Kev Txawj Ntse Sab Nraud PC Tshem tawm ntawm SATA Cov Qauv
USB thiab FireWire tau ob qho tib si tau lub pob loj loj rau lwm qhov chaw cia, tab sis lawv qhov kev ua tau piv rau cov duab drives yeej ib txwm lagged behind. Nrog rau kev txhim kho ntawm cov tshiab Serial ATA cov qauv, ib hom tshiab txheej txheem cia, sab nraud Serial ATA, tam sim no pib nkag mus rau kev lag luam. Cov tshooj no yuav saib rau hauv tus tshiab interface, li cas nws sib piv rau cov qauv uas twb muaj lawm thiab seb nws txhais tau li cas ntawm lwm qhov chaw cia.
USB thiab FireWire
Ua ntej saib sab nraud Serial ATA los yog eSATA interface, nws tseem ceeb heev uas yuav tau saib cov USB thiab FireWire interfaces. Ob leeg ntawm cov interfaces no yog tsim los ua cov cuab yeej high-speed interfaces ntawm lub tshuab computer thiab sab nraud ntawm cov khoom hluav taws xob. USB ntau dua thiab siv rau ntau yam ntawm cov khoom ib ncig xws li twj keyboards, nas, scanners thiab tshuab luam ntawv thaum FireWire yuav luag tsuas siv los ua ib qho chaw cia sab nraud.
Txawm tias cov interfaces yog siv rau lwm cov cia, lub ntsiab drives siv nyob rau hauv cov khoom siv no tseem siv SATA interface . Qhov no txhais tau tias yog sab nraud enclosure uas tau los tsev lub zog los yog kho qhov muag muaj lub choj uas hloov cov teeb liab los ntawm USB los yog FireWire interface mus rau hauv SATA interface siv los ntawm tus tsav. Qhov txhais lus no ua rau qee qhov degradation nyob rau hauv tag nrho kev ua tau zoo ntawm tus tsav.
Ib qho ntawm cov txiaj ntsig loj uas ob qho tib si ntawm cov kev cuam tshuam kev siv tau yog qhov kub kub muaj peev xwm. Cov tiam dhau los ntawm kev txawb interfaces feem ntau tsis txhawb qhov kev muaj peev xwm muaj tsav tsheb ntxiv los yog tshem tawm ntawm lub system. Qhov no feature ib leeg yog li cas ua rau sab nrauv cia lag luam tawg.
Lwm nthuav feature uas tuaj yeem nrhiav tau nrog eSATA yog qhov chaw nres nkoj phaj. Qhov no tso cai rau tib lub eSATA connector siv coj los txuas rau sab nraud eSATA chassis uas muab ntau yam tsav hauv ib qho array. Qhov no yuav ua kom muaj kev cia siab ntxiv nyob rau hauv ib lub chassis thiab muaj peev xwm los tsim cov khoom tso rov tuaj ntawm RAID array .
eSATA vs. SATA
Sab nraud Serial ATA ua tau yog ib qho ntawm cov lus qhia ntxiv rau Serial ATA interface txheem. Nws tsis yog ib qho yuav tsum tau ua, tab sis kev txuas ntxiv uas yuav muab ntxiv rau ob qho tib si thiab cov khoom siv. Hauv kev yuam kom eSATA rau kev ua haujlwm ob qho tib si yuav tsum txhawb cov kev tsim nyog ntawm SATA. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj plaws thaum ntxov SATA controllers thiab drives tsis txhawb lub Kub Plug peev xwm uas tseem ceeb heev rau kev ua haujlwm ntawm sab nraud interface.
Txawm tias eSATA yog ib feem ntawm SATA interface specifications, nws siv qhov sib txawv ntawm lub cev los ntawm lub SATA connectors. Yog vim li cas qhov no yog kom zoo dua cov ntaub thaiv npog cov twj siv high-speed uas siv los hloov cov teeb meem ntawm kev tiv thaiv EMI. Nws tseem muab ib txoj kab 2m thoob plaws kabmob txuas nrog piv rau 1m rau sab hauv cables. Yog li ntawd, ob hom kab ke cable tsis tuaj yeem siv sib txuas.
Txawv Txawv
Ib qho tseem ceeb zoo uas eSATA muaj tshaj USB thiab FireWire yog qhov ceev. Thaum lub ob leeg muaj nyiaj siv ua haujlwm ntawm kev hloov lub teeb liab ntawm sab nraud interface thiab sab hauv lub ntsiab, SATA tsis muaj qhov teeb meem no. Vim hais tias SATA yog tus qauv siv rau ntau yam tshiab drives, ib qho yooj yim converter ntawm sab hauv thiab sab nraud connectors yuav tsum tau nyob hauv vaj tse. Qhov no txhais tau hais tias lub cuab yeej lwm tus yuav tsum khiav ntawm kev ceev ib yam li ib qho hauv SATA tsav.
Yog li, ntawm no yog cov speeds rau ntau yam interfaces:
- 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 - 10Gbps
Nws yuav tsum raug sau tseg tias cov kev qhia tshiab dua tshiab ntawm USB tshiab tam sim no sai dua hauv kev tshawb xav dua li lub SATA interface uas tus tsav tsheb nyob rau sab nrauv qhib siv. Qhov ntau yog vim tias cov nyiaj siv ua haujlwm ntawm kev hloov kho, qhov newer USB tseem tseem qeeb qeeb, tiam sis feem ntau ntawm cov neeg siv, yuav luag tsis muaj qhov txawv. Vim li no, eSATA connectors tsis tshua muaj ntau tam sim no thaum siv USB-raws li cov ntaub ntawv muaj ntau ntau yooj yim.
Cov lus xaus
Sab nraud SATA yog lub tswv yim zoo thaum nws xub tuaj. Qhov teeb meem yog tias SATA interface muaj yeej tseem tsis tau hloov ntau xyoo. Vim li ntawd, sab nraud interfaces tau ua sai npaum li qhov chaw ceev cia. Qhov no txhais tau hais tias eSATA tsis tshua muaj ntau thiab tsis yog siv tiag tiag rau hauv ntau cov computers txhua txhua lub sijhawm. Qhov no yuav hloov yog hais tias SATA Express ntes tab sis qhov no tsis yog lub ntsiab lus tias USB yuav yog qhov tseem muaj peev xwm sab nraud cia rau ntau xyoo tuaj.
