ESATA - yintoni na? Iintlobo kunye neentlobo ze-eSATA

Namhlanje isango le-eSATA liye layeka ukuba into entsha ngokwenene. Nangona kunjalo, kulo mzekelo, akubona bonke abasebenzisi baqhelana nayo kwaye abacacanga ngokucacileyo ukuba ziphi iingenelo kunye nokungahambi kakuhle ezi nikelwe ngumgangatho kumsebenzi wemihla ngemihla ngekhompyutha.

Ncinane malunga neSATA

Ewe, abaqalayo baya kuba ngabokuqala abanomdla ekufundeni iSATA - yintoni na kwaye idliwe ngayo. Ukuba uzama ukuphendula ngokulula, ke lo mgangatho wecandelo lokungena kwi-port likho kwizantya kunye nokukhululeka kokusetyenziswa kwindawo ethile phakathi kwe-USB2.0 kunye ne-SATA yendabuko. Eli gama ngokwayo linomxholo wesigxina se-Outdoor Serial ATA, oko kukuthi, ichweba esebenzisa ubuchwepheshe obuphambili bokutshintshiselana kwedatha kwaye linako ukutshintshisa utshintshi kokubili ukuqhuma kanzima kunye nezinye izixhobo ezixhunyiwe kwikhomputha.

Nangona u-eSATA-uqhagamshelwano lwavela ngo-2004, namhlanje ngokuqhelekileyo abasebenzisi bakhetha ubuchwepheshe bendabuko obuninzi - i-USB kunye ne-SATA.

Inzuzo

Ewe, umgangatho we-eSATA awuyi kuhanjiswa, ukuba wawungenayo inzuzo. Ezi ziquka:

• Inokwenzeka yokwandisa ikhebula yokudluliselwa kwedatha ukuya kwi-2m mitha ngaphandle kwengozi yokuphazamiseka kwesignali;
• Ukubonisana kweSATA kunye neSATA;
• Ukudluliswa kwedatha okukhawulezileyo kuqhathaniswa ne-USB2.0;
• Ixabiso eliphantsi kwimveliso livumela ukuxhobisa i-chipsets ngeendawo ezininzi ze-eSATA kunye nokusetyenziswa kwesi sixhobo kwiinkcukacha ezininzi. Umzekelo, kukho i-drive yangaphandle ye-eSATA kunye ne-USB flash drive;
• Iidiski ezinzima zinokudibaniswa kwiipaki ze-RAID;
• Kuyakwazi ukutshintsha iidiski ezinzima ekuhambeni, okungenakucingeka ukuba unikezelo oluqhelekileyo lwe-SATA lusetyenziswa.

Njengoko uyakubona, izibonelelo zalo mbonakalo zivame, ubuncinane xa kuthelekiswa nemigangatho eqhelekileyo neqhelekileyo njenge-USB2.0 ne-SATA.

Iingxaki

Ukuphendula umbuzo, i-eSATA - oko kukuthi, awukwazi ukuyihoxisa ukungahleleki kwalo hlobo loxhumano. Nangona kunjalo ukuba lolu hlobo lwenkqubo luqaliswe ngo-2004, akuzona zonke izixhobo ezixhotyiswe ngamachweba alo mgangatho, kwaye ngoku ukusetyenziswa kwayo kunzima ngenye iingxaki:

• Ukungahambelani komzimba kwii-port e-eSATA ne-SATA;
• Isantya sokutshintshiselana kwedatha sisesezantsi kuneSATA. Imivavanyo emininzi yokudibanisa isiqinisekisile oku;
• Ubungakanani bekhebula bukhawulelwe kumitha ezimbini, engaphantsi kwimeko ye-USB;
• I-hard drive ye-ESATA iya kufuna amandla angaphezulu nge-USB kunye no-1394 okanye ngokusebenzisa i-standard standard (kwiimodeli ezintsha zamashishini zangaphandle ezifana nesidingo sinyamalalala);
• I-ESATA kunye ne-SATA basebenzise amaqondo ahlukeneyo;
• Umbutho we-ESATA ngezinye iinkhathi ufuna umlawuli okhethekileyo kwibhodi ye-motherboard;
• Kuze kube ngoku, akukho zixhobo ezininzi ezikhutshwe eziya kuxhasa le mgangatho.

Ngokubhekiselele kwinqanaba lokutshintshwa kwedatha ngokwalo, i- eSATA iphelelise ngokubanzi umgangatho we-USB 2.0 kule nkalo, kodwa iphantsi kwe-USB 3.0 yanamhlanje. Mhlawumbi, nantoni na edibeneyo nale yinyaniso yokuba izixhumi ze-eSATA azidume namhlanje: emva koko, kulula ukusebenzisana ne-USB, kwaye isantya kwi-version 3.0 iphezulu.

