Hybrid Drive vs SSD
Ib tug yuav tsum nkag siab qhov sib txawv ntawm Hybrid Drive thiab SSD los ntawm qhov taw tes tias hybrid disk muaj cov khoom siv hluav taws xob thiab cov khoom hauv lub xeev disk. Conventionally hard disks yog cov cuab yeej siv tshuab uas khaws cov ntaub ntawv ntawm cov hlau nplaum sib nqus siv lub taub hau tshuab uas tig. Cov ntaub ntawv khaws cia tshiab yog Solid State Drives (SSD), uas tsis muaj cov khoom siv tshuab, tab sis tsuas yog hluav taws xob circuits xwb. SSDs muaj cov txiaj ntsig zoo xws li kev kub ceev, kev nkag tau sai dua, siv hluav taws xob tsawg dua, me me, thiab tsis muaj suab thaum ua haujlwm. Tab sis qhov tsis zoo yog tus nqi. Tus nqi ntawm 128 GB SSD yog siab dua tus nqi ntawm 1 TB txhua yam disk. Yog li niaj hnub no, txhawm rau rho tawm qhov zoo ntawm ob hom disks, hom tshiab hard disk tau tsim hu ua hybrid disk. Nws muaj ib tug loj mechanical disk ntxiv rau me me SSD. Ntawm no, SSD ua raws li lub cache rau feem ntau cov ntaub ntawv nkag. Lub hybrid disk yuav muab lub peev xwm loj ntawm tus nqi tsawg dua li SSD tab sis muab qhov kev ua tau zoo dua li cov khoom siv sib xyaw ua ke.
SSD yog dab tsi?
SSD uas sawv cev rau Solid State Drive yog qhov tseeb hard disk thev naus laus zis uas tab tom txhim kho sai hauv lub sijhawm no. Raws li lub npe nws tus kheej qhia, cov disks tsis muaj cov khoom siv tshuab. Cov ntaub ntawv yog khaws cia rau hauv kev sib xyaw ua ke. Piv txwv li, niaj hnub SSD disks feem ntau siv NAND-based flash nco uas tuaj yeem khaws cov ntaub ntawv mus tas li yam tsis muaj hwj chim. Yog li, SSD zoo li lub flash drive nrog lub peev xwm loj. Qhov zoo tshaj plaws ntawm SSD yog tias, raws li kev nyeem ntawv thiab sau ntawv ua haujlwm yog cov khoom siv hluav taws xob tag nrho, kev ua tau zoo heev. Yog li, qhov latency nkag mus rau cov ntaub ntawv yuav tsawg heev, thiab yog li ntawd, lub operating system thiab software ntawm SSD yuav khiav sai dua. Tsis tas li ntawd, kev nyeem / sau dhau ntawm SSD nrawm dua; yog li koj yuav tau luam cov ntaub ntawv loj hauv vib nas this. Tsis tas li ntawd, SSDs muaj kev tiv thaiv ntau dua rau kev co thiab kev poob siab vim tsis muaj cov khoom siv tshuab koom nrog. Qhov loj ntawm SSD kuj tsawg heev, thiab yuav tsis muaj suab nrov thaum nkag mus rau lub disk. Kev siv hluav taws xob kuj yuav tsawg. Tab sis qhov teeb meem nrog SSD yog nws tus nqi. Txawm tias 128 GB SSD disk yuav siab dua tus nqi ntawm 1 TB txhua yam disk.
Hybrid Drive yog dab tsi?
