngenethiwekhi esheshayo noma uxhumano lwe-Infiniband (ngqo) ukuze lusebenze njenge-SSD esekwe ku-RAM, kepha ama-SSD amasha, asheshayo, asuselwa ku-flash, asevele etholakala ngo-2014 enza le nketho ingabi nzuzo kangako. Ngenkathi intengo ye-DRAM iqhubeka ukwehla, intengo yememori ye-flash yehla ngokushesha okukhulu. I-'flash ishibhile kune-DRAM 'crossover point yenzeke ngonyaka we-2004.
Ezinye izinhlobo zememori
Amanye ama-SSD asebenzisa i-MRAM. Amanye amadrayivu agodliwe asebenzisa i-DRAM ne-flash memory. Lapho ugesi ucishiwe, i-SSD ikopisha yonke idatha kusuka ku-DRAM yayo ukuze ikhanyise. Lapho amandla ebuya, i-SSD ikopisha yonke idatha kusuka ku-flash yakho iye ku-DRAM yakho. Amanye amadrayivu asebenzisa i-hybrid yamadiski ajikelezayo nememori ye-flash.
Ama-cache nama-buffers kuma-SSD amahle kakhulu
Ama-hard drive wendabuko afaka imemori ethile ngaphakathi kwehardware yedrayivu (ama-megabyte ambalwa, imvamisa ayisishiyagalombili, ayi-16, noma mhlawumbe athe xaxa) ukuze kwandiswe ukusebenza kokubona nokubhala okubonakalayo komsebenzisi. Uma idatha umsebenzisi afuna ukuyifunda noma ayibhale ingagcinwa ngaphakathi kwesilondolozi sokusebenza okuphezulu, iyunithi ingagcina idatha lapho okwesikhashana kumamojula wememori esheshayo.
Ngemuva kwalokhu, kuphethe ukwazisa isistimu yokusebenza ukuthi ukusebenza kuqediwe, ukuze ngemuva kwalokho iyunithi likwazi ukuphatha ukudluliswa kwedatha kusuka kunqolobane kuya kwimithombo yezokuxhumana ehamba kancane. Akusebenzi ngaso sonke isikhathi njengengxenye encane kakhulu yedatha ephelele kudrayivu ebingafakwa kunqolobane nganoma yisiphi isikhathi esisodwa, uma idatha ingafakwanga kunqolobane kufanele ifundwe kusuka kwabezindaba abahamba kancane.
Ama-SSD anomqondo ofanayo onenqolobane, ngaphandle kokuthi afaka amachipsi e-DRAM ngaphakathi kwehadiwe le-hardware ye-SSD kwi-SSD uqobo. Lokhu kungahle kusuka ku-64MB kuye kuma-gigabytes, futhi empeleni kusetshenziselwe ukufiphaza izicelo zokwenza ngcono impilo yedrayivu futhi kunikeze ukuqhuma okuncane kwezicelo zokufunda nokubhala ngokushesha okukhulu kunememori ejwayelekile yedrayivu engavumela. Lezi zinqolobane zibalulekile ezinhlelweni zokugcina zebhizinisi, kufaka phakathi amaseva wefayela asetshenziswe kakhulu kanye namaseva wedatha, kepha awabalulekanga kangako kubasebenzisi be-desktop kanye ne-laptop.
Ibhetri
Enye into kuma-SSD wokusebenza okuphezulu yi-capacitor noma uhlobo oluthile lwebhethri. Lokhu kubalulekile ukugcina ubuqotho bedatha ukuze idatha yesilondolozi ingafakwa kudrayivu lapho kucisha ugesi; abanye baze bakwazi ukuphatha amandla isikhathi eside ngokwanele ukugcina idatha kunqolobane kuze kubuyiselwe amandla. Endabeni yememori ye-MLC flash, inkinga ebizwa ngenkohlakalo yekhasi eliphansi
Le nkinga ingenzeka lapho imemori ye-MLC flash ilahlekelwa amandla ngenkathi ihlela ikhasi eliphezulu. Umphumela uba ukuthi idatha ephephile yokuqagela futhi ecatshangelwe ingenza umonakalo omkhulu uma imemori ingahambisani ne-supercapacitor uma kwenzeka ukulahleka kwamandla kungazelelwe. Le nkinga ayikho nge-SLC flash memory.
