Yuav ua li cas kom paub qhov txawv ntawm SATA 2 thiab SATA 3?
Nkag Siab Txog Qhov Tseem Ceeb Ntawm Cov Qauv Sib Txawv
Thaum koj tab tom sib sau ua ke lub computer, hloov kho lub hard drive, lossis daws teeb meem kev ua haujlwm, nws yog ib qho tseem ceeb heev uas yuav tsum paub qhov txawv ntawm SATA 2 (SATA II) thiab SATA 3 (SATA III) interfaces kom raug. Txawm hais tias ob tiam neeg ntawm cov interfaces no zoo sib xws, lawv qhov sib txawv ntawm kev ua haujlwm yog qhov tseem ceeb. Tsab xov xwm no yuav muab ntau txoj hauv kev siv tau los pab koj yooj yim paub qhov txawv ntawm lawv, thiab tseem hais txog qee cov qauv interface siab, xws liSAS SFF-8654 4I 38Pthiab lwm yam kev qhia tshwj xeeb.
I. Kev Txheeb Xyuas Sai Sai ntawm Txoj Kev Xav: Qhov Sib Txawv Tseem Ceeb Ntawm SATA 2 thiab SATA 3
Ua ntej ua qhov sib txawv, cia peb nkag siab txog cov kev cai yooj yim:
SATA 2: Qhov ceev tshaj plaws theoretical yog 3 Gbps (kwv yees li 300 MB / s), qhia tawm xyoo 2004.
SATA 3: Qhov ceev tshaj plaws theoretical yog 6 Gbps (kwv yees li 600 MB / s), qhia tawm xyoo 2008.
Ob lub interfaces muaj tib lub cev zoo li cas, tab sis lawv sib xws (SATA 3 li siv tau rau SATA 2 interfaces, tab sis qhov ceev yog txwv).
Nws yog ib qho tsim nyog sau tseg tias nyob rau hauv kev tshaj lij thiab kev lag luam-theem cia khoom, cov qauv interface muaj ntau yam sib txawv. Piv txwv li,SAS SFF-8654 4I 38Pyog ib qho interface specification siv rau hauv cov high-performance storage systems, muab bandwidth thiab kev ntseeg siab dua li SATA ib txwm muaj. Tsis tas li ntawd,SFF 8654 4I rau U.2cov adapters tso cai rau U.2 NVMe solid-state drives txuas rau cov kab ke uas txhawb nqaSAS SFF-8654 4I 38Pinterface, uas yog ib txwm muaj nyob rau hauv cov kev daws teeb meem cia khoom lag luam. Lub caij no, cov tsoos4X SFF 8482interface kuj yog ib qho qauv SAS interface siv los txuas ntau lub hard drives.
II. Tsib Txoj Kev Sib Txawv Uas Siv Tau Zoo
1. Xyuas cov ntawv lo rau ntawm lub motherboard lossis hard drive
Cov motherboard SATA interfaces: Feem ntau cov motherboard muaj cov ntawv lo ze ntawm cov interfaces. Cov ntawv lo feem ntau suav nrog:
SATA 3: Tej zaum yuav raug cim ua "SATA 6G", "SATA 6Gb/s", lossis "SATA III".
SATA 2: Tej zaum yuav raug cim ua "SATA 3G", "SATA 3Gb/s", lossis "SATA II".
Cov ntawv lo rau ntawm lub hard drive: Cov SATA solid-state drives lossis cov mechanical hard drives feem ntau muaj cov interface version sau rau ntawm lawv cov ntawv lo.
Thaum ua haujlwm nrog cov khoom siv cia khoom lag luam, koj yuav ntsib cov kev sib txuas lus zoo liSAS SFF-8654 4I 38PCov interfaces no feem ntau yog siv rau hauv cov txheej txheem cia khoom siv siab thiab muaj kev ceev ntau dua li cov interfaces SATA ib txwm muaj. Yog tias koj xav tau txuas U.2 li rau cov kab ke zoo li no,SFF 8654 4I rau U.2cov adapters ua tau zoo heev. Lub caij no, cov SAS systems qub dua yuav siv tau4X SFF 8482cov interfaces los txuas rau hard drive backplanes.
