Lub xeev-xeev hard disk los yog SSD tsav yog qhov ceev ceev ntawm ib qho tawv disk rau koj lub computer. Los ntawm kuv tus kheej, kuv nco ntsoov tias thaum koj tsis ua haujlwm hauv lub computer, qhov chaw SSD yog qhov nruab (lossis zoo dua, qhov tsuas), koj yuav tsis nkag siab txog qhov "ceev" nyob rau tom qab, nws yog qhov zoo kawg li. Cov tshooj no yog cov ncauj lus tseem ceeb, tab sis raws li ib tus neeg siv novice, peb tham txog seb qhov SSD yog qhov twg thiab yog tias koj xav tau. Saib tseem: Tsib yam uas yuav tsum tsis txhob ua tiav nrog SSD mus ntev lawv txoj sia
Nyob rau hauv xyoo tas los, SSD drives ua neeg pheej yig thiab pheej yig dua. Txawm li cas los xij, thaum lawv tseem pheej kim tshaj cov tshuaj HDDs. Yog li, SSD yog dab tsi, qhov zoo ntawm kev siv nws, yuav ua li cas ua haujlwm nrog SSD txawv ntawm HDD?
Dab tsi yog lub xeev-state hard drive?
Feem ntau, cov cuab yeej siv ntawm solid-state hard drives yog qub heev. Cov SSDs tau nyob hauv kev ua lag luam nyob rau hauv ntau cov ntaub ntawv tau ntau xyoo lawm. Qhov ntxov tshaj plaws ntawm lawv tau raws li RAM nco thiab tsuas yog siv nyob rau hauv lub feem ntau kim thiab super computers. Nyob rau hauv 90s, SSDs le flash nco tau tshwm sim, tab sis lawv cov nqi tsis pub nkag mus rau hauv lub khw cov neeg siv, yog li cov tsav tsheb no tau paub tshwj xeeb tshaj yog rau cov kws khomob hauv Tebchaws Meskas. Thaum xyoo 2000s, tus nqi ntawm flash nco tseem poob, thiab qhov kawg ntawm lub xyoo caum, SSDs pib tshwm hauv cov tshuab computer zoo tib yam.
