RAID 0, los yog disk striping, yuav tsum muaj tsawg kawg yog ob lub disk drives thiab nce kev ua tau zoo los ntawm ib txhij "striping" cov ntaub ntawv hla ntau disks. Windows NT Workstation ua haujlwm qhov system striping me ntsis txhim kho kuv /O kev ua tau zoo.
Ntawm no, RAID ua haujlwm li cas?
RAID ua haujlwm los ntawm kev tso cov ntaub ntawv ntawm ntau lub disks thiab tso cai rau kev nkag / tawm (I / O) kev ua haujlwm sib tshooj hauv txoj kev sib npaug, txhim kho kev ua tau zoo . Vim yog siv ntau lub disks nce lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF), khaws cov ntaub ntawv rov ua dua thiab nce txhaum cai.
Ib tug kuj yuav nug, puas yog raid nce ceev? RAID 0 yog noj ib qho ntawm cov disks thiab striping cov ntaub ntawv hla tag nrho lawv. Qhov no yuav zoo heev nce ceev , raws li koj tab tom nyeem thiab sau los ntawm ntau lub disks ib zaug. Ib cov ntaub ntawv tus kheej tuaj yeem siv tau ceev thiab muaj peev xwm ntawm tag nrho cov drives ntawm lub array.
Tom qab ntawd, ib tus tuaj yeem nug, qhov twg RAID yog qhov zoo tshaj plaws rau kev sau ntawv?
Nyob zoo Paul, the zoo tshaj raid rau kev sau ntawv yog RAID 0 raws li nws kis tau cov ntaub ntawv accrross ntau drives, downsite yog tias RAID 0 kis tau cov ntaub ntawv hla ntau lub disks, qhov tsis ua haujlwm ntawm ib lub tsav yuav rhuav tshem tag nrho cov ntaub ntawv hauv ib qho array. Qhov ntau tsav hauv ib RAID 0 array, qhov ntau dua lub caij nyoog ntawm kev tsav tsis ua haujlwm.
Puas yog RAID 0 SSD nce kev ua haujlwm?
RAID 0 ua haujlwm deb zoo dua nrog SSDs dua li nws ua nrog hard drives, vim hais tias mechanical drives tsis ceev txaus kom tau txais txiaj ntsig zoo ntawm kev nce bandwidth. Feem ntau, khiav SSDs hauv tandem ua haujlwm tiag tiag, zoo tiag tiag. Yog xav paub ntxiv txog RAID , nyeem RAID ua kom yooj yim.