Iintlobo ze-eSATA

Okumangalisa ngokwaneleyo, esi sikhombiselwano sineendidi zayo. Nangona kunjalo, a baninzi kubo. Okanye, zimbini kuphela:

1. Ngokwenene eSATA, malunga nempawu ezikhankanywe ngasentla.
2. I-ESATAp iyimpawu ehlukile yalolu hlobo lwechweba kwinto yokuba yenzeke ukuba ifowuni iqhutywe ngqo kwi-cable ye-eSATA, i-SATA nayo ifuna ukunikezela amandla ngaphandle komthombo ongaphandle. I-Postfix iphelela amandla.

Kubonakala ngathi ngokuza kwe-standard standard njenge-eSATAp, zonke iingxaki zazisombululwa, kwaye eli lichweba lilungele ukuzomeleza. Kodwa ke i-USB 3.0 yafika, kwaye i-eSATAp ayikwazanga ukukhuphisana nayo.

Kwaye kunye ne-12 volts

Nangona kunjalo, unako ukudibanisa nayiphina idivayisi ye-USB kwisango le-eSATA. I-Interfaces ikuvumela ukuba wenze oku. Ngethuba elifanayo, kuya kubakho ukucwangciswa ngokufanayo kweso sixhobo kunye nokudluliswa kwedatha kuzo zombini iziphelo.

Ingxaki ebalulekileyo kulo mzekelo kukuba ezinye iimodeli zokuqhuba kanzima azidingi kuphela ii-volts ezi-5 eziqhelekileyo zokwenza, kodwa zininzi ezili-12. Yingakho i-eSATAp iphuculwe inguqu ephuculweyo, enika oonxibelelwano bamandla abongezelelweyo kwisixhobo. Isixhobo esibonakalayo sasibizwa ngokungekho mthethweni eSATAdp, esona sikhulu samandla.

Ukuba akukho iSATA

Ngexesha elide, kodwa ngamanye amaxesha kufuneka uvelise i-eSATA ifowuni kuphela ngesango le-SATA kwibhodi ye-motherboard. Umzekelo, ukuba ufuna ukudibanisa iSATA yangaphandle kwisixhobo.

Unokwenza oku, kodwa oku kufuna i-cable extension extension edibanisa ngqo kwi-SATA kwibhodi ye-motherboard. Ukuba sithetha nge laptop okanye netbook, ke le nxu lumano luyenzeka nge-PC Card adapters, nakwiKharity Express. Kodwa kule meko ubude obude bekhebula buya kugqitywa kumitha enye nje, engekho rhoqo.

Izixhobo zangaphandle kunye nenkxaso ye-eSATA

Ngesinye isikhathi, ngaphambi kokufika kwe-USB 3.0, umboniso we-eSATA kulindeleke ukuba ube nekamva eliqaqambileyo. I disk yangaphandle i-eSATA ingafumaneka kwintengiso ngoku. Emva kwakho konke, i-USB 3.0 ayikazanga ukukhupha i-USB 2.0 yayo yonke indawo.

Kwaye ekubeni isiseko se-eSATA senzelwe ngokukodwa ukutshintshiselana kwedatha okukhawulezayo, kunengqiqo ukuba isabelo seengonyama kwiimpahla zangaphandle ezixhasa le mbonakalo, zonke iintlobo zokuqhuba. Ezi ziqhube zangaphandle kunye nokuhamba kwefayili. Kodwa unokufumana kwakhona ekuthengiseni nakwabashicileli kunye nabaskena, abasebenzisa olu hlobo loxhumano.

Ngelishwa, ukudideka okunxulumene nobukho bezinto ezincinci kodwa iintlobo ezahlukeneyo ze- SATA, i- eSATA, eSATAp, kunye ne-eSATAdp, uye wabangela abathengi ukuba badideke kunye ne-port kunye ne-cable. Kwaye kunye ne-adapter ye-eSATA ayisoloko isinceda ukuyicombulula le ngxaki, ingakumbi ukuba ubunzima abuhambelananga kuphela nokuhambelana, kodwa kunye nesidingo sokwenza i-recharge eyongezelelweyo (i-12 volts efanayo). Ukongezelela, umgangatho we-eSATAdp awunakunikwa.

Ngoxa kuhleli nje ukubeka iliso ngokufanelekileyo ukulandelelana kweentambo, ukuze ungadibanisi ikhebula eSATA, SATA nabanye. Kwaye sinethemba lokuba konke oku kufikeleleke kumgangatho oqhelekileyo, okanye iindidi zee-SATA ziza kutshintshwa ngeprothi enye.

Kutheni ungafaki umlilo okanye i-USB

Ngokuqinisekileyo, impendulo yombuzo malunga neSATA - ukuba yintoni, ayikwazi ukuqwalaselwa ingagqibekanga ngaphandle kokuzama ukuhlalutya amathuba kwiincutshu. Kule meko, FireWire ne-USB.

