Qhov sib txawv ntawm SSD thiab HDD rau Kev Khaws Cov Ntaub Ntawv
Hauv lub ntiaj teb ntawm cov khoos phis tawj thiab cov khoom siv digital, kev khaws cov ntaub ntawv yog ib qho tseem ceeb tshaj plaws. Ob hom khoom siv khaws cia uas siv niaj hnub no yog HDD (Hard Disk Drive) thiab SSD (Solid State Drive). Ob qho tib si ua haujlwm tib lub hom phiaj - khaws cov operating system, cov ntawv thov, thiab cov ntaub ntawv - tab sis ua haujlwm sib txawv heev. Cov kev sib txawv no hauv lawv txoj kev ua haujlwm cuam tshuam rau qhov ceev, kev ruaj khov, tus nqi, thiab txawm tias kev paub txhua hnub ntawm tus neeg siv. Tsab xov xwm no piav qhia meej txog qhov sib txawv ntawm SSD thiab HDD kom koj tuaj yeem ua qhov kev xaiv zoo tshaj plaws.
1. Nws Ua Haujlwm Li Cas: Mechanical vs Electronic
Qhov sib txawv tseem ceeb tshaj plaws ntawm HDD thiab SSD yog nyob rau hauv lawv cov thev naus laus zis cia khoom.
Lub hard disk drive (HDD) yog ib lub cuab yeej khaws cia khoom siv tshuab. Nws muaj cov platters tig ceev ceev thiab lub taub hau nyeem/sau uas nyeem lossis sau cov ntaub ntawv. Vim tias nws vam khom cov khoom txav mus los, HDDs muaj kev txwv hauv kev ceev thiab yooj yim rau kev poob siab.
Lub caij no, SSDs ua haujlwm hauv hluav taws xob siv cov chips nco flash (NAND). Tsis muaj qhov chaw txav mus los. Cov ntaub ntawv khaws cia thiab nkag mus los ntawm cov hluav taws xob circuits, ua rau kev nyeem / sau ceev dua thiab ruaj khov dua nyob rau hauv ntau yam xwm txheej.
2. Ceev: SSD Zoo Dua
Yog tias koj xav tau qhov kev txhim kho kev ua tau zoo tshaj plaws ntawm koj lub khoos phis tawj, hloov ntawm HDD mus rau SSD feem ntau yog qhov kev txav zoo tshaj plaws.
- Cov HDD muaj qhov nyeem/sau qeeb dua vim lawv yuav tsum tos kom cov platters tig thiab cov taub hau txav mus rau qhov chaw ntawm cov ntaub ntawv. Qhov ceev no kuj raug cuam tshuam los ntawm kev sib cais ntawm cov ntaub ntawv.
- SSDs muab kev nkag mus rau cov ntaub ntawv sai heev vim tias lawv tuaj yeem khaws cov ntaub ntawv ncaj qha yam tsis muaj kev txav mus los.
Hauv kev siv txhua hnub, SSDs ua rau:
- lub sijhawm khau raj ntawm lub operating system luv dua,
– cov ntawv thov qhib sai dua,
- cov txheej txheem ntawm kev theej cov ntaub ntawv loj dua ua haujlwm tau zoo dua,
- kev ua haujlwm ntau yam du thiab yooj yim dua.
Txawm tias rau cov dej num me me xws li qhib browser lossis cov ntaub ntawv ua haujlwm, qhov sib txawv tuaj yeem tseem ceeb heev.
3. Peev Xwm Cia Khoom: HDD Loj Dua Ntawm Tus Nqi Pheej Yig
Hais txog qhov muaj peev xwm, HDDs feem ntau tseem ua tau zoo tshaj plaws hauv "kev cia khoom loj rau ib duas las".
- Cov HDD muaj nyob rau hauv cov peev xwm loj xws li 1TB, 2TB, 4TB, thiab siab dua ntawm tus nqi pheej yig.
- SSDs kuj muaj nyob rau hauv cov peev xwm loj, tab sis lawv feem ntau kim dua HDDs rau tib lub peev xwm.
