SATA2.0 thiab SATA3.0 qhov pom ntawm kab saum toj no tsis pom qhov sib txawv loj, cov tuam txhab txawv ntawm cov kab sib txawv ntawm cov cable yuav nyob rau xim thiab cable saum lub logo saum cov kab hlau txuas mus txhawb SATA2.0 los sis SATA3.0, tab sis seb nws yog SATA2.0 cable siv nyob rau hauv SATA3.0 hard drive thiab motherboard, los yog SATA3.0 cable siv nyob rau hauv SATA2.0 nyuaj tsav thiab lub motherboard yuav tshwm sim ntawm, tsis muaj yuav muaj teeb meem compatibility ntawm lub specifications.
Txawm li cas los xij, yog qhov nyuaj disk thiab motherboards SATA3.0 cov khoom siv txhawb zog, tab sis nrog lub SATA2.0 cable yog qhov kev nyuab siab tseem yuav yog SATA2.0 txuj ci, yog li yog siv lub motherboard SATA3.0 interface thiab SATA3.0 nyuab tsav, ces cov lus piav qhia siv cable SATA3.0 cable, kev txhawb SATA3.0 motherboard accessories yuav muaj SATA3.0 cable.
SATA2.0 thiab SATA3.0 qhov sib txawv yog tias cov qauv tshiab hloov cov qauv, tsis txawv interface specifications, ob lub interfaces yog sib luag, sib txawv ntawm cov zajlus kom txawv, rau kev ua tau zoo ntawm qhov kev hloov kho, los yog nyob ntawm lub hard disk nws tus kheej thiab lub niam ntawv Qhov kev txiav txim siab los txiav txim siab, qhov kev xav yuav txhim khu ntau, tab sis qhov tseeb daim ntawv thov yog feem ntau tsis muaj neeg kho tshuab hard disk thiab solid-state hard drive kom pom tseeb.
Qhov kev hloov ntawm theoretical SATA2.0 interface yog 150MB / s, thiab SATA3.0 interface npaum li cas: 300MB / s, lwm qhov kev ntsuas ntawm qhov nyuaj disk tsis muaj thiab cache peev. Feem ntau muaj 8MB, 16MB, 32MB thiab 64MB ntsiab lus. Tab sis theoretically cim qhov nruab nrab ntawm qhov kev siv ntawm qhov tseeb uas tsis muaj kev xav meej.
SATA2.0 hard drive siab tshaj plaws nyeem kom txog li 125.0MB / s, siab tshaj plaws sau ntawm 99.1MB / s. SATA3.0 hard disk nruab nrab nyeem thiab sau ntawv ceev ntawm 118MB / S thiab 99.4MB / S. Los ntawm kev sim peb pom tau SATA2.0 hard drive thiab SATA3.0 hard drive, nyeem thiab sau qhov sib txawv ceev tsis yog pom tseeb, tsuas yog lub sijhawm ceev SATA3.0 hard drive ua ntej ntau dua nyob rau hauv cov ntaub ntawv tseeb SATA3.0 Ntau tshaj.