Kwaye nezizathu zokuba kungani i-eSATA ingatshintshwanga ngabo ngoku, ezintathu:

1. Ukuhlela ukutshintshiselana kwedatha ngokusebenzisa ezi zibuko ezimbini, kufuneka uguqule ii-protocol ze-PATA okanye ze-SATA kwi-USB okanye i-FireWire efanayo. Nangona kunjalo, i- bandwidth inezinciphiso ezibalulekileyo. Le nto yayingabonakali kakhulu kwiintsuku zakudala, nangona kunjalo, ngokubonakala kweefowuni zokugcina izinto ezisisigxina ngokubanzi ukusuka kwi-500 GB, okwangamangalanga namnye umntu namhlanje, loo mbundu yabonakala kakhulu.
2. Isizathu sesibini kukuba nokuba kwimeko ye-FireWire, kukho umda wokukhawuleza ukudluliswa kwedatha kwama-400 Mbps, kuba abalawuli be-FireWire basebenze ngokwemilinganiselo ye- IEEE 1394A. Nanku imingcele enjalo ayibonakali kakhulu ekusebenziseni iitshini ezikhuni ezinkulu, zingaphi izantya eziphakamileyo, kunye neendawo ezinkulu ze-RAID, eziyimfuneko kakhulu, ezifuna ukukhawuleza.
3. Ekugqibeleni, ii-drives ezisekelwe kwi-FireWire ne-USB azikwazi ukufikelela kwezinye iindawo eziphantsi. Umzekelo, kumsebenzi we-SMART Ngelo xesha, i-eSATA isilondoloze le ntsilelo.

Nangona i-interfaces ezikhuphisanayo zithandwa kakhulu kubasebenzisi abaqhelekileyo ngenxa yokuhamba kwazo, nangona kunjalo, kwezinye iimeko, akukho ndlela yokwenza ngaphandle kwe-interface ye-eSATA. Ngoko ke, ukuba umsebenzisi ufuna isivinini esikhulu sokudluliswa kwengcaciso yomthamo omkhulu, lo mgangatho uza kuba sisisombululo esihle kulolu hlobo lwemisebenzi. Ngelishwa, ukuphunyezwa kwayo kubandakanya ubunzima bezobugcisa, kodwa ngamandla angaphezulu, umzekelo, ukusebenzisa i-unit yangaphandle, oku akuyi kuba yingxaki.

ESATA Outlook

Nangona kunzima ukwamukelwa nantoni na ngesiqinisekiso esingu-100% malunga nekamva kule interface. Kodwa ngaphandle kokuzama ukuqikelela xa uphendula umbuzo malunga ne-eSATA - oko kukuthi, akunakwenzeka.

Nangona kukho iifowuni kwiimarike ezixhasa ukusebenzisana namachweba ezifana ne-USB 2.0, i-USB 3.0, kunye ne-FireWire apha ngentla, ikusasa le-eSATA aliqinisekanga. Ngakolunye uhlangothi, abakhiqizi abazisebenzisi ngokukhawuleza ukusebenzisa le port kwizo zonke izixhobo zabo, nangakolunye uhlangothi baqhubeka bevelisa ukuqhutshwa kweso sikhombisi, kodwa abayikulibala nge-USB 3.0 nokuba kunjalo.

I-ESATA ibonakala kakuhle ukuba ufuna, umzekelo, ukuxhuma amacebo amakhulu okugcina okanye ukuphatha umxholo we-multimedia njenge-HD. Kwakhona lo mboniso uza kunceda wonk 'ubani ofuna ukuba ne-RAID yakhe yokuhlala ekhaya.

Kodwa abasebenzisi abaninzi baya kukhetha ukusebenzisa umsebenzi wabo wemihla ngemihla kwaye bahamba ngokukhawuleza, kodwa kubonakala lula kunye nenembile, njengesi-USB 2.0. Emva koko, uninzi lwawo aludingeki ukuba lusebenze ngokuqhuba ngokukhawuleza kunye nolwazi olunamandla, ngaphezu koko, ngokuqhelekileyo abasebenzisi banqanyanyiswa yimfuneko yokongeza amandla ngefowuni nge-interface ye-eSATA. Bakulungele ukubeka ezinye izithintelo kwijubane ngenxa yokulula. Kodwa kwezinye iimeko akunakwenzeka ukwenza ngaphandle kwayo.

Ngoko, akufanele silindele ukuba i-interface ye-eSATA ibe nefuthe kwiimarike kwixesha elizayo, kodwa ayiyi kukhawuleza okanye mhlawumbi, ngenxa yokuba imfuno yalo ikhona.

Iingcali ezininzi zithetha ukuba lo mgangatho uza kusinda de ukusasazeka kwimiqathango emitsha yamanje, okanye ekugqibeleni igcine i-USB 3.0. Nangona kunjalo, nje kuphela oku kungenzeki, unako ukuthenga ngokukhuselekileyo ii-drive ezisebenzayo ngesiseko se-eSATA.