2. Paub qhov txawv los ntawm Xim (Tsis yog Tus Qauv Tseeb)
Ntau lub tuam txhab tsim motherboard siv cov xim coding:
SATA 3 interfaces: Feem ntau yog xiav, dawb, lossis dub.
SATA 2 interfaces: Feem ntau yog xim dub, grey, lossis daj.
Txawm li cas los xij, xim tsis yog tus qauv thoob ntiaj teb (piv txwv li, ASUS feem ntau siv xiav rau SATA 3, thaum Gigabyte siv dawb). Nws raug pom zoo kom muab lwm txoj hauv kev los ua ke rau kev lees paub.
Nyob rau hauv sib piv, cov kev sib txuas lus zoo liSAS SFF-8654 4I 38Pfeem ntau muaj cov cim qhia meej dua.SFF 8654 4I rau U.2cov adapters kuj muaj cov yam ntxwv tshwj xeeb uas ua rau lawv yooj yim txheeb xyuas.4X SFF 8482interface, ntawm qhov tod tes, yog qhov txuas dav dua feem ntau siv rau SAS nthuav dav.
3. Saib phau ntawv qhia txog cov khoom siv kho vajtse
Phau ntawv qhia txog motherboard: Txoj kev ntseeg tau tshaj plaws. Ntu "Storage Interface" lossis "Specification" yuav teev meej meej cov version thiab qhov chaw ntawm txhua lub SATA interface.
Phau ntawv qhia txog lub hard drive: Nws yuav qhia txog SATA version uas txhawb nqa.
Rau cov khoom siv hauv theem lag luam, phau ntawv qhia yuav muab cov lus piav qhia ntxaws ntxaws txog cov lus qhia thiab kev siv ntawmSAS SFF-8654 4I 38Pinterface. Yog tias koj xav tau siv lubSFF 8654 4I rau U.2cov kev daws teeb meem adapter, phau ntawv qhia kuj tseem yuav muab cov lus qhia teeb tsa sib xws. Ib yam li ntawd, cov khoom siv txhawb nqa4X SFF 8482lub interface yuav raug cim kom meej meej hauv cov ntaub ntawv.
4. Siv software nrhiav
Cov cuab yeej xws li CrystalDiskInfo thiab HWiNFO: Tuaj yeem nrhiav tau SATA version uas lub hard drive txhawb nqa (qhia ua "Transfer Mode").
Lus Cim: Kev kuaj pom software qhia txog lub peev xwm ntawm lub hard drive, tsis yog qhov version ntawm lub motherboard interface. Yog tias lub hard drive txhawb nqa SATA 3 tab sis nws khiav hauv hom SATA 2, nws yuav qhia tau tias lub motherboard interface yog SATA 2.
Rau cov kev sib txuas lus zoo liSAS SFF-8654 4I 38P, tej zaum yuav xav tau cov software tswj hwm tshwj xeeb rau kev txheeb xyuas thiab teeb tsa. Qhov xwm txheej ntawmSFF 8654 4I rau U.2adapter kuj tseem tuaj yeem pom los ntawm cov cuab yeej no. Cov khoom siv txuas nrog rau4X SFF 8482feem ntau yuav tsum tau kuaj xyuas qhov interface hauv RAID card management interface.
5. Saib cov interface pins (txuj kev siab heev)
Lub SATA interface muaj 7 tus pin sab hauv, tab sis qhov version tsis tuaj yeem sib txawv ncaj qha los ntawm qhov tsos. Yog tias muaj xwm txheej tso cai, koj tuaj yeem xa mus rau cov lej silk-screen ntawm lub motherboard PCB (xws li SATA3_0, SATA2_3, thiab lwm yam).
Nyob rau hauv kev sib piv, lubSAS SFF-8654 4I 38Pinterface muaj 38 pins, uas yog ib feem ntawm nws lub npe. LubSFF 8654 4I rau U.2tus adapter yuav tsum txuas cov pins no kom raug.4X SFF 8482interface muaj ntau lub pins thiab txhawb nqa plaub-channel cov ntaub ntawv kis tau tus mob.
