ESATA thiab USB3.0 cov qauv txheej txheem thiab sib txawv

Lub hauv paus ntawm kev paub txog ib yam dab tsi yog qhov perceive nws. Ua ntej tshaj plaws peb tau paub eSATA thiab USB3.0 interface, ntsig txog, hom dab tsi. USB3.0 tsos thiab USB2.0 thiab tsis muaj qhov sib txawv, thiab kom paub qhov txawv nruab nrab ntawm cov ob qhov sib txawv ntawm qhov sib txawv, qhov kev lag luam muab USB3.0 interface xim yuav tsum xiav. Ntxiv mus, USB2.0 tsuas muaj plaub ntiv tes, thiab USB3.0 muaj cuaj.

Cov duab no yog heev intuitive qhia peb tias tus liab yog eSATA interface, thaum lub xiav yog USB3.0 interface

Li cas eSATA interface zoo li cas? Raws li pom saum toj no, hauv HDMI thiab USB3.0 interface nruab nrab ntawm lub qhov interface liab yog eSATA interface (eSATA interface, txhua yam xim, thiab tsis muaj qhov yuav tsum tau ua).

Mobile hard disk nrog 2.5-nti txhua yam tsav nyuab drive, tus ceev txwv tsawg dua eSATA (SATA2) txheem
Kis tau sai, USB3.0 muaj 5Gbps siab bandwidth, hloov dua siab tshiab rau qhov nqi ntawm txoj kev xav yog 500MB / S. ESATA nrog SATAII, nrog 3Gbps kis ceev, tom qab lub theoretical kis tau tus mob ntawm 300MB / S. Seemingly USB3.0 piv rau eSATA interface muaj kev yooj yim kiag li, tab sis kev rau hauv tus account qhov tseeb qhov teeb meem tsis yog qhov teeb meem. Vim hais tias nyob rau hauv lub hnub peb feem ntau ntawm kev siv ntawm 2.5-ntu mechanical hard drive raws li ib tug mobile hard disk (nrog loj-capacity SSD raws li ib tug mobile hard disk burner yog tsis nyob rau hauv lub Scope ntawm kev sab laj), thiab tam sim no txawm tus ceev tshaj 3.5- inch mechanical hard drive, kev sib kis ceev tsis tseem ceeb tshaj plaws yog 200MB / S. Txij thaum lub siab ceev tshaj plaws kuj yog eSATA (SATA2) 300MB / S hauv qab, qhov kev sib piv muaj ib lub ntsiab lus.

● ESATA thiab USB3.0 interface xa qhov kev sib ntaus los ntawm kev sib ntaus

Qhov kev sim no peb siv ob lub software, feem ntau, CrystalDiskMark thiab HD Tune. Nyob rau hauv CrystalDiskMark, qhov nyuaj disk nyeem thiab sau ntawv ceev yuav yog kev ua kom pom tseeb. Nyob rau hauv lub HD Tune, peb tsom mus rau kev soj ntsuam ib tug me me ntawm daim simulation ntaub ntawv ntawm ntsuas

ESATA KUAJ

USB3.0 cable

CrystalDiskMark los ntawm cov qhab-nees xeem, peb tuaj yeem pom, eSATA nyeem thiab sau ntawv qis qis dua USB3.0, tab sis qhov sib txawv yog qhov tsawg, yuav raug suav tias yog tib theem.

ESATA

USB3.0

Nyob rau hauv lub HD Tune kuaj cov ntaub ntawv benchmark, eSATA tseem piv nrog USB3.0. Peb 2000MB ntev ntawm cov ntaub ntawv raws li ib yam khoom ua ke, USB3.0 interface nyob rau hauv kev nyeem ceev ntu ntawm eSATA interface me ntsis ntxiv. Hauv 4KB tib random thiab ntau yam random, eSATA interface IOPS tus nqi tuav tswj USB3.0 interface thawj coj.

● xaus: muaj lawv tus kheej zoo, USB3.0 loj sib
Hauv qhov kev xeem no, peb tsis yog nyob rau hauv eSATA thiab USB3.0 no ob lub interfaces muaj ib qhov kev nkag siab zoo heev ntawm kev ua tau zoo ntawm nws? Hauv qhov tseeb ntawm kev xeem, ob qhov sib piv, nws tsis yog hais tias ob lub interfaces zoo li lub tswv yim, thiab thaum twg peb yuav khoom, tsuav yog xaiv cov cuab yeej nrog ib qho ntawm qhov interface tau nws?
Yeej tsis tseem. Hauv kev xaiv ntawm qhov interface, peb yuav tsum xav txog ntau yam. Ua ntej, lub eSATA cable tsuas muaj cov nyhuv ntawm cov ntaub ntawv xa mus, nws tsis tuaj yeem muaj hwj chim tau ntaus ntawv. Ua lwm yam lus, yog tias peb xav siv eSATA mobile devices, ntxiv rau eSATA cable mus txuas, tab sis kuj txuas mus rau lub zog qaum. Ob txoj kab nyob hauv ntau txoj kev siv cov mobile cumbersome, thiab USB3.0 kiag li tsis muaj qhov teeb meem no. Thiab USB3.0 USB2.0 tsuas yog muab 0.5A fais fab mov los ntawm kev nce ntawm 0.5A, rau hauv 1A tam sim no, lub hwj huam mov muaj peev xwm ntau zog.

Nyob rau hauv cov neeg kho tshuab hard disk ceev bottlenecks tsis tau tawg ua ntej, eSATA thiab USB3.0 interface tib lub sij hawm tus ceev ntawm sib piv. Tab sis los ntawm ntau yam thiab tom ntej tiam sis, USB3.0 interface yuav ntau dua thiab muaj zog, thiab eSATA interface yuav ua keeb kwm. Muaj plaub lub hauv paus: Thawj, eSATA xav tau ib lub hwj chim tshwj xeeb sab nraud, USB3.0 tsis tas yuav tsum tau. Thib ob, US3.0 choj nti tuaj yeem yuav nce siab tshaj plaws, ntau li ntau tau los txo qhov kev sib kis ceev. Qhov thib peb, USB3.0 USB2.0 tuaj yeem daws tsis tau tib lub sij hawm daim ntawv thiab nyeem cov kev txwv, qhov kev ua tau zoo ntawm duplex cov ntaub ntawv xa tawm. Thaum kawg, USB3.0 txog li 5Gbps bandwidth piv rau eSATA 3Gbps muaj qhov zoo dua kom meej, thiab yav tom ntej ntawm kev siv tshuab nyuaj, peb zoo li yuav tsum tau pom tau tias cov neeg tsav tsheb khiav ceev eSATA (SATA2) txwv.
