Uma ukhetha SSD SSD ukusetshenziswa ekhaya, ungase uhlangabezane nesici ezifana uhlobo inkumbulo esetshenzisiwe futhi uzibuze ukuthi MLC noma TLC kungcono (ungase futhi uhlangabezane nezinye izinhlobo izinkumbulo zememori, isibonelo, V-NAND noma 3D NAND ). Kanti futhi, maduze nje kunezinkampani ezihamba phambili ezihamba phambili ezinomthamo we-QLC.
Lokhu kubuyekezwa kwabaqalayo kubonisa izinhlobo zememori ye-flash esetshenziselwa ama-SSD, izinzuzo nezinkinga zabo, futhi yiziphi zezinketho ezingase zikhetheke uma uthenga i-drive-state drive. Kungasiza futhi: Ukusetha i-SSD ye-Windows 10, Ukudlulisa i-Windows 10 kusuka kwi-HDD kuya kwi-SSD, Indlela yokukwazi ijubane le-SSD.
Izinhlobo zememori ye-flash esetshenziselwa i-SSD yokusetshenziswa ekhaya
I-SSD isebenzisa inkumbulo ye-flash, okuyinto amangqamuzana enkumbulo ahlelwe ngokukhethekile asekelwe kuma-semiconductors, angase ahluke ngohlobo.
Ngokuvamile, imemori ye-flash esetshenziselwa i-SSD ingahlukaniswa kulezi zinhlobo ezilandelayo.
- Ngomgomo wokufunda-ukubhala, cishe wonke ama-SSD abathengi athengiswa emakethe angomhlobo we-NAND.
- Ngokusho kobuchwepheshe bokugcina ulwazi, inkumbulo ihlukaniswe yi-SLC (i-Single-level Cell) ne-MLC (Multi-level Cell). Esimweni sokuqala, iseli lingagcina ulwazi oluthile, okwesibili, okungaphezulu kweyodwa. Kulesi simo, kwi-SSD yokusetshenziswa ekhaya, ngeke uthole imemori ye-SLC, i-MLC kuphela.
Ngokufanayo, i-TLC iphinde ibe yohlu lwe-MLC, umehluko wukuthi esikhundleni sezinguquko ezimbili zolwazi lungagcina ama-bits 3 elwazi kumemori ye memori (esikhundleni se-TLC ungabona i-3-bit MLC noma i-MLC-3). Okusho ukuthi i-TLC iyinhlangano ye-MLC memory.
Yikuphi okungcono - i-MLC noma i-TLC
Ngokuvamile, inkumbulo ye-MLC inezinzuzo ngaphezu kwe-TLC, okuyinhloko yayo:
- Isivinini esiphezulu somsebenzi.
- Ukuphila komsebenzi omude.
- Ukusebenzisa amandla okuphansi.
Ukungalungi kuyinani eliphakeme le-MLC eliqhathaniswa ne-TLC.
Nokho, kufanele kukhunjulwe ukuthi sikhuluma "ngecala elijwayelekile", kumadivayisi wangempela athengiswa ngokudayiswa ungabona:
- Isivinini sokusebenza esifanayo (enye imingcele ilingana) ye-SSD ene-TLC kanye ne-MLC memory, exhunywe nge-SATA-3 interface. Ngaphezu kwalokho, ukushayela komuntu ngamunye okusekelwe kwimemori ye-TLC nge-interface ye-PCI-E NVMe ngezinye izikhathi kungashesha kunamashayela we-PCI-E MLC enamanani afanayo (noma kunjalo, uma sikhuluma "nge-top-end", ama-SSD abiza kakhulu futhi asheshayo, namanje Imemori yeMLC ivame ukusetshenziswa, kodwa hhayi ngaso sonke isikhathi).
- Isikhathi eside sewaranti (TBW) somemori we-TLC yomkhiqizi oyedwa (noma enye umugqa wokushayela) uma kuqhathaniswa nememori ye-MLC yomunye umkhiqizi (noma elinye umugqa we-SSDs).
- Ngokufanayo nokusetshenziswa kwamandla - isibonelo, i-SATA-3 drive ne-TLC inkumbulo ingadla amandla angaphansi kwesishumi kunomshayeli we-PCI-E ne-MLC memory. Ngaphezu kwalokho, ngenhlobo eyodwa yememori kanye ne-interface eyodwa yokuxhumana, umehluko ekusetshenzisweni kwamandla ubuye uhluke kakhulu kuye ngokushayela okuqondile.
Futhi akuyona yonke imingcele: ijubane, ukuphila komsebenzi kanye nokusetshenziswa kwamandla kuzophinde kuhluke "kwesizukulwane" sedrayivu (labo abasha ngokuvamile baphelele kakhulu: okwamanje i-SSD iyaqhubeka nokuguquka nokuthuthukisa), ivolumu yayo yonke nenani lesikhala samahhala uma usebenzisa futhi ngisho nemodi yokushisa uma isetshenziselwa (for fast drives NVMe).
Ngenxa yalokho, isinqumo esiqinile futhi esinembile ukuthi i-MLC ingcono kune-TLC ayikwazi ukukhishwa - ngokwesibonelo, ngokuthola i-SSD enekhono futhi entsha ne-TLC nezimpawu ezingcono, ungakwazi ukunqoba kuzo zonke izici uma uqhathaniswa nokuthenga idrayivu nge-MLC ngentengo efanayo, t . Zonke izilinganiso kufanele zicatshangelwe, futhi ziqale ukuhlaziywa ngesabelomali esitholakalayo sokuthenga (isibonelo, uma ukhuluma ngesabelomali se-ruble angama-10 000, evame ukushayela imemori ye-TLC izokhethwa ku-MLC kokubili amadivayisi we-SATA nama-PCI-E).