Isixhumi esibonakalayo
I-interface yokusingathwa ayiyona ingxenye ye-SSD, kepha iyingxenye ebalulekile yedrayivu. Imvamisa yakhelwe kwisilawuli okuxoxwe ngaso ngenhla, imvamisa kungenye yezindawo zokuxhumana ezitholakala kuma-hard drive. Lokho okushiwo kufaka:
- I-serial Attached SCSI (SAS,> 3,0 Gbit / s) - imvamisa itholakala kumaseva
- I-serial ATA (SATA,> 1,5 Gbit / s)
- I-PCI Express (PCIe,> 2.0 Gbit / s)
- I-Fiber Channel (> 200 Mbit / s) - cishe kuphela kumaseva

Noma kunjalo, izindleko ze-flash drive zehliswe ngokwanele ukuthi ukusebenza kwayo okuphezulu kube nenzuzo. Ukusebenza kungukhiye ngempela: Uma ama-hard drive anciphisa imininingwane yolwazi yokuthengiselana nezinye izinhlelo zokusebenza ezinamandla, khona-ke ukuthenga ama-hard drive wokukwazi ukuthenga kungumnotho wamanga.
Amandla okugcina idatha amancane
Amandla we-SSD NAND anciphisa ama-hard drive ngenxa yemikhawulo yokubhala yeseli lememori le-NAND. Amaseli wememori amaningi esifundeni, ubukhulu obuphezulu i-SSD izokufeza. Kodwa-ke, i-flat NAND (2D) ingabamba kuphela inani elilinganiselwe lamaseli wememori ngaphambi kokuba amaseli aqale ukwehluleka. Ekuphenduleni, abacwaningi bakhulisa i-3D NAND ngokufaka amaseli wememori ngokuqondile nangokuqondile.
Lokhu kunika amandla i-3D NAND ukufeza ukuminyana okuphezulu, ukusetshenziswa kwamandla okuphansi, ukukhuthazela okungcono nokufundwa, ngezindleko eziphansi ngegigabyte ngayinye. Ama-state state solid abiza kakhulu futhi athengiswa ngentengo enkulu ngokungafani nama-hard drive ajwayelekile. Ngakho-ke, ama-SSD atholakala kakhulu ngamanani amancane, angabizi kakhulu wesitoreji. Umthamo wesitoreji uqobo ungaphansi kuka-160GB.
Umjikelezo wokuphila omfushane
Ama-SSD anomjikelezo wokubhala onomkhawulo kakhulu kunama-hard drive ngaphambi kokwehluleka. Isizathu esikhulu ukuthi ama-SSD awakwazi ukubhala ngaphezulu kwamabhulokhi akhona, kepha kufanele asule amabhulokhi kuqala bese ebhala idatha entsha. Le nqubo ekugcineni ithinta ubuqotho beseli lememori. I-NAND ibhala yehlukile ngokuya ngenani lamabhithi ngeseli ngalinye; i-single-level cell NAND flash isekela imijikelezo yokubhala engama-50.000 kuya ku-100.000, iseli lamazinga amaningi ngokuvamile lithatha kuze kube yimijikelezo yokubhala engama-3.000, i-eMLC (ibhizinisi MLC) igcina imijikelezo yokubhala engafika ku-10.000, amaseli ezinqanaba ezintathu aphansi ngemijikelezo yokubhala engu-300-1000 futhi I-3D NAND ingafinyelela imijikelezo yokubhala eyi-1500-3000.
Awahambelani namafayela
Amabhizinisi afuna ukwazi ukufinyelela, ukuhlaziya, nokwenza imali ngamafayela abo edatha. Ngenombolo yabo elinganiselwe yemijikelezo yokubhala, ama-SSD awakulungele ukufaka kungobo yomlando okusebenzayo nokuhlaziywa okuphindaphindiwe kumasethi wedatha afanayo. Njengoba umbono wamafayela asebenzayo kuyikhono lokufinyelela kudatha ngokuthanda, lokhu kweqa inani lemijikelezo yokubhala amangqamuzana ememori angamelana nayo.
Ukulahleka kwedatha elahlekile
Ukwehluleka ukubuyisa idatha yakudala kungenye yezinkinga ezinkulu ze-SSD. Idatha isuswe unomphela futhi isuswe ngokuphelele kumadrayivu. Kodwa-ke, lokhu kuyinzuzo maqondana nokuphepha kwedatha, ukususwa kwedatha unomphela kungaholela emiphumeleni engalungiseki emicimbini ethile lapho kungekho khona isipele sedatha esusiwe.
Ijubane lokubhala elihamba kancane
Amanye ama-SSD angabizi kakhulu, ikakhulukazi izinhlobo ezisuselwa ku-MLC, eza nesivinini sokubhala esihamba kancane uma kuqhathaniswa nesivinini sokufunda. Lezi zivinini zihamba kancane kunesivinini sokubhala kuma-hard drive ajwayelekile.
