Thaum xaiv cov khoom ruaj khov lub xeev SSD rau kev siv hauv tsev, koj tuaj yeem hla tus yam ntxwv xws li hom kev nco tau siv thiab xav paub qhov twg yog qhov zoo dua - MLC lossis TLC (koj kuj tseem yuav nrhiav lwm txoj kev xaiv rau kev tsim lub cim xeeb, piv txwv li V-NAND lossis 3D NAND ) Kuj tseem nyuam qhuav pom muaj nqis txaus nyiam nrog QLC lub cim xeeb.
Hauv qhov kev tshuaj xyuas no rau cov neeg pib tshiab, peb yuav qhia txhua yam txog cov cim xeeb siv hauv SSDs, lawv qhov zoo thiab qhov tsis zoo, thiab qhov kev xaiv twg zoo dua thaum yuav qhov khoom lub xeev zoo. Nws kuj yuav pab tau: Kho SSD rau Windows 10, Yuav ua li cas hloov Windows 10 los ntawm HDD rau SSD, Yuav ua li cas thiaj paub qhov ceev ntawm SSD.
Hom cim xeeb flash siv hauv SSD rau kev siv hauv tsev
Lub SSD siv kev nco tau, uas yog qhov tshwj xeeb tshaj tawm lub cim xeeb ntawm tes raws li cov khoom sib tshooj, uas yuav txawv nyob hauv hom.
Hauv cov ntsiab lus dav dav, flash nco siv hauv SSDs tuaj yeem muab faib ua hom qab no.
- Los ntawm cov ntsiab lus ntawm kev nyeem ntawv-sau yuav luag txhua tus neeg siv khoom lag luam SSDs yog ntawm NAND hom.
- Raws li cov ntaub ntawv siv thev naus laus zis, lub cim xeeb tau muab faib ua SLC (Tib-theem ntawm tes) thiab MLC (Multi-level Cell). Hauv thawj kis, lub xov tooj ntawm tes tuaj yeem khaws cia me ntsis ntawm cov ntaub ntawv, hauv ob - ntau dua me ntsis. Tib lub sijhawm, hauv SSD rau kev siv hauv tsev koj yuav tsis pom SLC qhov nco, tsuas yog MLC.
Nyeg, TLC kuj tseem yog hom MLC, qhov txawv yog tias hloov 2 kab lus cov ntaub ntawv nws tuaj yeem khaws 3 me me ntawm cov ntaub ntawv hauv qhov chaw nco (hloov ntawm TLC koj tuaj yeem pom lub npe 3-ntsis MLC lossis MLC-3). Ntawd yog, TLC yog subspecies ntawm MLC lub cim xeeb.
Qhov twg yog qhov zoo dua - MLC lossis TLC
Feem ntau, MLC lub cim xeeb muaj qhov zoo dua TLC, lub hauv paus yog:
- Muaj kev kub ceev dua.
- Kev pab lub neej ntev dua.
- Kev siv hluav taws xob tsawg.
Qhov tsis zoo yog tus nqi siab ntawm MLC piv rau TLC.
Txawm li cas los xij, nws yuav tsum tau yug hauv siab tias peb tab tom tham txog "cov xwm txheej dav dav", hauv cov khoom siv tiag tiag ntawm kev muag koj tuaj yeem pom:
- Kev ua haujlwm ceev sib npaug (lwm yam tau sib npaug) rau SSDs nrog TLC thiab MLC nco txuas nrog ntawm SATA-3 interface. Ntxiv mus, tus kheej TLC-tawm tsav nrog PCI-E NVMe tuaj yeem qee zaum nrawm dua li cov ntsuas zoo sib xws nrog PCI-E MLC (txawm li cas los xij, yog tias peb tham txog "saum toj kawg", feem ntau kim thiab ceev tshaj SSDs, lawv tseem MLC lub cim xeeb feem ntau yog siv, tab sis kuj tsis tas li).
