Kev Siv Tshuab SSD Hauv Cov Khoos Phis Tawj Rau Kev Kub Ceev
Pengantar
Nyob rau lub caij nyoog niaj hnub no, qhov xav tau kev ceev thiab kev ua haujlwm zoo hauv kev siv computer tab tom nce ntxiv. Ib qho uas ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab txog kev ua haujlwm ntawm lub computer yog cov ntaub ntawv khaws cia. Cov Khoom Siv Kho Vajtse (SSDs) yog ib qho thev naus laus zis uas tam sim no tau hloov cov hard disk drives (HDDs) ib txwm muaj hauv ntau lub computer systems vim lawv muaj kev ceev thiab kev ua tau zoo dua. Tsab xov xwm no yuav saib tob txog SSD thev naus laus zis, vim li cas nws thiaj li tseem ceeb rau kev ceev ceev, thiab nws tuaj yeem cuam tshuam li cas rau kev paub ntawm tus neeg siv tag nrho.
Keeb Kwm thiab Kev Loj Hlob ntawm SSD
Ua ntej, cia peb rov los saib dua keeb kwm thiab kev loj hlob ntawm SSDs. SSDs thawj zaug tshwm sim thaum xyoo 1970s thiab xyoo 1980s thaum ntxov ua lwm txoj hauv kev khaws cia rau cov kev siv hauv kev lag luam thiab tub rog. Txawm li cas los xij, thaum xub thawj, vim lawv tus nqi siab, SSDs tsis tau siv dav hauv kev lag luam.
Txij li xyoo 2000s, nrog kev nce qib hauv kev siv tshuab semiconductor thiab cov nqi khoom poob qis, SSDs tau dhau los ua qhov kev xaiv zoo dua rau cov neeg siv khoom loj. Cov tuam txhab xws li Intel, Samsung, thiab Kingston tau pib tsim cov SSDs pheej yig dua thiab ua haujlwm tau zoo dua, ua rau cov thev naus laus zis nkag tau yooj yim dua thiab nrov dua. Niaj hnub no, SSDs tau dhau los ua tus qauv hauv ntau lub cuab yeej, los ntawm laptops thiab desktop PCs mus rau cov server systems uas xav tau kev ceev ceev.
Qhov Txawv Tseem Ceeb ntawm SSD thiab HDD
Tsis zoo li HDDs, uas siv cov platters tig thiab cov taub hau nyeem/sau, SSDs khaws cov ntaub ntawv hauv NAND flash memory chips. Qhov no txhais tau tias SSDs tsis muaj qhov txav mus los, ua rau lawv ceev dua, ruaj khov dua, thiab ruaj khov dua. Cia peb saib qee qhov tseem ceeb uas sib txawv SSDs thiab HDDs:
1. Kev Nyeem/Sau Ceev: SSDs muaj peev xwm nyeem/sau ceev dua li HDDs. Kev nyeem ceev ntawm SSD feem ntau yog li ntawm 500 txog 550 MB/s, thaum HDDs feem ntau tsuas yog ncav cuag 100 txog 150 MB/s xwb.
2. Latency: Latency yog lub sijhawm uas nws siv rau qhov chaw cia khoom kom pib xa cov ntaub ntawv tom qab tau txais kev thov. SSDs muaj latency qis dua (nruab nrab 0.1 ms) dua li HDDs (nruab nrab 5-10 ms), uas txhais tau tias SSDs tuaj yeem ua tiav ntau cov haujlwm nkag / tso zis ib ob (IOPS).
3. Kev Ruaj Khov: Vim tias tsis muaj cov khoom txav mus los, SSDs tiv taus kev co ntawm lub cev uas feem ntau tuaj yeem ua rau HDDs puas tsuaj.
4. Kev Siv Hluav Taws Xob Zoo: Feem ntau SSDs siv hluav taws xob tsawg dua li HDDs, ua rau lawv siv hluav taws xob zoo dua, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv nqa tau xws li laptops.
Hom SSDs thiab Cov Txuj Ci Txhawb Nqa
Cov SSD muaj ntau hom thiab ntau yam qauv. Nov yog qee hom SSD tseem ceeb uas feem ntau siv:
1. SATA SSD: Qhov no yog thawj hom SSD uas cov neeg siv khoom siv dav dav. Ua haujlwm ntawm SATA interface, SSD no muaj qhov ceev tshaj plaws txog li 600 MB / s. Txawm hais tias ceev dua HDDs, SATA SSDs qeeb dua li SSDs tshiab.
2. NVMe SSD (Non-Volatile Memory Express): NVMe yog ib qho chaw cia khoom uas tsim tshwj xeeb rau SSDs, siv PCIe (Peripheral Component Interconnect Express) txoj kab kom muaj kev nyeem/sau ceev dua (txog li 3500 MB/s thiab siab dua).
3. M.2 SSD: M.2 yog ib daim ntawv uas txhawb nqa ntau yam interfaces, suav nrog SATA thiab NVMe. M.2 SSDs me dua thiab tuaj yeem ntsia ncaj qha rau ntawm lub motherboard, muab qhov tsos huv dua thiab ua kom muaj chaw ntau tshaj plaws hauv lub computer.
4. U.2 SSD: Lub SSD no siv lub qhov txuas U.2 thiab feem ntau pom muaj nyob rau hauv cov servers lossis chaw ua haujlwm siab uas xav tau kev ua haujlwm siab heev.