Imemori ye-SSLC ne-QLC inkumbulo
Kusukela ekupheleni konyaka odlule, ukuqhutshwa kombuso oqinile ne-QLC inkumbulo (i-quad-level cell, okungukuthi ama-4 bits kumemori eyodwa yememori) ivele emakethe, futhi, mhlawumbe, ngo-2019 ama-disks anjalo azoba ngaphezulu, futhi inani lawo lithembisa ukukhangisa.
Imikhiqizo yokugcina ibonakala yizinzuzo ezilandelayo kanye neqhwa eliqhathaniswa neMLC / TLC:
- Izindleko ezincane gigabyte ngayinye
- Ukukhunjulwa okukhulu kwememori ukugqoka futhi, ngokuyisisekelo, amathuba okuba amaphutha lapho ubhala idatha
- Isivinini sokubhala idatha esincane
Kusadingeka ukukhuluma ngezinombolo ezithile, kodwa ezinye izibonelo ezivela kulabo asebevele zikhona emakethe zingahlolwa: isibonelo, uma uthatha cishe imoto eyi-M.2 SSD efanayo ne-512 GB evela ku-Intel esekelwe kumemori ye-QLC 3D NAND ne-TLC 3D NAND, funda imininingwane echazwe ngumenzi , sizobona:
- 6-7 ama-ruble ayizinkulungwane ezingu-10-11. Futhi ngentengo ye-512 GB TLC ungathenga i-1024 GB QLC.
- Umthamo omisiwe wemininingwane eqoshiwe (TBW) yi-TB eyi-100 ngokumelene ne-288 TB.
- Isivinini sokubhala / sokufunda singu-1000/1500 ngokumelene no-1625/3230 MB / s.
Ngakolunye uhlangothi, ukungalungi kungase kuvelele izinzuzo zezindleko. Ngakolunye uhlangothi, ungakwazi ukucabanga ngalezi zinsuku: ngoba izinkampani ze-SATA (uma unesibonakaliso esinjalo kuphela) ngeke uqaphele umehluko ngesivinini futhi ukuzuza kwejubane kuzoba okuphawuleka kakhulu uma kuqhathaniswa ne-HDD, kanti ipharamitha ye-TBW ye-QLC SSD ingu-1024 GB Isibonelo sibiza okufana ne-TLC SSD ye-512 GB), kakade i-TB engu-200 (ama-broad-state drives asebenzayo "aphile" isikhathi eside, esixhunywe ngendlela ababhaliwe kuyo).
Imemori V-NAND, 3D NAND, 3D TLC, njll.
Ezinchazeni ze-SSD drives (ikakhulukazi uma sikhuluma nge-Samsung ne-Intel) ezitolo kanye nokubuyekezwa ungathola ukukwaziswa kwe-V-NAND, i-3D-NAND nokufana nezinhlobo zememori.
Le ncazelo ibonisa ukuthi amangqamuzana e-flash memory agcinwe kuma-chips emigqeni eminingi (e-chips elula, amangqamuzana afakwe emgqeni owodwa, ngokuningiliziwe - ku-Wikipedia), kuyilapho lokhu kuyimemori efanayo ye-TLC noma ye-MLC, kodwa hhayi yonke indawo kuboniswa ngokucacile: isibonelo, nge-Samsung SSDs, uzobona kuphela ukuthi imemori ye-V-NAND isetshenzisiwe, kodwa ulwazi ukuthi i-V-NAND TLC lisetshenziselwa umugqa we-EVO ne-V-NAND MLC ayibonwanga njalo emgqeni we-PRO. Futhi manje kubonakala sengathi kuqhutshwa i-QLC 3D NAND.
Ingabe i-3D NAND ingcono kunememori "yokuhlela"? Kuyinto engabizi ukukhiqiza nokuhlola ukuthi namuhla inkumbulo ye-TLC iningi le-multi-layered version ngokuvamile liyasebenza futhi linokwethenjelwa (ngaphezu kwalokho, i-Samsung ithi imemori ye-V-NAND TLC inezici zokusebenza ezingcono kumadivayisi wabo) ukuqina kune-MLC planar). Kodwa-ke, ukuze inkumbulo ye-MLC, kufaka phakathi kwamadivayisi womkhiqizi oyedwa, lokhu kungenzeka ukuthi akunjalo. Yebo futhi, konke kuxhomeke kudivayisi ethize, isabelomali sakho neminye imingcele okufanele ifundwe ngaphambi kokuthenga i-SSD.
Ngingakujabulela ukutusa i-Samsung 970 Pro okungenani i-TB engu-1 njengendlela enhle yekhompiyutha yekhaya noma i-laptop, kepha ngokuvamile kuyathengwa ama-disks ashibhile, okudingeka ufunde ngokucophelela yonke iqoqo lezici bese uwaqhathanisa nalokho okudingekayo kwidrayivu.
Ngakho ukungabi nempendulo ecacile, futhi yiyiphi inkumbulo engcono. Yiqiniso, i-SSD enekhono ne-MLC 3D NAND izozuza kusukela kwisethi yezimpawu, kodwa kuphela uma lezi zici zibhekwa ngaphandle kwemali yedrayivu. Uma sicabangela le parameter, angiyikushiya ukuthi abanye abasebenzisi be-QLC disks bazobe bekhetha, kepha "igolide elisho" imemori ye-TLC. Futhi noma ngabe yi-SSD oyikhethayo, ngincoma ukuthi uthathe isipele sedatha ebalulekile ngokungathí sina.
