USB thiab FireWire tau txais txiaj ntsig zoo rau kev cia sab nraud. Txawm li cas los xij, kev ua haujlwm ntawm cov khoom siv khaws cia no piv rau desktop drives ib txwm lagged. Nrog rau txoj kev loj hlob ntawm Serial ATA (SATA) cov qauv, ib tug tshiab sab nraud cia hom, sab nraud Serial ATA, tau nkag mus rau hauv lub lag luam.
Sab Nraud SATA yog tus qauv kev lag luam rau kev tswj hwm ntau yam khoom siv siv los txuas cov khoom siv sab nraud. Nws sib tw nrog qee tus qauv Firewire thiab USB los muab cov ntaub ntawv hloov pauv sai ntawm cov khoom siv kho vajtse.
Yuav ua li cas eSATA piv nrog USB thiab FireWire?
Ob qho tib si USB thiab FireWire interfaces yog kev sib txuas ceev ceev ntawm lub khoos phis tawj thiab cov khoom siv sab nraud. USB yog dav dav thiab siv rau ntau yam khoom siv xws li cov keyboards, nas, scanners, thiab tshuab luam ntawv. FireWire yuav luag tsuas yog siv los ua qhov chaw cia sab nraud.
Txawm hais tias cov kev sib tshuam no tau siv rau kev cia sab nraud, cov tsav siv hauv cov khoom siv no siv SATA interface. Cov ntaub thaiv sab nraud uas nyob hauv lub hard drive lossis optical drive siv tus choj uas hloov cov teeb liab ntawm USB lossis FireWire interface rau hauv SATA interface xav tau los ntawm tus tsav. Qhov kev txhais lus no ua rau qee qhov kev puas tsuaj hauv kev ua haujlwm tag nrho ntawm tus tsav.
Ib qho txiaj ntsig uas ob qho tib si ntawm cov kev sib tshuam no tau siv yog qhov kub-swappable peev xwm. Cov tiam dhau los ntawm kev sib txuas cia feem ntau tsis txhawb nqa lub peev xwm kom muaj cov tsav dynamically ntxiv lossis tshem tawm ntawm lub kaw lus. Qhov no yog qhov ua rau kev lag luam cia sab nraud tawg.
Lwm qhov nthuav dav uas tuaj yeem pom nrog eSATA yog qhov chaw nres nkoj sib npaug. Qhov no tso cai rau ib leeg eSATA connector siv los txuas rau sab nraud eSATA chassis uas muab ntau lub drives hauv ib qho array. Qhov no tuaj yeem muab kev nthuav dav ntxiv rau hauv ib lub chassis thiab lub peev xwm los tsim cov khoom siv rov ua dua ntawm RAID array.
eSATA vs. SATA
Sab Nraud Serial ATA yog ib qho ntawm cov ntsiab lus ntxiv rau Serial ATA interface tus qauv. Nws tsis yog qhov yuav tsum tau ua, tab sis qhov txuas ntxiv uas tuaj yeem ntxiv rau ob qho tib si maub los thiab cov khoom siv. Rau eSATA kom ua haujlwm zoo, ob qho tib si txuas nrog yuav tsum txhawb nqa qhov tsim nyog SATA nta. Ntau lub cim SATA thaum ntxov thiab cov tsav tsheb tsis txhawb nqa lub Plug Kub uas yog qhov tseem ceeb rau kev ua haujlwm ntawm sab nraud interface.
Txawm hais tias eSATA yog ib feem ntawm SATA interface specifications, nws siv lub cev sib txawv ntawm cov khoom sib txuas hauv SATA kom zoo dua tiv thaiv cov kab hluav taws xob nrawm hloov cov teeb liab tawm tsam EMI cuam tshuam. Nws kuj muab 2-meter tag nrho cable ntev piv rau 1 meter rau hauv cables. Raws li qhov tshwm sim, ob lub cables tsis hloov pauv tau.
Puas muaj qhov sib txawv nrawm ntawm eSATA thiab SATA?
Ib qho ntawm cov txiaj ntsig tseem ceeb uas eSATA muaj tshaj USB thiab FireWire yog qhov nrawm. Txawm hais tias ob qho tib si cuam tshuam nyiaj siv ua haujlwm los ntawm kev hloov lub teeb liab ntawm sab nraud interface thiab cov tsav sab hauv, SATA tsis muaj qhov teeb meem no. Vim hais tias SATA yog tus qauv interface siv rau ntau lub hard drives tshiab, ib qho yooj yim converter ntawm lub sab hauv thiab sab nraud connectors yuav tsum tau nyob rau hauv vaj tse. Yog li, cov cuab yeej sab nraud yuav tsum khiav ntawm tib lub nrawm li ib qho SATA tsav sab hauv.
Qhov sib txawv sib txawv txhua tus muaj qhov theoretical siab tshaj plaws hloov ceev:
- USB 1.1: 15 Mbps
- FireWire (1394a): 400 Mbps
- USB 2.0: 480 Mbps
- FireWire 800 (1394b): 800 Mbps
- SATA 1.5: 1.5 Gbps
- SATA 3.0: 3.0 Gbps
- USB 3.0: 4.8 Gbps
- USB 3.1: 10 Gbps
Cov qauv USB tshiab tau nrawm dua hauv kev xav dua li SATA interface uas cov tsav tsheb hauv cov ntaub thaiv sab nraud siv. Vim hais tias ntawm cov nyiaj siv ua haujlwm ntawm kev hloov cov teeb liab, lub USB tshiab tseem ua pov thawj qeeb me ntsis. Txawm li cas los xij, rau cov neeg siv khoom feem ntau, yuav luag tsis muaj qhov sib txawv. Raws li, eSATA connectors yog tsis tshua muaj tam sim no, muab hais tias USB-raws li enclosures yog yooj yim dua.
FAQ
eSATA chaw nres nkoj siv rau dab tsi?
Ib qho chaw eSATA txuas rau cov tsav sab nraud xws li hard disk drives (HDDs) lossis kho qhov muag tsav nrog eSATA cable. Yog tias koj lub khoos phis tawj tsis muaj qhov chaw nres nkoj eSATA, koj tuaj yeem yuav lub adapter bracket.
Dab tsi yog eSATA / USB combo chaw nres nkoj?
Hom chaw nres nkoj no yog ib qho sib xyaw ntawm eSATA thiab USB, uas txhais tau tias nws tuaj yeem siv tau ob qho tib si USB thiab eSATA drives thiab connectors.