Ib lub hybrid tsav yog lub hard disk uas yog tsim los ntawm ob qho tib si cov khoom siv hluav taws xob thiab cov khoom hauv xeev disks (SSD). Ib qho yooj yim mechanical hard drive yog ib lub disk uas khaws cov ntaub ntawv ntawm cov hlau nplaum hlau nplaum uas tau nyeem los ntawm lub taub hau hlau nplaum uas txav tau siv cov motors. Ib Lub Xeev Hard Drive (SSD) yog ib qho disk uas tsis muaj cov khoom siv kho tshuab qhov twg cov ntaub ntawv khaws cia tshwm sim siv cov kev sib xyaw ua ke. Ib tug hybrid Drive muaj ob qho no: ib tug neeg kho tshuab hard disk ntxiv rau SSD. Mechanical hard disks yog tus nqi qis thiab lawv lub peev xwm loj heev. Tab sis, SSDs tseem tsis tau muaj nqi ntau thiab lawv lub peev xwm kuj me me. Tab sis qhov teeb meem nrog cov neeg kho tshuab disks yog tias, lawv qeeb qeeb dua thaum piv rau SSDs. Hauv cov cuab yeej siv tshuab, cov ntaub ntawv hloov tau yooj yim yog tsawg heev thaum piv rau SSDs. Tsis tas li ntawd, latency yog siab thaum piv rau SSD. Raws li ob qho tib si muaj nws tus kheej qhov zoo thiab qhov tsis zoo, hybrid tsav tau qhia kom txaus siab rau lub disk sai dua li cov neeg kho tshuab disk tab sis nrog tus nqi qis dua SSD.
Nyob rau hauv ib lub hybrid hard disk, thaum lub tshuab disk muaj peev xwm nyob ib ncig ntawm ib terabyte, qhov loj ntawm SSD, yog nyob ib ncig ntawm 64 GB. Ntawm no, SSD ua lub cache rau cov neeg kho tshuab hard disk. Qhov ntawd feem ntau nkag mus rau cov ntaub ntawv yuav raug coj mus rau hauv SSD kom lawv nkag tau sai dua. Yog li, twv yuav raug hu, cov ntaub ntawv kev khiav hauj lwm uas ib txwm nkag mus yuav raug coj mus rau SSD thiab hauv hybrid disk ib qho tuaj yeem txaus siab rau qhov kev ua tau zoo dua qub thaum piv rau cov khoom siv kho tshuab ib txwm muaj.
Qhov txawv ntawm Hybrid Drive thiab SSD yog dab tsi?
• Ib tug hybrid disk muaj ib tug neeg kho tshuab hard disk thiab ib tug Solid State Disk (SSD). SSD yog SSD ntshiab.
• Ib qho hybrid disk muaj cov khoom siv kho tshuab koom nrog vim tias muaj cov khoom siv hluav taws xob sab hauv. Tab sis, SSD tsis muaj cov khoom siv tshuab tab sis tsuas yog cov khoom siv hluav taws xob xwb.
• Tus nqi ntawm SSD yog siab dua tus nqi ntawm hybrid disk.
• Kev ua tau zoo ntawm SSD (latency thiab kev nyeem / sau nrawm) yuav siab dua qhov ua tau los ntawm hybrid disk.
• Lub peev xwm ntawm hybrid disks yog qhov loj vim nws suav nrog cov khoom siv sib xyaw ua ke. Tab sis lub peev xwm ntawm SSD feem ntau yog me me.
• Kev siv hluav taws xob ntawm SSD tsawg dua qhov kev siv hluav taws xob ntawm hybrid disk.
• Thaum lub sijhawm ua haujlwm ntawm hybrid disk, yuav muaj suab nrov los ntawm kev txav mus los. Tab sis SSD yuav tsis muaj suab thaum ua haujlwm.
Summary:
Hybrid Drive vs SSD
SSD tsis muaj cov khoom siv tshuab txhua. Lawv yog hom ceev tshaj plaws tab sis tus nqi siab thiab lub peev xwm tsawg. Ib tug hybrid disk muaj ib tug me me peev xwm SSD nrog ib tug loj muaj peev xwm pa mechanical disk. Lub SSD ua raws li lub cache rau cov ntaub ntawv hauv disk thiab yog li qhov kev ua tau zoo ntawm hybrid disk yuav siab dua li lub tshuab disk. Tsis tas li ntawd, raws li lub peev xwm ntawm cov neeg kho tshuab disk hauv hybrid disk loj, yuav muaj chaw txaus rau koj cov ntaub ntawv loj. Yog tias xav tau kev ua tau zoo tshaj plaws, ib tus yuav tsum mus rau SSD. Tab sis, yog tias ib tus neeg muaj peev nyiaj tsawg tab sis xav tau lub disk nrog lub peev xwm loj dua li cov khoom siv hluav taws xob zoo sib xws thiab kev ua haujlwm zoo dua li cov khoom siv hluav taws xob, ces siv cov hybrid disk.
