Lapho ukhetha i-stateD drive eqinile ye-SSD yokusetshenziswa kwasekhaya, ungahle uhlangane nesici esifana nohlobo lwenkumbulo esetshenzisiwe futhi uzibuza ukuthi yikuphi okungcono - i-MLC noma i-TLC (ungathola nezinye izindlela zokukhetha uhlobo lwenkumbulo, isibonelo, i-V-NAND noma i-3D NAND ) Futhi muva nje kwavela amanani entengo akhangayo ngememori ye-QLC
Kulesi sibuyekezo sabaqalayo, sinemininingwane mayelana nezinhlobo zememori ye-flash esetshenziswe kuma-SSD, izinzuzo nezinzuzo zazo, nokuthi iyiphi inketho engathandeka kakhulu lapho uthenga i-state state drive. Kungase futhi kube usizo: Ilungiselela i-SSD yeWindows 10, Ungayidlulisa kanjani iWindows 10 kusuka ku-HDD iya ku-SSD, Ungathola kanjani ijubane le-SSD.
Izinhlobo zememori ye-flash esetshenziswe ku-SSD ukusetshenziswa ekhaya
I-SSD isebenzisa inkumbulo ye-flash, okuyi-cell cell ehlelwe ngokuqondile ngokususelwa kuma-semiconductors, angahluka ngohlobo.
Ngokujwayelekile, inkumbulo ye-flash esetshenziswe kuma-SSD ingahlukaniswa ngezinhlobo ezilandelayo.
- Ngomgomo wokubhala okufundwayo, cishe wonke ama-SSD atholakalayo abathengisi angawodidi lwe-NAND.
- Ngokobuchwepheshe bokugcina imininingwane, imemori ihlukaniswe nge-SLC (i-Cell-level Cell) ne-MLC (i-Multi-level Cell). Esimweni sokuqala, iseli lingagcina ulwazi olulodwa, okwesibili - okungaphezu kokukodwa. Ngasikhathi sinye, kwi-SSD yokusetshenziswa kwasekhaya ngeke uthole inkumbulo ye-SLC, yi-MLC kuphela.
Ngakolunye uhlangothi, i-TLC nayo ingeyohlobo lwe-MLC, umehluko ukuthi esikhundleni semithi e-2 yolwazi ingagcina izingcezu ezi-3 zolwazi endaweni yememori (esikhundleni se-TLC ungabona ukubizwa kwe-3-bit MLC noma i-MLC-3). Okusho ukuthi, i-TLC iyi-subspecies yememori ye-MLC.
Yikuphi okungcono - i-MLC noma i-TLC
Ngokuvamile, inkumbulo ye-MLC inezinzuzo ngaphezulu kwe-TLC, okuyinhloko okuyikhona:
- Ijubane eliphakeme.
- Impilo yenkonzo ende.
- Ukusetshenziswa kwamandla okuncane.
Okubi yintengo ephakeme ye-MLC ngokuqhathaniswa ne-TLC.
Noma kunjalo, kufanele kukhunjulwe ukuthi sikhuluma "ngecala elijwayelekile", kumadivayisi wangempela athengiswayo ongabona:
- Ijubane lokusebenza okulinganayo (ezinye izinto ziyalingana) kuma-SSD anenkumbulo ye-TLC neMLC exhunywe ngesibonisi se-SATA-3. Ngaphezu kwalokho, abashayeli abathile abasuselwa ku-TLC nge-PCI-E NVMe kwesinye isikhathi bangashesha ukudlula ngemishini efana neyentengo efanayo nge-PCI-E MLC (noma kunjalo, uma sikhuluma "ngokuphela kokugcina", ama-SSD abiza kakhulu futhi asheshayo, asaqhubeka Imemori ye-MLC isetshenziswa kaningi, kepha futhi hhayi njalo).
- Izikhathi Ezinde Zokuqinisekisa (i-TBW) yememori ye-TLC evela kumenzi oyedwa (noma umugqa owodwa wokushayela) kuqhathaniswa nememori ye-MLC evela komunye umenzi (noma omunye umugqa we-SSD).
- Ifana nokusetshenziswa kwamandla - ngokwesibonelo, idrayivu ye-SATA-3 enenkumbulo ye-TLC ingadla amandla angaphansi kweshumi kune-PCI-E drive enememori ye-MLC. Ngaphezu kwalokho, ngohlobo olulodwa lwenkumbulo ne-interface eyodwa yokuxhuma, umehluko ekusebenziseni amandla futhi kuhluke kakhulu ngokuya nge-drive ethile.
Futhi lokhu akuyona yonke imikhawulo: ijubane, impilo yensiza nokusetshenziswa kwamandla kuzokwehluka futhi kusukela "esizukulwaneni" sedrayivu (okusha, njengomthetho, kuthuthukile kakhulu: njengamanje ama-SSD ayaqhubeka nokukhulisa nokwenza ngcono), umthamo wawo ophelele nenani lesikhala samahhala uma usebenzisa futhi ngisho nezimo zokushisa lapho usebenzisa (kwizishayeli ze-NVMe ezisheshayo).
Ngenxa yalokhu, isinqumo esiqinile nesinembile sokuthi i-MLC ingcono kune-TLC ngeke idluliselwe - ngokwesibonelo, ngokuthenga i-SSD enamandla kakhulu futhi entsha ene-TLC kanye nesethi engcono yezimpawu, unganqoba ngazo zonke izindlela uma uqhathanisa nokuthenga idrayivu ne-MLC ngentengo efanayo, t .e. wonke amapharamitha kufanele acatshangelwe, futhi ukuhlaziywa kufanele kuqalwe ngesabelomali sokuthenga esingabizi (ngokwesibonelo, ukukhuluma ngesabelomali esingama-ruble angama-10,000, imishini evame ukuhanjwa ngememori ye-TLC izothanda i-MLC kuwo womabili amadivayisi we-SATA ne-PCI-E).
