Umthamo omncaneI-SSDi-chip iyi-chip embi?Ngokwesibonelo, a128G SSDi-chip ingcono kune-a120Gchip, a256Gi-chip ingcono kune-chip ye-240G, nokunye, i-gimmick enjalo ephonswe emakethe izobangela inani elithile lesidingo.
Umthamo omkhuluI-SSDs ingahlangabezana nezidingo zethu eziningi zokugcina idatha.Uma kuqhathaniswa nabasebenzi basehhovisi, abasebenzisi bokugcina bemidlalo, umthamo omkhulu unganikeza ukusebenza okukhulu, kokubili isivinini sokufunda nokubhala kanye nesivinini sokufunda esingahleliwe esingu-4K.
Ukusebenza nokuphila isikhathi eside yikhona okuqala isidingo
Kodwa-ke, izidingo zokuthenga zomsebenzisi azikho nje kuphela kumthamo, kodwa futhi ekusebenzeni nokuphila isikhathi eside.Ukuntuleka kwamandla kuholela eqinisweni lokuthiI-SSDs ngomthamo omncane osele udinga ukusula idatha endala ngaphambi kokuthi igcwaliswe ngedatha entsha, kodwa lokhu kusebenza kuzothatha isikhathi futhi ukusula idatha kuzonciphisa impiloI-SSDkanye.(Isibonelo, imali yemakethe yamanje ye-TLC ingamelana kuphela nokususwa kwediski okugcwele okungu-3K)
Ngakho-ke, i-solid-state ibilokhu iphishekela umthamo owengeziwe, bambalwa kuphela abantu abanaka ukuthi kungani amandla okushayela okuqinile kungamandla we-Nth we-2, njengokuthi120G, 480G, 960 abanjalo.
Ezinsukwini zakudala i-Nand Flash yayiklanywe nge-2 bit ngeseli, i-Flash cell ingagcina izingcezu ezimbili zedatha, noma ngabe i-Nand Flash ithuthukiswe yaba yi-TLC kuya ku-QLC, umthamo kusengamandla e-Nth we-2.
Futhi isimo ngasinye esiqinile sizoba nesikhala esibekelwe i-OP (Over-provisioning), okuhlanganisa nendawo eyinhloko ye-OP ekhiqizwa ngokwemvelo ukuguqulwa kanambambili kanye nesikhala esengeziwe se-OP yesibili njengoba kudingeka, le ngxenye yesikhala se-OP empeleni ikhona ku-SSD, ayikwazi nje. ifundwe ngokuqondile, ibhale futhi ifinyelelwe ngumsebenzisi.
Isikhala esigodliwe se-OP sisetshenziselwa ukuthuthukisa ukusebenza kokubhala, ukunciphisa ukukhulisa ukubhala, ukuthuthukisa impilo yokubhala, nokunye ukusetshenziswa.Ngokuya ngezidingo zokusetshenziswa, abasebenzisi bangangeza mathupha isendlalelo sesithathu sesikhala se-OP.
Izindleko Ezishintshayo
Umnyombo we-solid-state drive uqukethe ikakhulukazi isilawuli esiyinhloko, imemori ye-flash ne-PCB.Umehluko kuphela phakathi kwe-240G ne-120G emakethe inani lememori ye-flash, kodwa ezindlekweni, ezimbili ze-120G kanye ne-240G eyodwa isimo esiqinile uma kuqhathaniswa ne-240G sizoba ngaphansi kwezindleko zokubiyela, ibhodi le-PCB nokulawula okuyinhloko, kodwa lokhu kungaphezulu, ingqikithi noma i-Nand Flash, ehlanganisa u-70-80% wezindleko zayo yonkeI-SSD.
Ngenqubo yamanje ye-3D enqwabelene yezendlalelo ezingu-64, umthamo wefasi elilodwa ungafinyelela ku-256Gbit (32GB), noma ngisho no-512Gbit (64GB), okusho ukuthi ukufa okumbalwa kuphela okudingekayo kumthamo ofanayo wezinhlayiya ze-flash.
Futhi ukuqinisekisa ukuthi kunenani elanele lememori ye-flash ukuze ukwazi ukufunda nokubhala ngesikhathi esifanayo, usebenzisa izinzuzo zesiteshi ukuthuthukisa ukusebenza kokufunda nokubhala, uzokhetha ibhokisi lokukala umthamo ophansi Die, yingakho umthamo omncaneAma-SSDunganciphisi izindleko ngokwandisa umthamo we-Die eyodwa.
Umthamo omkhulu awunazo lezi zinkinga, isimiso siyafana ne-RAID yethu yansuku zonke, yingakho umthamo omkhuluI-SSDukufunda nokubhala ukusebenza kunamandla.
