I-PC yokuSebenza yangaphandle yeSitoreji ngokusekelwe kwiMigangatho ye-SATA
I-USB kunye ne-FireWire bobabini babe yinto enkulu yokugcina isitoreji sangaphandle, kodwa ukusebenza kwabo kuqhathaniswa ne-desktop drives kuye kwalahla emva. Ngokuphuhliswa kweendlela ezintsha ze-Serial ATA, ifomathi entsha yokugcina yangaphandle, i-Serial yangaphandle ye-ATA, sele iqalisa ukungena kwiimarike. Eli nqaku liza kubheka isixhobo esibonakalayo esitsha, ukuba siyayilinganisa njani amafomathi akhoyo kunye nokuba ungathini ngokubhekisele kwangaphandle.
I-USB ne-FireWire
Ngaphambi kokujonga i-external Serial ATA okanye i-eSATA interface, kubalulekile ukujonga kwi-USB kunye ne-FireWire interfaces. Zombini ezi zinto zidibeneyo zenziwe njenge-interfaces ezikhawulezayo ze-serial phakathi kwenkqubo yekhomputha kunye nemipheripherya yangaphandle. I-USB iqhelekileyo kwaye isetyenziselwa uluhlu olubanzi olubanzi lweefowuni, ii-mouse, i-scanners kunye nabaphrinta ngexesha i-FireWire isetyenziswe kuphela njengendlela yokugcina yangaphandle.
Nangona ezi zixhobo zisetyenziselwa ukugcinwa kwangaphandle, iimoto ezisetyenziswayo kwezi zixhobo zisasebenzisa i- interface ye-SATA . Oko kuthetha ukuthini i-enclosure yangaphandle enezindlu ezilukhuni okanye i-optical drive ene-bridge eguqula iimpawu ukusuka kwi-USB okanye kwi-FireWire isikhombisi kwi-SATA isikhombisi esetyenziswa yi-drive. Le nguqulelo ibangela ukutshabalalisa kwintsebenzo jikelele ye-drive.
Enye yeenzuzo ezinkulu ezo zombini ezi zinto ziphunyeziweyo ziyikhono elitshintshisayo. Izizukulwana zangaphambili zendawo yokugcina indawo azizange zixhase amandla okuqhuba okanye ukukhenxiswa kwindlela. Le nto yodwa yintoni eyenza ukuthengiswa kwemakethe yangaphandle.
Enye into enomdla enokufumaneka kwi-eSATA yi-multiplier port. Oku kuvumela ikhonkco enye ye-eSATA ukuba isetyenziswe ukudibanisa isikhokhelo sangaphandle se-eSATA esinikezela ngeendlela ezininzi. Oku kunokwenza ukugcinwa okukhulayo kwisitya esinye kunye nokukwazi ukugcina isitoreji esipheleleyo nge- RAID .
eSATA vs. SATA
I-Aerial yangaphandle ye-ATA empeleni i-subset yeenkcukacha ezongezelelweyo kwi-serial ATA standard interface. Akuyena umsebenzi ofunekayo, kodwa ukongezwa okunokungeniswa kokubili umlawuli kunye nezixhobo. Ukuze i-eSATA isebenze kakuhle zombini kufuneka isekele iimpawu ze-SATA eziyimfuneko. Oku kubaluleke kakhulu kubaphathi abakuqala beSATA nabaqhubi abakwazi ukuxhasa i-Hot plug inamandla ebalulekileyo yomsebenzi wangaphandle.
Nangona i-eSATA inxalenye yenkcazo ye-SATA yoqwalaselo, isebenzisa isixhobo senyama esivela kwii-connectors zangaphakathi ze-SATA. Isizathu salokhu kukukhusela kangcono ilayini ye-serial yecala ekhutshwe ngayo ukuthumela iisayina kwi-EMI yokukhusela. Ikwabonelela nge-2m ububanzi bekhebula ngobude obuqhathaniswa ne-1m yezixhobo zangaphakathi. Ngenxa yoko, iintlobo ezimbini zeekhebula azikwazi ukusetyenziswa ngokuchanekileyo.
Ulwahlulo lwezantya
Enye yeenzuzo eziphambili ezinikezelwa yi-eSATA ngaphezu kwe-USB kunye ne-FireWire isantya. Nangona ezinye iimbini ziphezulu ukusuka ekuguquleni uphawu phakathi kobumbano lwangaphandle kunye nokuqhuba kwangaphakathi, i-SATA ayinayo le ngxaki. Ngenxa yokuba i-SATA yinkqubo ejongene nokusetyenziswa kwamanzi amaninzi amaninzi, i-converter elula phakathi kwezixhumano zangaphakathi nangaphandle zifuneka kwizindlu. Oku kuthetha ukuba ifowuni yangaphandle kufuneka isebenze ngejubane elifanayo njenge-SATA drive yangaphakathi.
Ngoko ke, nasi isiviniselo seendlela ezahlukeneyo:
- I-USB 1.1 - 15 Mbps
- FireWire (1394a) - 400 Mbps
- USB 2.0 - 480 Mbps
- I-FireWire 800 (1394b) - 800 Mbps
- I-SATA 1.5 - 1.5 Gbps
- SATA 3.0 - 3.0 Gbps
- USB 3.0 - 4.8 Gbps
- USB 3.1 - 10Gbps
Kufuneka kuqatshelwe ukuba imigangatho ye-USB entsha ihamba ngokukhawuleza kwinkolelo ye-SATA ekuqhubekeni kokungena ngaphandle. Le nto yukuthi ngenxa yokuguqula izibonakaliso, i-USB entsha iyakuthi ihambe kancane kodwa kubathengi abaninzi, akukho phantse. Ngenxa yoko, izixhumi ze-eSATA zizona ziqhelekileyo ngoku ngokusebenzisa i-USB-based based entries.
Izigqibo
I-SATA yangaphandle yayingumcamango omkhulu xa iphuma kuqala. Ingxaki kukuba i-interface ye-SATA ayizange ishintshwe kwiminyaka emininzi. Ngenxa yoko, i-interfaces zangaphandle sele ihamba ngokukhawuleza kunokuba i-drive yokugcina. Oku kuthetha ukuba i-eSATA ayifani ngokuqhelekileyo kwaye ingasetyenziswa ngokupheleleyo kwiikhomputha ezininzi kuzo zonke. Oku kungatshintsha ukuba i- SATA Express ibambelele kodwa oku akunakuchaza ukuba i-USB mhlawumbi iya kuba yinkcazo yokugcina yangaphandle yokugcinwa kweminyaka kwiminyaka ezayo.
