Qhov sib txawv ntawm cov tawv-lub xeev drives thiab cov tshuab siv tshuab nyuaj

Lub xeev ruaj khov pauv (SSDs) thiab kev nyuaj siv hluav taws xob (HDDs), raws li ob qho kev sib txawv hauv cov qauv, ua tau zoo, thiab tus nqi. Cov qauv kev sib piv hauv qab no yog ua los ntawm ntau qhov ntev xws li cov ntsiab cai qhia meej los pab cov neeg siv qhia meej txog lawv cov yam ntxwv thiab ua rau kev tshawb fawb kev tshawb fawb.
1, Core Technology Islands: Qhov tseem ceeb sib txawv ntawm Electronic Cia Thiab Cav Cia
SSD Adopts Hluav Taws Xob Lub Tshuab Cim Siab suav nrog Nand Flash nco nti, lub ntsiab tswj chip, lub ntsiab tswj chip, thiab ua yeeb yam tawm. Ntawm lawv, nand flash nco tau tuaj yeem faib ua SLC, MLC, TLC, QLC thiab lwm hom raws li chav khaws cia. Cov ntaub ntawv nyeem thiab sau cov phiajcim rau cov hluav taws xob ntawm lub xeev ntab, ua tiav cov ntaub ntawv cia hauv binary 0s thiab 1s, tag nrho tshem tawm kev kho tshuab. Ntawm qib interface, SATA SSDS tau txwv los ntawm cov kev cai, nrog nyeem ntau tshaj plaws thiab sau ceev ntawm 550mb / s; NVME SSDS xa cov ntaub ntawv los ntawm PCIie Rev tuaj yeem nyeem tau txog 7000mb / s, txhim kho cov ntaub ntawv ua tau zoo.
Hdd yog ua raws li cov tshuab kaw sib xyaw ua ke, muaj xws li ntawm kev hloov pauv nrawm nrawm nrawm ib feeb) Thaum khaws cov ntaub ntawv, lub taub hau sib nqus txav ntawm cov npoo ntawm daim disk thiab sau cov ntaub ntawv los ntawm thaj chaw muaj zog. Qhov no ua haujlwm hom nqa cov kev ua tau zoo bottencks: lub taub hau nrhiav sijhawm ntev li 5200 rpm hard drive tsuas yog kwv yees li 160mb / s. Hauv kev siv, SSDs tuaj yeem thauj khoom 10GB ua si hauv 3-5 vib nas this, thaum twg HDS noj 40-60 vib nas this, nrog kev ua tau zoo sib txawv ntawm ob.
2, Kev sib piv ua tau zoo: sib txawv hauv kev nrawm thiab ruaj khov
Nyob rau hauv lub system pib cov xwm txheej, lub sijhawm khau zaum ntawm SSD tsuas yog 8-15 vib nas this, uas yog qhov luv dua 40-90 vib nas this ntawm HDD; Thaum hloov chaw 1GB cov ntaub ntawv, nvme ssd tsuas yog siv 1-2 vib nas this, thaum hdd yuav siv li 10 vib nas this. Hais txog kev twv txiaj, SSDs tuaj yeem thauj cov games loj xws li cyberpunk {% sai dua li HDS, zam kev tos ntev ntev thiab kev lag luam. Nyob rau hauv lub ntsej muag ntawm multitasking, ssds ua tiav du hloov nrog lawv cov yam ntxwv latency qis, thaum twg HDDs yog qhov tsis muaj kev teb lub taub hau nrhiav.
3, kev pabcuam lub neej thiab kev ntseeg tau: hauv kev hnav cov vs. neeg kho tshuab hnav
Lub neej ntawm SSDs yog txwv los ntawm tus naj npawb ntawm cov lwv thiab sau cov voj voog thiab sau cov cav tov lub chips, feem ntau ntsuas hauv TBW (tag nrho cov ntawv sau ua ke). Piv txwv li, TBW ntawm 1TB TLC SSD yog kwv yees li 600tb, thiab raws li cov ntawv sau ntawm 100GB, lub theoretical purn tuaj yeem ncav cuag 16 xyoo. Kev hnav sib npaug technology ua rau hauv lub ntsiab tswj tau ncua sij hawm txuas ntxiv lub neej ntawm flash nco los ntawm kev sau cia sau cov chaw. Txawm li cas los xij, nws yuav tsum raug sau tseg tias QlC hais tias cov ntaub ntawv khaws cia ntawm tsuas yog 1 xyoos tom qab 3 xyoos), thiab tsis haum rau cov scenerarios.
Txawm hais tias HDD theoretically txhawb kev txwv tsis pub sau, nws cov tshuab kho tshuab yog cuam tshuam rau lub cev puas. Qhov kev ua tsis tiav txhua xyoo yog li 2% -5% (tsawg dua 1% rau lub taub hau kev lag luam), thiab poob peev xwm ua rau lub taub hau sib tsoo), thiab cov ntaub ntawv tsis muaj peev xwm ua rau poob qis. Txawm li cas los xij, HDD ua tau zoo nyob rau hauv kev cia khoom txias ntev, nrog cov ntaub ntawv muaj peev xwm khaws cia rau ntau tshaj 10 xyoo.
4, Xaiv Lub Tswv Yim: Scene kev yoog thiab nqi pes tsawg
Thaum nrhiav kev ua tiav qhov kawg, cov SSDs yog qhov kev xaiv zoo tshaj plaws rau cov kab ke disks, kev ua si, thiab cov software tshaj lij (xws li PS, PR) kev ua haujlwm. Lawv kuj yog tsim nyog rau lub laptop (lub zog-txuag thiab poob siab tsis zoo tsav tsheb, thiab suab nrov ua suab nrov hauv tsev thiab cov vis dis aus. HDD, nrog nws lub peev xwm loj thiab tus nqi ua nqi qis dua rau cov ntaub ntawv backup thiab kev soj ntsuam cov nyiaj siv nyiaj txiag tsawg kawg ntawm cov khoom siv khoom lag luam nthuav dav.
5, Kev Siv Kev Siv: Lub Pit Zam cov kev qhia thiab kev ua kom ua tau zoo
Thaum xaiv SSDs, tlc cov khoom lag luam granular yuav tsum tau muab qhov tseem ceeb rau 4k random tau zoo dua li 30k random tau zoo dua li 30k random Thaum siv HDD, cov khoom lag luam xws li seabain galaxy series yog qhov haum rau kev ua kom zoo li NAS lossis cov chaw ua haujlwm, thaum chaw taws teeb txee) kom ntseeg tau tias cov ntaub ntawv muaj kev ruaj ntseg.