III. Kev txheeb xyuas kev ua tau zoo los ntawm kev sim tiag tiag
Yog tias koj twb tau txuas lub hard drive lawm, koj tuaj yeem txiav txim siab tsis ncaj qha los ntawm kev sim ceev:
Siv CrystalDiskMark los sim qhov ceev nyeem thiab sau tas mus li.
Yog tias qhov ceev tsis tu ncua qis dua 250-300 MB/s, nws yuav khiav hauv hom SATA 2 (txawm tias lub hard drive txhawb nqa SATA 3).
Yog tias qhov ceev tshaj 500 MB/s, nws yuav khiav hauv hom SATA 3.
Thaum siv lubSAS SFF-8654 4I 38Pinterface, kev ntsuam xyuas kev ua tau zoo yuav qhia tau qhov ceev dua vim nws txhawb nqa bandwidth siab dua. NVMe hard drives txuas los ntawmSFF 8654 4I rau U.2tus adapter tuaj yeem siv lawv lub peev xwm ua tau zoo tag nrho. Ib yam li ntawd,4X SFF 8482interface tuaj yeem muab cov bandwidth siab dua li ib-channel SATA.
IV. Cov Lus Cim
Kev cuam tshuam ntawm kev siv sib xyaw: Kev txuas lub hard drive SATA 3 rau lub interface SATA 2 yuav txwv kev ua haujlwm (downgrading mus rau SATA 2 theem), tab sis yuav tsis muaj teeb meem sib xws.
Lub laptop lossis lub tshuab hom: Qhov chaw sab hauv me me. Nws raug pom zoo kom xa mus rau cov ntaub ntawv qhia tshwj xeeb lossis cov lus qhia txog kev rhuav tshem.
Cov cables SATA: Cov cables SATA 3 muaj kev ua tau zoo dua los tiv thaiv, tab sis kev sib xyaw ua ke feem ntau tsis cuam tshuam rau kev lees paub (tej zaum yuav cuam tshuam rau kev ruaj khov hauv cov chaw ceev ceev).
Hauv ib puag ncig ua lag luam, teeb tsa kom raugSAS SFF-8654 4I 38Pinterface tseem ceeb heev. Thaum siv lubSFF 8654 4I rau U.2adapter, nws yog qhov tsim nyog los xyuas kom meej tias firmware thiab tsav tsheb sib xws. Rau qhov4X SFF 8482interface, kev tswj hwm cable kom zoo yog qhov tseem ceeb rau kev ncaj ncees ntawm lub teeb liab.
V. Cov Lus Qhia Luv Luv thiab Cov Lus Qhia
Muab qhov tseem ceeb rau kev kuaj xyuas cov ntawv lo thiab cov lus qhia - qhov ncaj qha tshaj plaws thiab txhim khu kev qha.
Ua ke xim thiab software nrhiav - cross-validation.
Yog tias tsim nyog, ua qhov kev sim ceev - paub meej tias hom kev ua haujlwm tiag tiag.
Kev paub qhov txawv ntawm cov qauv SATA kom raug yuav pab tau koj kom phim cov khoom siv kho vajtse kom raug thiab siv tau tag nrho cov kev ua haujlwm ntawm cov khoom siv khaws cia. Thaum hloov kho dua tshiab, nws raug pom zoo kom txuas cov tsav tsheb ceev ceev (xws li SSDs) rau SATA 3 interface, thiab cov tsav tsheb nyuaj mechanical tuaj yeem txuas rau SATA 2 interface kom txuag tau cov peev txheej interface ceev ceev.
Rau cov neeg siv kev tshaj lij uas xav tau kev ua tau zoo dua, nkag siab txog cov qauv interface zoo liSAS SFF-8654 4I 38Pmuaj nqis heev.SFF 8654 4I rau U.2kev daws teeb meem muab cov kev xaiv sib txuas yooj ywm rau NVMe cia. Lub caij no, txawm hais tias4X SFF 8482yog tus qauv qub dua, nws tseem ceeb heev rau ntau lub tshuab uas twb muaj lawm. Txawm siv lub interface twg los xij, kev txheeb xyuas thiab kev teeb tsa kom raug yog qhov tseem ceeb rau kev ua haujlwm zoo tshaj plaws.