- Lub Sijhawm Siv Zog Siv Sijhawm ntev (TBW) rau TLC lub cim xeeb los ntawm ib lub chaw tsim khoom (lossis ib kab tsav) piv rau MLC nco los ntawm lwm cov chaw tsim khoom (lossis lwm SSD kab).
- Zoo ib yam li kev siv fais fab - piv txwv li, SATA-3 tsav nrog TLC lub cim xeeb tuaj yeem haus kaum lub zog tsawg dua PCI-E tsav nrog MLC lub cim xeeb. Ntxiv mus, rau ib hom kev nco thiab ib qho kev sib txuas sib txuas, qhov sib txawv ntawm lub zog noj kuj sib txawv raws li cov tsav tshwj xeeb.
Thiab cov no tsis yog txhua yam: qhov ceev, kev pab lub neej thiab kev siv fais fab yuav tseem sib txawv ntawm "tiam" ntawm tsav (tshiab dua, raws li txoj cai, zoo dua qub: tam sim no SSD tau txuas ntxiv txhim kho thiab txhim kho), nws tag nrho cov ntim thiab qhov ntau ntawm qhov chaw pub dawb thaum siv thiab txawm tias qhov kub thiab txias thaum siv (rau ceev NVMe drives).
Raws li qhov txiaj ntsig, qhov kev txiav txim siab nruj thiab qhov tseeb tias MLC zoo dua TLC tsis muaj peev xwm muab piv txwv - piv txwv li, los ntawm kev yuav khoom ntau dua thiab muaj SSD tshiab nrog TLC thiab cov teeb tsa zoo dua ntawm cov yam ntxwv, koj tuaj yeem yeej txhua qhov sib piv piv rau kev yuav tsav nrog MLC ntawm tus nqi, t .e. tag nrho cov kev ntsuas yuav tsum tau coj mus rau hauv tus account, thiab qhov kev tsom xam yuav tsum tau pib nrog kev siv peev txheej pheej yig (piv txwv li, hais txog kev siv nyiaj txog li 10,000 rubles, feem ntau yog tsav nrog TLC nco yuav zoo dua rau MLC rau ob qho tib si SATA thiab PCI-E).
SSDs nrog QLC cim xeeb
Txij li thaum kawg ntawm xyoo tas los, cov khoom siv khov kho nrog kev ua haujlwm nrog QLC nco (plaub-theem ntawm tes, i.e. 4 kab ntawm ib lub cim xeeb ntawm tes) tau tshwm sim rau ntawm kev muag khoom, thiab, tej zaum, xyoo 2019 yuav muaj ntau dua li cov tsav, thiab lawv cov nqi cog lus yuav txaus nyiam.
Cov khoom kawg yog pom los ntawm cov txiaj ntsig zoo hauv qab no thiab cov lus piv piv rau MLC / TLC:
- Tus nqi qis dua hauv qab gigabyte
- Kev nco tau zoo dua yuav hnav thiab, raws li kev xav, yuav muaj peev xwm dua ntawm cov ntaub ntawv sau cia yuam kev
- Cov ntaub ntawv sau nrawm dua
Nws tseem nyuaj los tham txog cov lej tshwj xeeb, tab sis qee qhov piv txwv ntawm cov uas twb muaj muag tau tuaj yeem kawm: piv txwv, yog koj coj tus nqi zoo ib yam li 512 GB M.2 SSD tsav los ntawm Intel raws QLC 3D NAND thiab TLC 3D NAND nco, kawm cov kws tsim khoom tshwj xeeb. saib:
- 6-7 txhiab rubles tawm tsam 10-11 txhiab rubles. Thiab rau tus nqi ntawm 512 GB TLC, koj tuaj yeem xaj 1024 GB QLC.
- Cov ntawv tshaj tawm ntawm cov ntaub ntawv kaw tseg (TBW) yog 100 TB rau 288 TB.
- Kev khiav ceev ntawm kev sau ntawv / nyeem ntawv yog 1000/1500 tiv thaiv 1625/3230 Mb / s.
