SSD vs HDD: Qhov twg yog txoj cai rau koj?

Dab tsi yog qhov txawv ntawm Ssd Thiab Hdd? Solid State Drives (SSDs) thiab Hard Disk Drives (HDDs) tuaj yeem sib koom ua ke ntawm lub cev, tab sis lawv txoj kev khaws cia cov ntaub ntawv sib txawv heev. Txhua hom tsav muaj nws qhov zoo thiab qhov tsis zoo, thiab kev txiav txim siab qhov twg haum rau koj nyob ntawm seb koj siv koj lub computer li cas. Peb phau ntawv qhia HDD vs SSD rhuav tshem kev ua haujlwm ntawm txhua hom tsav cia thiab lawv qhov cuam tshuam rau koj.

HDDs ua haujlwm li cas:

HDDs yog cov khoom siv khaws cia nyuaj uas muaj cov hlau nplaum rhiab platters, lub caj npab actuator nrog nyeem / sau taub hau, thiab lub cev muaj zog rau platter tig. Kev tswj hwm los ntawm I / O maub los thiab firmware, cov tsav no teeb tsa cov ntaub ntawv ntawm kev sib koom ua ke thiab cov haujlwm. Sau algorithms txheej txheem cov ntaub ntawv ua ntej khaws cia, tso cai rau firmware txhawm rau txheeb xyuas thiab kho qhov yuam kev. Lub preset platter ceev, xws li los ntawm 4200 mus rau 7200 rpm, hais qhov ua tau zoo ntawm cov ntaub ntawv rov qab thiab sau cov txheej txheem hauv HDDs.

Nyeem / Sau Txheej Txheem:

Txhua zaus koj thov kom lub khoos phis tawj khaws lossis hloov kho cov ntaub ntawv, I / O maub los qhia lub caj npab actuator qhov twg cov ntaub ntawv nyob, thiab nyeem / sau taub hau sau cov ntaub ntawv los ntawm kev nyeem cov nqi hauv txhua qhov chaw nyob. Yog tias qhov kev thov cuam tshuam nrog kev hloov kho cov ntaub ntawv, nyeem / sau lub taub hau hloov tus nqi ntawm cov kev cuam tshuam thiab cov haujlwm

Qhov tsis zoo:

Cov khoom siv tshuab siv rau kev nyeem ntawv thiab sau cov ntaub ntawv hauv HDDs ua rau lub sijhawm rov qab tau ntev dua piv rau cov txheej txheem hluav taws xob. Cov khoom siv tshuab raug cuam tshuam rau kev puas tsuaj yog tias ua yuam kev lossis poob, tshwj xeeb tshaj yog nyob rau hauv laptops. HDDs kuj hnyav dua thiab siv zog ntau dua piv rau Solid State Drives (SSDs).

Cov txiaj ntsig ntawm HDDs:

HDDs yog kev sim-thiab-qhov tseeb thev naus laus zis, feem ntau pheej yig dua SSDs rau tib lub peev xwm cia. Tam sim no, HDDs muab qhov chaw cia loj dua SSDs.

SSD (Solid State Drive) yog dab tsi?

SSDs ua haujlwm li cas:

SSDs siv lub cim xeeb flash, tshwj xeeb tshaj yog NAND thev naus laus zis, rau kev ua haujlwm tshwj xeeb thiab ua haujlwm ntev. Tsis zoo li HDDs, SSDs tsis muaj qhov txav mus los, ua kom muaj zog, ua haujlwm ntawm qhov kub thiab txias, thiab siv zog tsawg. Kev ua haujlwm NAND suav nrog lub rooj vag ntab-ntug transistors sau cov nqi khaws cia cov ntaub ntawv hauv daim phiaj-patterned thaiv cov qauv. SSD maub los ua lub luag haujlwm tseem ceeb hauv kev taug qab cov ntaub ntawv qhov chaw.