Ubuchwepheshe bamuva
Ezikhathini zamuva nje, ukusetshenziswa kwe-SSD kuye kwanda okuholela ezinkingeni ezahlukahlukene. Lezi zinkinga kufanele zixazululwe ngaphambi kokuthola ukusebenza okuhle kuma-SSD. Isibonelo, amasistimu okusebenza weWindows asetshenziswe ngaphambi kweWindows 7 awazange enzelwe ama-SSD. Ngakho-ke, ukusebenzisa i-solid state drive ngesistimu yokusebenza engenziwanga lutho, efana neWindows Vista, kuvame ukunciphisa ukusebenza kwedrayivu futhi kunciphise isikhathi sayo sokuphila.
Amandla aphezulu
Ama-power-state drives asebenzisa ubuchwepheshe be-DRAM adinga amandla amaningi kunama-hard drive ajwayelekile. Lawa madrayivu aqhubeka nokudla amandla lapho uhlelo luqala kanti i-hard drive ejwayelekile ngeke.
Umthelela emandleni nasekuthembekeni
Okumaphakathi ekwakhiweni kwe-flash ye-NAND kungenzeka ukulimala okungenakulungiswa esangweni elintantayo ngenxa yokusula okuningi nemijikelezo yohlelo. Kalula nje, ukukhuthazela (okusho ukuthi inani lemijikelezo ibhulokhi lingasulwa futhi lihlelwe ngaphakathi) lilinganiselwe. Izinkambu zikagesi eziqine ngokwanele ezisetshenziswa phakathi nohlelo nokusula umjikelezo; ziyakwazi ukulimaza isango elintantayo, okuthi uma lonakele, liguqule izici zeseli le-NAND.
Amandla ale nkinga ahlanganiswa lapho i-SSD inenombolo elinganiselwe yamabhulokhi we-NAND noma inani elinqunyiwe lomthamo ongasetshenziswa. Ngakho-ke, imijikelezo yohlelo / yokusula eminingi isuselwa kunani ledatha elibhalelwe idivayisi (noma umthwalo womsebenzi), ukusebenza kahle kwemijikelezo yohlelo okusatshalaliswa kuwo wonke amaseli wedivayisi ye-flash ngokulinganayo (noma ukulinganisa ukugqoka), noma ukusebenza kahle phakathi kwedatha okubhalwe kwimidiya ye-NAND nemininingwane etholwe kumgcini (noma ukuphindaphindwa kokubhala) kungadala ukuthi amaseli e-NAND agqoke ngaphambi kwesikhathi nangokweqile ukukhuthazeka kwedivayisi jikelele kwe-SSD nokufinyeleleka kwedatha ekuyo.
Dinga imijikelezo eyengeziwe
Ngoba imijikelezo yohlelo eyengeziwe iyadingeka ukusebenzisa i-MLC NAND nefasitela layo elincane lamandla kagesi, iseli le-MLC NAND lizoguga ngokushesha kuneseli le-SLC NAND ngoba isignali yomsindo we-NAND medium yehlisa isikhathi. Kubalulekile ukubona umehluko phakathi kwalezi zimfanelo ze-SLC ne-MLC flash ngoba kuthinta ukumelana okucaciswe ngebhulokhi enikeziwe:
- I-SLC NAND ivame ukucaciswa kumijikelezo yokubhala / yokusula eyi-100.000 ngebhulokhi ngayinye.
- I-MLC NAND ichazwa imijikelezo yokubhala / yokusula eyi-10.000 ngebhulokhi ngayinye.
Ngokwengeziwe, ukugcinwa kwedatha (noma ubuqotho bemininingwane egcinwe kuseli le-flash ngokuhamba kwesikhathi) kuthinteka yisimo sesango elintantayo esitokisini se-NAND lapho amazinga kagesi abucayi khona. Ukuvuza kuya noma kusuka esangweni ezintantayo, okuvame ukushintsha kancane izinga lamandla eseli kusuka ezingeni lalo lokuqala liye ezingeni elihlukile ngemuva kokuhlela noma ukusula iseli, kungashintsha izinga lamandla kagesi.
Leli zinga eliguquliwe lingahunyushwa ngokungalungile njengenani elihlukile lokuqonda ngohlelo. Ngakho-ke, ngenxa yokubekezelelana kwamandla kagesi aqinile phakathi kwamazinga e-MLC kunamazinga we-SLC, amaseli we-MLC flash kungenzeka ukuthi athintwe yimiphumela yokuvuza. Ngakho-ke, kufanele kunakekelwe ukuqinisekisa amandla wokugcina idatha wesikhathi eside we-SLC ne-MLC NAND lapho isetshenziswa ekugcineni ibhizinisi. Ukuphendula lezi zinkinga, ama-NAND flash OEMs asanda kumemezela ubuchwepheshe (obubizwa nge-Enterprise MLC, noma i-eMLC) obandisa kakhulu impilo yesitoreji esisekela i-flash yezinhlelo zebhizinisi.