Ntawm qhov one hand, cons tuaj yeem tshaj qhov zoo ntawm tus nqi. Ntawm qhov tod tes, koj tuaj yeem nqa mus rau hauv tus account lub sijhawm no: rau SATA disks (yog tias koj tsuas muaj xws li interface muaj) koj yuav tsis pom qhov sib txawv hauv qhov ceev thiab qhov nce ceev yuav tseem ceeb heev piv rau HDD, thiab TBW parameter rau QLC SSD yog 1024 GB (uas hauv kuv Ib qho piv txwv raug nqi ib yam li 512 GB TLC SSD) twb tau 200 TB (qhov khoom loj-lub zog yuav "nyob ntev dua", vim yog txoj kev raug kaw cia rau lawv).
V-NAND nco, 3D NAND, 3D TLC, thiab lwm yam.
Hauv cov lus piav qhia ntawm SSD lub zog (tshwj xeeb tshaj yog thaum nws los txog Samsung thiab Intel) hauv khw muag khoom thiab kev tshuaj xyuas koj tuaj yeem nrhiav cov qauv tsim V-NAND, 3D-NAND thiab zoo sib xws rau cov cim xeeb.
Kev tsim qauv no qhia tau tias lub cim xeeb flash yog nyob rau ntawm cov nti hauv ntau txheej (hauv cov chips yooj yim, cov hlwb nyob hauv ib txheej, ntau dua ntawm Wikipedia), thaum lub sijhawm no zoo tib yam TLC lossis MLC nco, tab sis qhov no tsis tau hais meej meej txhua qhov chaw: piv txwv li, rau Samsung SSDs koj tsuas yuav pom tias V-NAND nco tau siv, txawm li cas los xij, cov ntaub ntawv uas EVO kab siv V-NAND TLC, thiab cov kab PRO tsis ib txwm qhia V-NAND MLC. Tsis tas li tam sim no QLC 3D NAND drives tau tshwm sim.
Puas yog 3D NAND zoo dua li planar nco? Nws yog qhov pheej yig dua rau kev tsim khoom thiab kuaj pom tias niaj hnub no rau TLC lub cim xeeb, qhov kev xaiv ntau txheej txheem feem ntau yog qhov ua tau zoo dua thiab muaj kev ntseeg siab (ntxiv, Samsung thov tias V-NAND TLC lub cim xeeb muaj qhov ua tau zoo dua thiab kev pab cuam lub neej dua planar MLC). Txawm li cas los xij, rau MLC lub cim xeeb, suav nrog hauv lub moj khaum ntawm cov twj ntawm tib lub chaw tsim khoom, qhov no yuav tsis yog. I.e. ib zaug ntxiv, nws txhua tus nyob ntawm cov cuab yeej tshwj xeeb, koj cov peev nyiaj thiab lwm yam kev ntsuas uas yuav tsum tau kawm ua ntej yuav muas SSD.
Kuv yuav zoo siab pom zoo rau Samsung 970 Pro tsawg kawg 1 TB yog qhov kev xaiv zoo rau lub tsev computer lossis laptop, tab sis feem ntau cov nqi qis dua yuav, rau qhov uas koj yuav tsum ua tib zoo kawm tag nrho cov qauv ntawm cov yam ntxwv thiab piv lawv nrog dab tsi raws nraim uas yuav tsum tau los ntawm kev tsav.
Li no qhov tsis muaj cov lus teb meej, thiab hom kev nco zoo dua. Ntawm chav kawm, muaj peev xwm tsim tau SSD nrog MLC 3D NAND hais txog qhov teeb tsa ntawm cov yam ntxwv yuav yeej, tab sis tsuas yog ntev npaum li cov yam ntxwv no tau txiav txim siab cais tawm ntawm tus nqi ntawm tus tsav. Yog tias peb coj cov lus hais no mus rau hauv tus account, Kuv tsis suav qhov ua tau tias QLC disks yuav zoo dua rau qee cov neeg siv, tab sis "nruab nrab hauv av" yog TLC nco. Thiab tsis muaj teeb meem twg SSD uas koj xaiv, Kuv pom zoo kom coj cov thaub qab ntawm cov ntaub ntawv tseem ceeb.
