- Kuyini i-eSATA: isandiso se-SATA sangaphandle sesitoreji, ngaphandle kokuguqulwa kwesignali kanye nezixhumi ezenzelwe ukunciphisa ukuphazamiseka.
- Izinzuzo: ukudluliselwa okusheshayo nokuzinzile kune-USB 2.0, ukuxhuma okusheshayo, kanye nokusekelwa kwama-drive amaningi ngama-multiplier.
- Imikhawulo kanye nekusasa: ukuntuleka kwamandla ahlanganisiwe, izintambo ezikhawulelwe ku-2 kanye nokushintshwa yi-USB 3.x/USB-C; namuhla ziwusizo kakhulu kuma-niches kanye nehadiwe endala.
Ubuchwepheshe buthuthuka ngokwedlulele, futhi kanye nakho, izindlela zokudlulisa idatha phakathi kwamadivayisi nazo ziyayenza. Obunye balobu buchwepheshe, nakuba bungaziwa kangako uma buqhathaniswa ne-USB, yichweba eSATA. Leli zinga, nakuba lingavamile namuhla, linikeze izinzuzo ezibalulekile ngaleso sikhathi futhi lihlala liwusizo ezimweni ezithile.
Uma uke wezwa nge- eSATA kodwa usazibuza ukuthi iyini nokuthi ingaba kanjani inketho yokuxhuma amadivayisi esitoreji sangaphandle, ufike endaweni efanele. Sizohlukanisa yonke imininingwane, kusukela endleleni esebenza ngayo kuya ezinzuzweni zayo kanye nemikhawulo yayo, ukuze uqonde ukubaluleka kwayo kanye nokusetshenziswa kwayo okungenzeka.
Yini i-eSATA?
I-External Serial Advanced Technology Attachment , eyaziwa ngokuthi i-eSATA , iyisandiso se-SATA standard. Yakhelwe ngokuyinhloko ukuxhuma amadivayisi esitoreji sangaphandle, le port ivumela ukudluliselwa kwedatha okusheshayo nokuphumelelayo ngaphandle kwesidingo sokuguqulwa kwesignali.
Ngokungafani ne -USB noma i-FireWire , i-eSATA ayiguquli amasignali phakathi kwesixhumi sangaphandle sedivayisi kanye nesistimu, okunciphisa kakhulu ukulahleka kwesivinini. Isebenzisa isixhumi esithile esihlukile ngokubonakalayo kusixhumi sangaphakathi se-SATA , esinikeza isivikelo esingcono ekuphazamisekeni kwe-electromagnetic futhi ivumela ubude obukhulu bekhebula obufika kumamitha amabili.
Izinzuzo ze-eSATA port
Phakathi kwezinzuzo eziyinhloko ezazibeka i -eSATA ngokumelene nezinye izixhumi kwakuwukushesha kwayo kokudlulisa kanye nokuzinza. Yayinikeza amazinga afinyelela ku-3 Gbps uma kuqhathaniswa nama-480 Mbps e -USB 2.0 ngaleso sikhathi, okwakubalulekile kulabo ababedinga ukusebenza ngedatha enkulu, njengabahleli bamavidiyo kanye nabaklami bezithombe.
Enye inzuzo ephawulekayo kwakuwukukwazi kwayo ukushintshashintshana kwe-hot , okusho ukuthi amadivayisi angaxhunywa noma anqanyulwe ngaphandle kokuvala uhlelo. Ngaphezu kwalokho, i-port multiplier ku- eSATA ivumele isixhumi esisodwa ukufinyelela amadrayivu amaningi ku-array, okwakuwusizo ekulungiselelweni kwesitoreji okuthuthukisiwe njenge -RAID.
Umehluko phakathi kwe-eSATA, i-USB ne-FireWire
Nakuba i-USB iyinto ebanzi kakhulu futhi isetshenziselwa ukuxhumanisa izinhlobo eziningi zezinto ezisetshenziswayo, njengegundane, amaphrinta, namakhibhodi, i-eSATA ibonakale isebenza kahle kakhulu kwisitoreji sangaphandle . Lokhu kungenxa yokuthi igweme isidingo sokuguqulwa kwesiginali, isici esivamile se -USB kanye ne -FireWire interfaces , esonakele ukusebenza.
Nakuba i-FireWire yayiyindlela ethandwayo yokugcina idatha yangaphandle, yayingakwazi ukuncintisana ngesivinini kanye nokuzinza nezixazululo ezinikezwa yi -eSATA . Isibonelo, ngenkathi i-FireWire 800 ifinyelela ku-800 Mbps, i-eSATA yayivele isebenza ngesivinini esingu-1.5 kuya ku-3 Gbps, kuye ngokuthi i-SATA isetshenziswa kanjani.
