SSD kev faib tawm

Txoj kev faib:
SSD cia media tau muab faib ua ob hom, ib qho yog siv Flash nco (flash chip) raws li kev kaw khoom nruab nrab, thiab lwm qhov kev siv yeeb yam khoom muaj nruab nrab. Qhov tseeb yog Intel's XAPhoin Particlecthuab thev naus laus zis.
SSD raws Flash lub cim xeeb:
SSD raws Flash nco (Immeflash Disk, Serial ATA Flash Disk): siv Flash nti li SSD. Nws cov tsos tuaj yeem ua rau ntau yam qauv, xws li: phau ntawv Hard disk, micro hard disk, daim npav nco, USB flash drive thiab lwm yam qauv. Qhov zoo tshaj plaws kom zoo dua ntawm SSD cov chaw tsav tsheb no yog tias nws tuaj yeem hloov mus, thiab cov ntaub ntawv tiv thaiv tsis yog tswj hwm los ntawm cov khoom siv fais fab. Nws tuaj yeem hloov kho rau ntau qhov chaw thiab haum rau cov neeg siv khoom. Lub neej ntev, nyob ntawm sib txawv flash nco xov. SLC nco feem ntau txog kaum tawm txhiab tus PE, MLC tuaj yeem ncav ntau dua 3,000 zaus, thiab QLC tshiab tuaj yeem ua kom muaj lub neej 300 lub sijhawm. Cov neeg siv txhua xyoo ntawm cov neeg siv dog dig tsis tshaj 50 zaug rau tag nrho cov loj ntawm lub hard disk. Txawm tias cov pheej yig QLC flash nco tau tuaj yeem muab lub neej sau ntawm 6 xyoo. Kev ntseeg siab, cov tsev zoo tsev SSDs tuaj yeem yooj yim ua tiav ib feem kaum qhov kev ua tsis tiav hauv tsev neeg siv hluav taws xob nyuaj.
Raws li DRAM:
Dram-based ssds: Siv ua yeeb yam ua kom haum raws li qhov nruab nrab, thiab muaj qhov nqaim ntawm cov ntawv thov. Nws qog cov qauv tsim ntawm cov cuab yeej nyuaj cov ntaub ntawv, siv tau cov khoom lag luam pci thiab kev tswj hwm kev lag luam pci thiab FC cuam tshuam rau kev sib txuas rau cov tswv lossis servers. Daim ntawv thov cov kev thov tuaj yeem faib ua ob hom: SSD hard disks thiab SSD hard disk arrays. Nws yog qhov kev ua tau zoo siab uas tuaj yeem sau tau infinitely, tab sis tsuas yog drawback yog tias nws yuav tsum muaj kev ywj pheej tiv thaiv los tiv thaiv cov ntaub ntawv kev ruaj ntseg. Dram cov khoom siv-thoob plaws hauv lub xeev tsis yog cov khoom siv tsis yog cov khoom siv.
Raws li 3D xoint
3D sampoint-based ssds: hauv txoj ntsiab cai, lawv nyob ze kom ua kom zoo, tab sis lawv tsis yog volatile cia. Qhov kev nyeem latency yog tsawg heev, uas tau yooj yim tshaj plaws ib feem pua ntawm cov SSDs uas twb muaj lawm, thiab muaj ze li ntawm lub neej tsis muaj. Qhov tsis zoo yog tias qhov ceev yog qhov tsis tshua muaj piv rau Nand, tus nqi yog qhov ntau heev, thiab feem ntau yog siv rau hauv kub taub hau thiab cov ntaub ntawv.