Cov txiaj ntsig ntawm kev siv SSD hauv cov khoos phis tawj
Kev siv SSD hauv kev teeb tsa lub khoos phis tawj coj ntau yam zoo uas tuaj yeem txhim kho kev ua tau zoo thiab kev siv neeg siv:
1. Kev Khau raj sai dua: SSDs tuaj yeem txhim kho lub sijhawm khau raj ntawm lub operating system los ntawm ob peb feeb (nrog HDDs) mus rau ob peb feeb xwb. Cov neeg siv tsis tas yuav tos ntev rau lawv cov khoos phis tawj kom npaj siv.
2. Kev Thauj Khoom Siv Daim Ntawv Thov: Cov ntawv thov hnyav xws li software kho video, tsim duab, thiab ua si yuav thauj khoom sai dua, ua rau kev ua haujlwm tsim tau zoo dua thiab kev paub txog kev ua si.
3. Kev Hloov Cov Ntaub Ntawv: Kev tsiv cov ntaub ntawv los ntawm ib daim nplaub tshev mus rau lwm qhov yog qhov ceev dua, muaj txiaj ntsig zoo thaum tuav cov ntaub ntawv loj.
4. Kev Siv Ua Haujlwm Ntau Yam: SSDs tso cai rau lub kaw lus los tswj kev ua haujlwm ntau yam zoo dua yam tsis muaj kev ua haujlwm qeeb qeeb.
Kev cuam tshuam ntawm SSD rau lwm cov lag luam
Sib nrug ntawm kev siv rau hauv cov khoos phis tawj thiab laptops, SSDs kuj muaj qhov cuam tshuam zoo rau ntau yam kev lag luam xws li:
1. Cov Servers thiab Cov Chaw Khaws Cov Ntaub Ntawv: SSDs ua rau cov servers thiab cov chaw khaws cov ntaub ntawv tuaj yeem tswj hwm ntau qhov kev thov ntawm qhov ceev dua thiab nrog qis dua latency. Qhov no yog qhov tseem ceeb rau cov ntawv thov xws li lub vev xaib hosting, cov ntaub ntawv loj, thiab kev suav huab.
2. Kev Lag Luam Muaj Tswv Yim: Kev kho cov yeeb yaj kiab, 3D animation, thiab lwm yam kev siv tsim qauv xav tau kev nkag mus rau cov ntaub ntawv sai sai kom ua haujlwm nrog cov ntaub ntawv loj. SSDs ua tau raws li qhov xav tau no zoo kawg nkaus, ua rau muaj kev ua haujlwm zoo dua.
3. Kev Ua Si: Hauv kev lag luam kev ua si, kev nkag mus rau cov ntaub ntawv ceev yog qhov tseem ceeb heev los txo lub sijhawm thauj khoom, kev hais lus tsis meej, thiab txhim kho qhov kev paub txog kev ua si tag nrho.
4. Kev Sau Cov Software: Cov neeg sau cov program yuav muaj kev ceev dua thaum lub sijhawm sau cov code vim tias SSD tuaj yeem nyeem thiab sau cov ntaub ntawv xav tau sai.
Cov Teeb Meem thiab Yav Tom Ntej ntawm SSDs
Txawm hais tias muaj ntau yam zoo, SSDs kuj muaj qee qhov teeb meem. Ib qho ntawm cov no yog tus nqi siab dua ib GB piv rau HDDs. Txawm li cas los xij, tus nqi SSD tau pom tias poob qis heev, ua rau lawv pheej yig dua dhau sijhawm.
Tsis tas li ntawd xwb, tseem muaj teeb meem ntawm qhov ruaj khov ntawm lub cim xeeb flash siv hauv SSDs. Txhua lub cell nco hauv NAND chip muaj qee qhov kev nyeem / sau ua ntej nws ua tsis tiav. Txawm li cas los xij, cov thev naus laus zis xws li kev hnav leveling thiab kev kho qhov yuam kev tau tsim los txuas ntxiv lub neej ntawm SSDs.
Yav tom ntej ntawm SSDs yog qhov ci ntsa iab, nrog rau kev tshawb fawb thiab kev txhim kho tas mus li los txhim kho kev ua tau zoo, peev xwm, thiab kev ntseeg tau. Cov thev naus laus zis tshiab, xws li 3D NAND thiab QLC (Quad-Level Cell), muab peev xwm ntau dua ntawm tus nqi qis dua.
Xaus
Cov thev naus laus zis SSD tau dhau los ua qhov kev xaiv tus qauv rau cov neeg siv uas tab tom nrhiav kev ceev ceev thiab kev ua haujlwm zoo tshaj plaws hauv lawv lub khoos phis tawj. Nrog ntau hom thiab cov qauv muaj, cov neeg siv tuaj yeem xaiv SSD uas haum rau lawv cov kev xav tau zoo tshaj plaws. Qhov ceev, kev ruaj khov, thiab kev siv hluav taws xob zoo uas SSDs muab ua rau lawv yog ib qho tseem ceeb hauv kev siv thev naus laus zis computer niaj hnub no. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev pheej yig ntawm SSDs, yav tom ntej ntawm kev khaws cov ntaub ntawv digital zoo li muaj kev cia siab heev.
