I-PC Yokungena Isitoreji Esingaphandle Isisekelo Esisekelwe Ezizindeni ze-SATA
I-USB ne-FireWire boba bobabili babe yisimiso esikhulu sokugcina isitoreji sangaphandle, kodwa ukusebenza kwabo kuqhathaniswa namashayela wedeskithophu bekulokhu kusala ngemuva. Ngokuthuthukiswa kwamazinga amasha we-Serial ATA, ifomethi entsha yokugcina yangaphandle, i-Serial ATA yangaphandle, manje isiqala ukungena emakethe. Lesi sihloko sizobuka isikhombikubona esisha, ukuthi siqhathanisa kanjani namafomethi akhona kanye nokuthi singasho ukuthini ngokugcina isitoreji sangaphandle.
I-USB ne-FireWire
Ngaphambi kokubuka i-Serial ATA yangaphandle noma isikhombimsebenzisi se-eSATA, kubalulekile ukubuka ukungena kwe-USB ne-FireWire. Zombili lezi zinkimbinkimbi zenzelwe ukuxhumana okusheshayo kwe-serial phakathi kwendlela yekhompiyutha nezingcingo zangaphandle. I-USB iningi futhi isetshenziselwa ububanzi obubanzi bezingcingo ezifana namakhibhodi, amagundane, amaskena kanye namaphrinta ngenkathi i-FireWire isetshenziswa kuphela njenge-interface yangaphandle yokugcina isitoreji.
Ngisho noma lezi zinkimbinkimbi zisetshenziselwa isitoreji sangaphandle, ukushayela kwangempela okusetshenziswe kula madivayisi kusasebenzisa i- interface ye-SATA . Lokho kusho ukuthinta okungaxhunyiwe kwangaphandle okwakhiwa idrayivu eyinkimbinkimbi noma ebonakalayo ibhuloho eliguqula amasignali kusuka ku-USB noma ku-FireWire isikhombimsebenzisi ku-interface ye-SATA esetshenziswa yi-drive. Le nguqulo ibangela ukulimala ekusebenzeni jikelele kwedrayivu.
Enye yezinzuzo ezinkulu zombili lezi zindlela ezihlanganisiwe ezisebenzayo kwakuyikhono elishisayo elishisayo. Izizukulwane ezedlule zokuxhumana ezigcinwe ngokuvamile azizange zisekele ikhono lokushayela ngokunamandla noma lisuswe ohlelweni. Lesi sici sodwa senza ukuthi imakethe yesitoreji yangaphandle iqhume.
Esinye isici esithakazelisayo esingatholakala nge-eSATA yi-multiplier port. Lokhu kuvumela isixhumi esisodwa se-eSATA ukuthi sisetshenziselwe ukuxhuma i-chassis yangaphandle ye-eSATA enika amashayeli amaningi ku-array. Lokhu kunganikeza isitoreji esandisekayo ku-chassis eyodwa kanye nekhono lokuthuthukisa isitoreji esiphelele nge- RAID .
ISATA vs. SATA
I-External Serial ATA empeleni i-subset yezincazelo ezengeziwe ze-standard Serial ATA interface. Akuwona umsebenzi odingekayo, kodwa isandiso esingangezwa kokubili isilawuli namadivayisi. Ukuze i-eSATA isebenze kahle kokubili kumele isekele izici ze-SATA ezidingekayo. Lokhu kubaluleke kakhulu njengabalawuli be-SATA abadala bokuqala kanye namashayela awasekeli amandla e-Hot Plug obaluleke kakhulu ekusebenzeni kwesikhombimsebenzisi sangaphandle.
Yize iSATA iyingxenye yezincazelo ze-SATA esibonakalayo, isebenzisa isixhumi esibonakalayo esivela kakhulu ezixhumi zangaphakathi ze-SATA. Isizathu salokhu ukuvikela isihluthulelo kangcono imigqa ye-serial serial esetshenziselwa ukudlulisela izimpawu kusuka ekuvikelweni kwe-EMI. Ibuye inikeze ubude bekhebula lobubanzi obuyi-2m uma kuqhathaniswa no-1m wezintambo zangaphakathi. Ngenxa yalokho, izinhlobo ezimbili zekhebula azikwazi ukusetshenziswa ngokungafani.
Ukungafani Kakhulu
Enye yezinzuzo eziyinhloko iSATA ezinikeza ngaphezu kwe-USB ne-FireWire ngesivinini. Ngenkathi ezinye ezimbili ziphezu kokuguqula isignali phakathi kwesibonakaliso sangaphandle kanye nezinjini zangaphakathi, i-SATA ayinayo le nkinga. Ngenxa yokuthi i-SATA iyisimo esibonakalayo esivamile esetshenziswa kuma-drive amaningi amasha, i-converter elula phakathi kwezixhumi zangaphakathi nezingaphandle zidingeka ezindlini. Lokhu kusho ukuthi idivayisi yangaphandle kufanele igijime ngesivinini esifanayo njengedrayivu yangaphakathi ye-SATA.
Ngakho, nansi ukuvinjelwa kwezixhumanisi ezahlukene:
- I-USB 1.1 - 15 Mbps
- I-FireWire (1394a) - 400 Mbps
- I-USB 2.0 - 480 Mbps
- I-FireWire 800 (1394b) - 800 Mbps
- I-SATA 1.5 - 1.5 Gbps
- I-SATA 3.0 - 3.0 Gbps
- I-USB 3.0 - 4.8 Gbps
- I-USB 3.1 - 10Gbps
Kumele kuqashelwe ukuthi amazinga we-USB amasha manje asheshayo kunombono we-interface we-SATA wokuthi ukushayela okusetshenziselwa ukungena kwangaphandle. Into yukuthi ngenxa ye-overhead yokuguqula izimpawu, i-USB entsha izobe isancipha kancane kodwa kubathengi abaningi, cishe akukho umehluko. Ngenxa yalokhu, izixhumi ze-eSATA azivami kakhulu manje njengoba kusetshenziswa izinsimbi ze-USB ezilula kakhulu.
Iziphetho
I-SATA yangaphandle yayingumqondo omuhle lapho iphuma kuqala. Inkinga yukuthi isikhombimsebenzisi se-SATA asinakushintshwa eminyakeni eminingi. Ngenxa yalokho, ukuxhumana kwangaphandle kuvele ngokushesha kakhulu kunamashayela okugcina. Lokhu kusho ukuthi i-eSATA ayitholakali kakhulu futhi empeleni ayisebenzisi ngempela kuma-computer amaningi nhlobo. Lokhu kungashintsha uma i- SATA Express ibambelela kodwa lokhu akusho ukuthi kungenzeka ukuthi i-USB izoba isikhombimsebenzisi esibonakalayo sokugcina isitoreji seminyaka eminingi ezayo.