Yog li ntawd, cov neeg uas xav tau qhov chaw loj rau cov duab, cov yeeb yaj kiab, lossis cov thaub qab feem ntau xaiv HDDs, tshwj xeeb tshaj yog thaum kev ua haujlwm siab tsis yog qhov yuav tsum tau ua.
4. Nqe: SSDs kim dua, tab sis sib tw ntau dua
Tus nqi sib txawv ntawm SSD thiab HDD yav tas los loj heev, tab sis tam sim no nws ze zuj zus lawm.
- HDDs feem ntau pheej yig dua, tsim nyog rau cov kab ke uas muaj peev nyiaj tsawg lossis xav tau chaw cia khoom ntau.
- SSDs tseem kim dua, tab sis kev txo nqi ua rau lawv yooj yim dua, tshwj xeeb tshaj yog nyob rau hauv cov peev xwm siv dav dav ntawm 256GB, 512GB, thiab txawm tias 1TB.
Feem ntau, kev sib xyaw ua ke ntawm SSD me me rau lub operating system thiab cov ntawv thov, ntxiv rau HDD loj rau kev khaws cov ntaub ntawv, yog qhov kev daws teeb meem pheej yig tshaj plaws.
5. Kev Ruaj Khov thiab Kev Ruaj Ntseg ntawm Cov Ntaub Ntawv: SSDs Muaj Kev Tiv Thaiv Kev Poob Siab Ntau Dua
Vim tias HDD muaj cov khoom siv kho tshuab, lawv yooj yim raug rau:
- kev cuam tshuam,
- kev co,
- poob,
- hloov chaw thaum lub disk ua haujlwm.
Yog tias lub laptop poob thaum lub HDD tseem ua haujlwm, qhov kev pheej hmoo ntawm kev puas tsuaj rau lub cev thiab kev poob cov ntaub ntawv yuav nce ntxiv.
Cov SSDs tiv taus kev co ntau dua vim lawv tsis muaj qhov txav mus los. Qhov no ua rau lawv yog qhov kev xaiv zoo dua rau cov laptops, cov khoom siv mobile, lossis cov neeg siv uas mus ncig ntau zaus.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias SSDs kuj muaj lub neej luv luv, tshwj xeeb tshaj yog hais txog kev sau ntawv. Txawm li ntawd los, SSDs niaj hnub no feem ntau muaj lub zog txaus kom siv tau ntau xyoo ntawm kev siv ib txwm.
6. Kev Siv Hluav Taws Xob thiab Kub: SSDs Zoo Dua
Feem ntau SSDs siv hluav taws xob tau zoo dua li HDDs. Qhov no muaj ntau yam zoo:
- Lub roj teeb laptop tuaj yeem siv tau ntev dua,
- qhov kub ntawm lub cuab yeej feem ntau qis dua,
- lub kaw lus ntsiag to dua vim tias tsis muaj suab ntawm lub disc tig.
Qhov sib piv, HDDs xav tau lub zog los tig cov platters thiab txav cov taub hau, thiab tuaj yeem tsim cov suab nrov me me xws li humming lossis clicking, tshwj xeeb tshaj yog thaum muaj kev thauj khoom hnyav.
7. Suab nrov: HDD tuaj yeem hnov, SSD ntsiag to
Yog koj ua tib zoo mloog cov suab hauv computer, cov HDD feem ntau ua rau:
- lub suab tig (spindle),
- suab nrov taub hau thaum nyeem/sau cov ntaub ntawv.
SSDs ntsiag to vim lawv ua haujlwm hluav taws xob tag nrho. Rau cov neeg siv uas xav tau lub khoos phis tawj ntsiag to - piv txwv li, hauv chav kaw suab, chaw ua haujlwm ntsiag to, lossis siv thaum hmo ntuj - SSD yog qhov zoo tagnrho.