Ukuqaliswa nokuhambisana
Amachweba e-eSATA aqala ukusetshenziswa cishe ngo-2004 futhi ngokushesha aba inketho ekhangayo kubakhiqizi bamadivayisi okugcina amakhompyutha nawangaphandle. Nakuba ukusetshenziswa kwawo kwakulinganiselwe, ama-hard drive amaningana angaphandle nama-motherboard afake lobu buchwepheshe, ikakhulukazi ekucushweni okuphezulu.
Kodwa-ke, ukuntuleka kwamandla ahlanganisiwe kukhebula le -eSATA kwakuwumkhawulo omkhulu. Amadivayisi amaningi ayedinga izinsiza zamandla ezihlukene, okuvimbela ukuphatheka kalula. Lokhu kwaholela ekuthuthukisweni kwezindinganiso ezifana ne -Power over eSATA , ezihlanganisa idatha namandla zibe ikhebula elilodwa.
Ukusetshenziswa okuvamile kwembobo ye-eSATA
I -eSATA port yayisetshenziswa kabanzi ukuxhuma ama-hard drive angaphandle, ikakhulukazi ezindaweni zobungcweti ezazifuna isivinini sokudlulisa esiphezulu . Kwakuyinketho ekhethwayo futhi ezinhlelweni zokuphepha, lapho ukucushwa kwe-RAID yangaphandle kwakubalulekile ekuphatheni idatha eningi ngesikhathi sangempela.
Nakuba ukusetshenziswa kwe-eSATA kwehlile, amanye ama-adapter akuvumela ukuthi uguqule ama-port e-SATA angaphakathi abe ama-port e-eSATA angaphandle . Lokhu kwandisa ukusebenza kwawo futhi kuhlala kuwusizo kulabo abanehadiwe endala ehambisanayo. Uma udinga ukukhetha isitoreji, bheka iziqondiso kuma -hard drive angaphandle ukuze uthole okuningi kuwo.
Imikhawulo ye-eSATA
Naphezu kwezinzuzo zayo, i-eSATA yayinemikhawulo yayo. Okusobala kakhulu kwakuwukuntuleka kwamandla ahlanganisiwe ezintanjeni zayo ezijwayelekile, okwaba nzima ukusetshenziswa kwamadivayisi angaphandle ngaphandle komthombo wamandla owengeziwe. Nakuba i-Power over eSATA yayixazulula kancane le nkinga, ayizange ifinyelele ekwamukelweni kabanzi.
Ngaphezu kwalokho, ubude obukhulu bekhebula obungamamitha ama-2 bukhawulelwe ukuguquguquka kokuxhumeka uma kuqhathaniswa ne -USB noma i-FireWire , okuvumela izintambo ezinde kakhulu. Ekugcineni, ngokufika kwe -USB 3.0 kanye ne-USB-C , ezinikeza isivinini esiphezulu kanye nokuguquguquka okukhulu, i-eSATA yaphelelwa yisikhathi. Ukuqonda umehluko phakathi kwama-hard drive angaphakathi nangaphandle kungakusiza ukuthi uhlole ukufaneleka kwawo.
Ikusasa le-eSATA
Amachweba e-eSATA awasasetshenziswa kakhulu ngenxa yokusetshenziswa kabanzi kobuchwepheshe obuthuthukisiwe njenge- USB 3.1 kanye ne-3.2 . Kodwa-ke, ungase uwathole kwezinye izilungiselelo ezikhethekile noma kwihadiwe endala ehlala isebenza.
Nakuba i-eSATA idlale indima ebalulekile ngesikhathi sayo, ukubaluleka kwayo kwamanje kulele kakhulu ezindaweni ezithile. Uma unezingxenye ezihambisana nalokhu kuxhumana futhi udinga ukuzisebenzisa ngokugcwele, ukuhlola ama-adapter noma ukucushwa kwe -USB okuhlanganisiwe kungaba yisisombululo esisebenzayo.
I-eSATA iphawule uguquko ekuthuthukisweni kwezixhumi zokuxhumeka zesitoreji sangaphandle. Nakuba ukusetshenziswa kwayo kulinganiselwe namuhla, kusalokhu kuwubufakazi bendlela ubuchwepheshe obuthile obunganikeza ngayo izixazululo eziphumelelayo ezifanela izidingo zamanje.