Nyeem / Sau Txheej Txheem:

Rau SSDs, kev hloov kho cov ntaub ntawv yog qhov nyuaj dua. Thaum twg ib feem ntawm ib qho kev hloov kho tshiab, tag nrho cov thaiv yuav tsum tau rov ua dua tshiab. Cov ntaub ntawv los ntawm cov qub thaiv yog theej mus rau ib qho thaiv sib txawv, qhov thaiv tau muab tshem tawm, thiab cov ntaub ntawv rov sau dua nrog cov kev hloov pauv rau lub block tshiab.

Thaum twg koj thov kom lub khoos phis tawj khaws lossis hloov kho cov ntaub ntawv, SSD maub los saib cov ntaub ntawv thov qhov chaw nyob thiab nyeem cov nqi them.

Thaum lub sijhawm tsis ua haujlwm, tus txheej txheem hu ua khib nyiab kom paub meej cov ntaub ntawv hauv cov ntawv qub raug tshem tawm thiab npaj rov sau dua. Kuj tseem muaj cov txheej txheem hu ua trimming, ceeb toom rau SSD nws tuaj yeem hla rov sau qee cov ntaub ntawv thaum thaiv kev tshem tawm. Qhov no yog qhov tseem ceeb heev los tiv thaiv kev hnav ntxov ntxov ntawm lub tsav, vim tias txhua qhov thaiv muaj cov lej nyeem / sau ntawv tsis kawg.

Txhawm rau txo qis kev hnav ntxiv, ib qho algorithm ua kom txhua qhov thaiv hauv lub tsav tau txais kev sib npaug ntawm cov txheej txheem nyeem / sau. Cov txheej txheem no, hu ua hnav leveling, tshwm sim tau txais thaum tus tsav ua haujlwm.

Raws li kev nyeem / sau cov txheej txheem cuam tshuam nrog cov ntaub ntawv txav, SSDs feem ntau tshaj qhov chaw cia khoom. Qee tus nqi ntawm tus tsav tsis qhia rau lub operating system thiab nkag tsis tau rau cov neeg siv. Qhov no muab qhov chaw rau tus tsav txav mus thiab tshem tawm cov khoom tsis cuam tshuam rau tag nrho cov peev txheej.

Qhov tsis zoo:

SSDs yog cov thev naus laus zis tshiab, yog li kim dua HDDs. Txawm hais tias ntes tau, nrhiav tau siab-Peev Ssds tej zaum yuav nyuaj dua piv rau HDDs. HDDs tuaj yeem muab tau txog li 2.5 npaug ntawm lub peev xwm ntawm SSDs.

Qhov zoo ntawm SSDs:

Vim li cas thiaj xaiv Solid State Drive? SSDs tuaj yeem ua kom nrawm nrawm ntawm kev ua si, kev siv, thiab tsos. Vim yog siv thev naus laus zis, SSDs sib zog dua, tiv taus kev txav mus los thiab poob zoo dua, thiab siv lub zog tsawg dua, ua rau kev ua haujlwm qis dua.

Ib qho txiaj ntsig tseem ceeb ntawm SSDs:

Puas yog lawv qhov nrawm dua piv rau HDDs. Piv txwv li, G-BONG X series, peb NVMe SSD ceev tshaj plaws, muaj kev nyeem ntawv / sau nrawm txog li 3400 / 3000MB / s. Txawm tias portable SSDs outpace HDDs. Nrog kev nyeem ntawv ceev txog 1050MB / s thiab muaj peev xwm mus txog 2TB, X8 yog 100 npaug sai dua USB flash drives thiab 7.5 npaug sai dua li cov hard drives ib txwm muaj.

Kev Txiav Txim

Qhov sib txawv ntawm hard drives thiab solid state drives yog nyob rau hauv cov cuab yeej siv los khaws thiab khaws cov ntaub ntawv. Cov lus hauv qab no qhia txog qee qhov sib txawv.

HDDs pheej yig dua thiab koj tuaj yeem tau txais ntau qhov chaw cia. Txawm li cas los xij, SSDs tau nrawm dua, sib zog dua, ruaj khov dua, thiab lawv siv zog tsawg dua. Koj cov kev xav tau yuav txiav txim seb qhov chaw khaws cia yuav ua haujlwm zoo tshaj rau koj.