8. Kev tawg ua feem thiab kev saib xyuas: HDDs raug cuam tshuam ntau dua
Hauv HDDs, cov ntaub ntawv tuaj yeem tawg thoob plaws ntau qhov chaw ntawm lub platter (fragmentation). Qhov no ua rau lub sijhawm nkag mus ntev dua vim tias cov taub hau yuav tsum txav mus deb dua. Yog li ntawd, HDDs feem ntau raug kho kom zoo dua nrog defragmentation (txawm hais tias qhov no feem ntau yog automated ntawm cov txheej txheem niaj hnub).
Cov SSDs tsis muaj kev sib cais zoo ib yam, thiab qhov tseeb tsis pom zoo kom defragmentation vim tias nws tuaj yeem ntxiv cov voj voog sau tsis tsim nyog. SSDs siv cov txheej txheem xws li kev hnav leveling los tswj kev faib tawm ntawm cov ntaub ntawv sau, ua kom lub zog tsav ntev dua.
9. Hom thiab Daim Ntawv Qhia: SSDs Muaj Kev Ywj Pheej Ntau Dua
Feem ntau cov HDD muaj ntau qhov loj me:
– 3.5 nti (desktop),
– 2.5 nti (lub laptop).
SSDs muaj ntau hom sib txawv:
- 2.5 nti SATA (zoo ib yam li laptop HDD),
– M.2 SATA,
- M.2 NVMe (ceev tshaj plaws, siv PCIe txoj kab).
NVMe SSDs tshwj xeeb muab kev ua tau zoo dua li SATA, ua rau lawv zoo tagnrho rau cov haujlwm nyuaj xws li kev kho video, kev tsim duab, kev sau cov lej, lossis kev ua si niaj hnub.
10. Thaum twg koj yuav tsum xaiv SSD lossis HDD?
Yuav kom yooj yim txiav txim siab, ntawm no yog cov lus qhia raws li koj cov kev xav tau:
Xaiv SSD yog tias:
- Koj xav kom koj lub computer/laptop zoo li ceev thiab teb tau sai.
- Koj feem ntau qhib ntau daim ntawv thov lossis ua ntau yam haujlwm tib lub sijhawm.
- Koj xav tau kev ceev rau kev kho, kev ua si, lossis kev ua haujlwm tshaj lij.
– Koj feem ntau nqa koj lub laptop thiab xav kom nws tsis txhob poob siab.
Xaiv HDD yog tias:
– Koj xav tau lub peev xwm loj nrog rau cov peev nyiaj tsawg.
- Koj xav khaws cov ntaub ntawv khaws cia, cov ntaub ntawv thaub qab, lossis cov ntaub ntawv xov xwm.
- Kev ceev tsis yog qhov tseem ceeb tshaj plaws.
Xaiv qhov kev sib xyaw ua ke ntawm SSD + HDD yog tias:
- Koj xav tau kev ua haujlwm siab thiab qhov chaw cia khoom loj.
- Koj tuaj yeem nruab ob lub drives (piv txwv li SSD rau lub system thiab HDD rau cov ntaub ntawv).
Xaus
SSDs thiab HDDs ob leeg ua lub luag haujlwm tseem ceeb ua cov ntaub ntawv khaws cia, tab sis lawv muaj cov yam ntxwv sib txawv. SSDs zoo heev hauv kev ceev, kev siv hluav taws xob zoo, thiab kev tiv thaiv kev poob siab, thaum HDDs muaj peev xwm loj dua ntawm tus nqi pheej yig dua. Kev xaiv ntawm ob qho no nyob ntawm koj cov kev xav tau: seb koj puas muab qhov tseem ceeb rau kev ua tau zoo lossis lub peev xwm. Rau ntau tus neeg siv, txoj hauv kev zoo tshaj plaws yog siv SSD rau lub operating system thiab cov ntawv thov tseem ceeb, tom qab ntawd ntxiv HDD rau kev khaws cov ntaub ntawv loj.
Yog tias koj xav tau, kuv kuj tuaj yeem tsim ib qho version ntawm tsab xov xwm no (uas suav nrog NVMe, IOPS, TBW, thiab SMART) lossis ib qho version yooj yim dua rau cov neeg nyeem tshiab.