Amasu asetshenziselwa ukuthembeka okususelwa ku-NAND
Phezulu, izinkinga eziningi ezihlotshaniswa ne-NAND njengendawo yokugcina zingabonakala zinzima kakhulu noma ziyinselelo yokuthi ubuchwepheshe bungasetshenziswa endaweni yebhizinisi. Kodwa-ke, amabhizinisi wombuso athandwayo ahlanganisa inqwaba yamasu athuthukile nobuhlakani ukusiza ukunqoba imikhawulo yobulukhuni nokwethembeka ezingeni le-NAND flash media.
Ikhodi yokulungisa iphutha (ECC)
I-ECC isetshenziselwa ukuthola nokulungisa amaphutha ngokungeza izingcezu ezingeziwe kudatha. Ama-algorithm we-ECC, afana namakhodi weReed-Solomon, i-Hamming coding, nokunye, asetshenziswa kakhulu ezinhlelweni zokugcina. Ngokuvamile, lapho kusetshenziswa ama-bits e-ECC amaningi, izinga lokulungiswa kwamaphutha liyanda. Ngakho-ke, i-SSD ene-ECC esebenza kahle izokwazi ukulungisa amaphutha amaningi, okugcina kuthuthukisa isikhathi sokugqoka.
Gqoka amasu wokulinganisa
Ukulinganiswa kwe-Wear kuyinqubo esetshenziswa yi-SSD ukunciphisa umthelela wokukhawulelwa kokumelana ne-NAND ngokusabalalisa imijikelezo yohlelo kuwo wonke amaseli kudivayisi ye-flash ngokulinganayo. Amasu amabili ayisisekelo, amile futhi anamandla, asetshenziswa kakhulu kuma-SSD ukuphatha ukufinyelela kwimidiya ye-NAND. Lokhu kuvimbela idatha engafinyelelwa njalo ukuthi igcinwe kubhulokhi enikeziwe isikhathi eside.
Ukulinganiswa kokugqoka okuqinile kuklanyelwe ukusabalalisa idatha ngokulinganayo kulo lonke uhlelo ngokuthola amabhlokhi asetshenzisiwe angatheni bese kubhalwa idatha kulezo zindawo. Ukulinganiswa kokugqoka okunamandla kusabalalisa idatha kumabhulokhi amahhala noma angasetshenziswanga. Ekugcineni, ukuhlanganiswa kwalezi zindlela zokulinganisela ukugqoka kwandisa impilo ye-SSD ngokusabalalisa idatha kuwo wonke amaseli wedivayisi ngokulinganayo ukugwema ukugqokwa kwamaseli ngamanye.
Ukusetshenziswa kwamabhulokhi wokugcina (noma ukulayisha ngokweqile)
Ukuhlinzeka ngamabhulokhi wokugcina wamandla we-NAND angeziwe kungenye indlela yokuthuthukisa ukukhuthazela. Isibonelo, i-SSD emakethwa njenge-25 GB SSD ingakhombisa amandla angama-25 GB womthamo womsebenzisi wokugcina idatha. Noma kunjalo, i-SSD ingakhiwa nge-32GB yamandla weqiniso we-NAND. I-7GB ephezulu (noma amabhlogo wokugcina) kulesi sibonelo ingasetshenziselwa ukuthuthukisa ukusebenza kahle kokulinganiswa kokugqoka nokunye ukusebenza kohlelo / okucacile ukwandisa ukukhuthazela nokusebenza ezingeni ledivayisi. Lokhu kwaziwa ngokujwayelekile njengokukhishwa ngokweqile.
Bhafa idatha
Ku-SSD, futhi nange-hard drive, idatha ebhafa nenani elincane lememori ye-DRAM ingathuthukisa ukusebenza. Ku-SSD, bhafa idatha; ibuye ithuthukise ukuqina kwezinga ledivayisi ngokwandisa ukubhala, ukukhawulela uhlelo / ukusula imijikelezo, nokususa noma yikuphi ukungafani phakathi kosayizi webhulokhi nosayizi wedatha.
Ama-SSD amahle kakhulu emakethe namuhla
Ukushintshela kudrayivu yesimo esiqinile kungukuthuthuka okuhle kakhulu ongakwenzela i-PC yakho.
