SATA II yog tsim los ntawm nti loj Intel Intel thiab hard disk loj heev Seagate. Nws lub ntsiab feature yog tias tus nqi sab nraud lwm tus tau ntxiv ntxiv ntawm SATA 150MB / s mus rau 300MB / s. Sata3 yog ib tug tshiab version ntawm Serial ATA International (SATA-IO) tso tawm hauv lub Tsib Hlis 2009, tsuas yog mus rau ob qho kev sib txuas ceev kom txog 6Gbps, thaum rov mus tshaj qhov qub version of "SATA Revision2.6" (tseem hu ua SATA 3Gbps). Lub interface thiab cov kab ntawv tsis hloov. Tus qauv SATA3.0 interface tau tsim los ntawm Intel Corporation hauv thawj ib nrab ntawm 2007. Nws tau daws los ntawm Knut Grimsrud, Tus Thawj Coj ntawm Kev Khoom Khoom Siv Architecture Architecture Department ntawm Intel Corporation. Knut Grimsrud tau hais tias kev xa tus nqi ntawm SATA3.0 yuav ncav cuag 6Gbps thiab yuav muab doubled raws li SATA2.0 kis tau tus nqi.
Ceev sib piv ntawm Sata2 thiab sata3
Lub ntsiab sib txawv ntawm SATA2 thiab SATA3 yog sib txawv kis tus nqi. Qhov tseeb SATA3 kis tau tus nqi tuaj yeem ncav txog 6 Gb / s, thaum lub SATA2 interface muaj kev sib kis ntawm 3Gb / s. Ntawm tus nqi kis, tus SATA2 hard disk interface tau ua tsis tau raws li cov kev xav tau ntawm SSDs thiab ib co Qualcomm neeg kho tshuab hard disks.
Nws yuav tsum raug sau tseg tias qhov kev nyeem ntawv zoo tshaj plaws rau lub hard disk tsis yog nyob ntawm qhov nyuaj disk nkaus xwb, tiam sis tseem nyob rau qhov nyuaj disk interface. Nyob rau hauv lwm yam lus, ntev npaum li lub hard disk txhawb STA3.0 interface, thiab lub hard disk ntawm no lub computer txuas nrog lub motherboard txhawb SATA3.0 interface yuav ua zoo tshaj plaws kev ua tau zoo, yog li qee cov laus hauv computer nyuaj drives, qhov nyiaj pab ntau tshaj tsuas SATA2.0, thaum no hom hard disk txuas nrog lub SATA3.0 motherboard, qhov kev ceev tseem yog tus ceev ntawm SATA2, vim tias qhov hard disk nws tus kheej raug mob.
Sib piv sib piv ntawm sata2 thiab sata3
Los ntawm cov tsos, SATA3 thiab SATA2 interfaces ntawm lub motherboard yeej zoo li qub, tab sis nyob rau ntau motherboards, thiaj li qhia rau cov neeg siv qhov sib txawv sata2 thiab sata3 hard disk interfaces, txawv xim feem ntau cim. Feem coob ntawm cov niam txiv uas txhawb STA3.0 interface sata2 yog dub, thaum SATA3 interfaces yog daj / dawb / xiav, raws li qhia hauv daim duab nram qab no:
SATA2 thiab SATA3 motherboard hard disk interface tsos yeej zoo li qub, tab sis ntau cov niam txiv uas tsis tshua muaj siab tseem siv sata2 thiab sata3 dual interface hybrid hom, xws li AMD platform A75, Intel platform B75, H81, B85 motherboard yog sata2 thiab sata3 dual interface hybrid hom , thiab qee qhov kev xeem ntawm ib nrab-rau-high-end, xws li A88, H87, Z87 thiab lwm tus motherboards yog tag nrho SATA3.0 interfaces.
Hauv qab txheej sib piv ntawm sata2 thiab sata3
HD Tune yog ib qho kev ua haujlwm nyuaj tsav ntsuas kev ntsuas. Nws tuaj yeem txhim kho tus nqi qiv paj, tawg paj ntaub, nqi ntaub ntawv, CPU kev siv, kev noj qab haus huv, kub thiab scan disk nto. Ntxiv mus, qhov firmware version, naj npawb tooj, muaj peev xwm, cache qhov me me, thiab hloov tam sim no hom hard disk yuav pom nyob rau hauv kev nthuav dav.
Hauv HD qhib hauv SSD, peb tsuas yog xa mus rau qhov nruab nrab nyeem ntawv ceev ntawm qhov kev xeem. Tus neeg SATA3 interface, choj SATA3.0 interface thiab SATA2.0 interface muaj qhov nruab nrab nyeem ntawv ceev ntawm 359.8MB / s, 241.6MB / s thiab 204.3MB / s.
SSD kev txuag txhua qhov kev sib piv Sib piv ntawm SATA2 thiab SATA3
Ua tus PCMark7 khiav xeem thiab xaiv PCMark7 tus pabcuam cia tus qhab-nees ua tus qhauj khoom. Qhov thib ob cia cov qhab nees qis tshaj plaws rau kev sim ntsuas kev tsav tsheb ntawm lub computer ntawm disk.
Hauv PCMark khiav, Flash Flash Extreme Speed Series 240GB SSD yog siv los ua ib tug qhev ntawm Intel i7-3770k ntxiv rau ASUS M5F motherboard platform, 5376 nyob rau hauv cov haiv neeg SATA3.0 interface thiab 5161 hauv qab SATA3.0 interface. Tsuas 4531 hauv SATA2.0 interface. Qhov txawv yog ntau tshaj 700 ntsiab lus. Qhov no yog qhov kev sib txawv ntawm qhov cia tag nrho thiab khiav.