Ama-SSD anememori ye-QLC
Kusukela ukuphela konyaka owedlule, abashayeli bezindawo eziqinile abanememori ye-QLC (i-quad-level cell, i.e. izingcezwana ezi-4 kuseli elilodwa lememori) bavele bathengiswa, futhi, mhlawumbe, ngo-2019 kuzoba nokushayela okuningi okunjalo, futhi izindleko zabo zithembisa ukuheha.
Imikhiqizo yokugcina ibonakala ngezimpawu ezilandelayo ezinhle nokuqhathaniswa ne-MLC / TLC:
- Izindleko eziphansi nge-gigabyte ngayinye
- Inkumbulo enkulu kakhulu yokugqoka futhi, ngokweqiniso, amathuba amakhulu wokuqoshwa kwamaphutha wedatha
- Ijubane lokubhala idatha
Ukukhuluma ngezinombolo ezithile kusenzima, kepha ezinye izibonelo zalokhu esele zithengiwe zingafundwa: ngokwesibonelo, uma uthatha cishe i-512 GB M.2 SSD drive Drives from Intel based in QLC 3D NAND and TLC 3D NAND memory, funda imininingwane yomkhiqizi bona:
- Ama-ruble ayizinkulungwane eziyi-6,7 maqondana nama-ruble ayi-10-11. Futhi ngezindleko ze-512 GB TLC, ungathenga i-1024 GB QLC.
- Umthamo omisiwe wemininingwane eqoshiwe (i-TBW) yi-100 TB ngokumelene ne-288 TB.
- Ijubane lokubhala / lokufunda ngu-1000/1500 kuqhathaniswa ne-1625/3230 Mb / s.
Ngakolunye uhlangothi, ama-cons angakwazi ukwedlula izinzuzo zezindleko. Ngakolunye uhlangothi, ungabheka lezo zikhathi ezinjalo: kumadiski we-SATA (uma une-interface enjalo kuphela) ngeke uqaphele umehluko ngejubane futhi ukwanda kwejubane kuzobaluleka kakhulu uma kuqhathaniswa ne-HDD, futhi ipharamitha ye-TBW ye-QLC SSD ingu-1024 GB (okuyi Isibonelo sibiza okufanayo nge-512 GB TLC SSD) esivele sine-200 TB (abashayeli bezindawo eziqinile "baphila" isikhathi eside, ngenxa yendlela aqoshwe ngayo).
Inkumbulo ye-V-NAND, i-3D NAND, i-3D TLC, njll.
Ezichazelweni zokushayela kwe-SSD (ikakhulukazi uma kukhulunywa nge-Samsung ne-Intel) ezitolo nasekubuyekezweni ungathola ukubizwa kwe-V-NAND, 3D-NAND futhi kufane nezinhlobo zememori.
Lokhu kudalulwa kukhombisa ukuthi amaseli wememori ye-flash atholakala kuma-chips ezingqekweni eziningana (kuma-chip elula amaseli atholakala ungqimba olulodwa, ngaphezulu ku-Wikipedia), kuyilapho le inkumbulo efanayo ye-TLC noma ye-MLC, kepha lokhu akuboniswa ngokusobala yonke indawo: Isibonelo, kuma-Samsung SSDs uzobona kuphela ukuthi inkumbulo ye-V-NAND isetshenziswa, noma kunjalo, imininingwane yokuthi umugqa we-EVO usebenzisa i-V-NAND TLC, futhi umugqa we-PRO awukhombisi njalo i-V-NAND MLC. Futhi manje sekuqhamuke ama-QLC 3D NAND Drives.
Ingabe i-3D NAND ingcono kunememori eplanethi? Kushibhile ukwenza futhi izivivinyo ziphakamisa ukuthi namuhla kwimemori ye-TLC, inketho enezici eziningi ngokuvamile isebenza kahle futhi ithembekile (ngaphezu kwalokho, i-Samsung ithi inkumbulo ye-V-NAND TLC isebenza kangcono futhi impilo yenkonzo kune-MLC eplanethi). Noma kunjalo, kwimemori ye-MLC, kufaka phakathi uhlaka lwamadivayisi womenzi ofanayo, lokhu kungenzeka kungabi njalo. Mina. futhi, konke kuncike kudivayisi ethile, isabelomali sakho namanye amapharamitha okufanele afundwe ngaphambi kokuthenga i-SSD.
Ngingajabulela ukuncoma i-Samsung 970 Pro okungenani i-1 TB njengenketho enhle yekhompyutha yasekhaya noma i-laptop, kepha imvamisa kuyathengwa amadiski ashibhile, lapho kufanele utadishe ngokucophelela lonke isethi yezimpawu bese uziqhathanisa nalokho okudingekayo kusukela ku-drive.
Ngakho-ke ukuntuleka kwempendulo ecacile, nokuthi hlobo luni lwememori olungcono. Vele, i-SSD enamandla enama-MLC 3D NAND ngokwemigomo yeqoqo lezimpawu izophumelela, kepha inqobo kuphela uma lezi zici zibhekwa zodwa eceleni kwentengo ye-drive. Uma sithathela le pharamende, angikukhiphi ngaphandle kokuthi kungenzeka ukuthi amadiski e-QLC alungele abanye abasebenzisi, kepha "indawo ephakathi" inkumbulo ye-TLC. Futhi akunandaba ukuthi ukhetha yiphi i-SSD, ngincoma ukuthatha ama-backups wedatha ebalulekile.
