ESATA - kuyini? Izinhlobo kanye eSATA

Namuhla eSATA port Sekuyisikhathi eside saphela into entsha ngempela futhi ezingavamile. Nokho, akubona bonke abasebenzisi bajwayelene ke bese ungacabangi ngokucacile lokho emihle nemibi le ndinganiso inikeza emsebenzini nsuku zonke ne-computer.

Okuncane eSATA

Yiqiniso, Wabasaqalayo kuyoba ikakhulukazi ukwazi, eSATA - lokho oyikho nalokho ibadla. Uma uzama ukuphendula elula, le ndinganiso port serial itholakala isivinini kanye lula ukusetshenziswa endaweni ethile phakathi bendabuko kanye USB2.0 ejwayelekile Sata. I ukuqaqwa eside kuyinto esifushanisiwe sangaphandle ATA yomkhiqizo, okuyi-port, ngokusebenzisa izinto zobuchwepheshe obuphambili zokuxhumana idatha serial nokuba nekhono "hot" esikhundleni epheshaneni njengendlela drive kanzima, namanye amadivayisi exhunywe computer.

Naphezu kweqiniso lokuthi eSATA-uxhumano wafika ngo-2004, namuhla, abasebenzisi bathanda bendabuko ngaphezulu ubuchwepheshe - USB ne Sata.

isithunzi

Yiqiniso, eSATA ejwayelekile ayengangeni ukusakaza, hhayi kungakhathaliseki ukuthi kunezinzuzo bakhe umgomo. Futhi lezi zibandakanya:

• kungenzeka nokwelula ikhebula ukudlulisa idatha up 2 m ngaphandle ingozi ukuhlanekezela;
• isignali eSATA iyahambisana Sata;
• Okufinyeziwe ukudluliswa kwedatha uma kuqhathaniswa ne USB2.0;
• ezishibhile ekukhiqizeni ivumela ukuhlomisa nge chipsets amaningi futhi eSATA nezimbobo ukusebenzisa lolu jack in kumadivayisi amaningi. Ngokwesibonelo, kukhona eSATA kanzima yangaphandle drive ngisho ifleshikhadi;
• hard drive ngesikhathi esifanayo zingahlanganiswa a raid-afanayo;
• kungaba kwenziwe ukuba esikhundleni hard drive on the fly, akunakwenzeka uma enikeziwe ukusetshenziswa bendabuko Sata-interface.

Njengoba ubona, izinzuzo kusukela kule interface emaningi khona, ngisho uma ziqhathaniswa amazinga okwandile ezijwayelekile ezifana ezifana USB2.0 futhi Sata.

amaphutha

Ukuphendula umbuzo, eSATA - kuyini, asinakulishalazela ukushiyeka lolu hlobo lwe-Inthanethi. Naphezu kweqiniso lokuthi lolu hlobo esibonakalayo wasungula kusukela ngo-2004, hhayi kuwo wonke amadivayisi anemisila nezimbobo ejwayelekile, kodwa ukusetshenziswa kwalo nzima nezinkingana ezithile:

• Ukungahambisani Physical Sata futhi eSATA nezimbobo;
• Izinga Translations into Zulu namanje kancane kunalokho of Sata. Ziningi zokwenziwa ukuhlolwa isikuqinisekisile lokhu;
• ikhebula obuphelele kukhawulwe amamitha amabili, okuyinto esingaphansi endabeni le-USB;
• eSATA HDD zidinga amandla angeziwe nge-USB kanye 1394, noma ngokusebenzisa esidayisa ezivamile (imifanekiso entsha kumadivayisi angaphandle isidingo ngokuvamile ziyanyamalala);
• Sata futhi eSATA ukusebenzisa amazinga ehlukene isibonakaliso;
• ukuhlela eSATA ngezinye izikhathi kudinga isilawuli ekhethekile ebhodini uhlelo;
• okwamanje akuzona kumadivayisi amaningi esekela lesi ejwayelekile.

Ngokuqondene ijubane ukudluliswa kwedatha, le eSATA luphakeme kulesi sici manje USB sasivumela okwandile 2.0, isivuno kodwa USB yesimanje 3.0. Kungenzeka ukuthi lokhu ixhunyiwe kanye neqiniso lokuthi namuhla, eSATA nezixhumi akuzona ethandwa: phela USB ukusebenza lula futhi inguqulo isivinini 3.0 ngenhla.

izinhlobo eSATA

Isimanga siwukuthi kodwa esibonakalayo kunezinhlobo zalo siqu. Nokho, akuzona okungaka. Noma kunalokho, kwakunabesifazane ababili nje kuphela:

1. Empeleni eSATA, futhi mayelana nokuthi iziphi izinhlelo izici ezibalulwe ngenhla.
2. ESATAp - isici esasenza lolu hlobo port eliye laba kungenzeka ukuba afeze ukusuthisa amadivayisi ngqo nge ikhebuli eSATA, Sata futhi safuna saziso ugesi nge njengomthombo wangaphandle. Postfix p amandla - amandla.

Kunengqondo ukuphetha ngokuthi nge obhekwe oluvamile njenge eSATAp, zonke izinkinga zaxazululeka, kanye ne-port ilungele ukuzimela. Kodwa kufika ke mina, USB 3.0, futhi eSATAp akakwazanga ancintisane nayo.

Futhi plus volts 12

Nokho, xhuma iyiphi idivayisi ye-USB unga futhi kuya eSATA port. Interfaces uvumele lokhu. Ngakho okwenzeka ngesikhathi sinye kudivayisi ukwakheka kuzokwenzeka futhi ukudluliswa kwedatha ku ekupheleleni kokubili.

Kodwa inkinga eyinhloko kulesi simo wukuthi ezinye hard drive onobuhle zidinga hhayi kuphela standard 5 volts ukondla, kodwa amaningi njengoba 12. Kodwa ehlinzekelwe ku-laptops amandla supply yamandla enjalo. Futhi inguqulo ethuthukisiwe yasungulwa ngoba eSATAp ohlinzekela khona ezengeziwe amandla oxhumana nabo isixhumi. Interface lithole lolungakahleleki igama eSATAdp, ie ombaxambili.

Uma kungekho eSATA

Hhayi kaningi kakhulu, kodwa ngezinye izikhathi kuyadingeka ukuletha kudivayisi eSATA kuphela ebukhoneni Sata-itheku elisogwini umbadlana. Ngokwesibonelo, uma kudingeka ukuba uxhume i eSATA lwangaphandle ukuze kunoma iyiphi idivayisi.

Lokhu kungenziwa, kodwa kuzothatha yokwenziwa isandiso ikhebula ukuthi kuya Sata uxhuma ngqo umbadlana. Uma sikhuluma laptop noma netbook, umphumela uxhumano ezifana kungenzeka nge ikhadi PC adaptha, kanye ngokusebenzisa Express Card. Kodwa kulokhu, esiphezulu ikhebula obuphelele ngeke esaba imitha elilodwa nje, okuyinto zingavumi njalo.

kumadivayisi angaphandle kanye eSATA,

Ngesinye isikhathi, ngaphambi obhekwe USB 3.0, eSATA esibonakalayo okuhlala isikhathi eside ngokwanele ikusasa eliqhakazile. ESATA drive zangaphandle zingatholakala isendalini manje. Phela, USB 3.0 usengakathelwa ephethwe wokukhipha kulo yayo USB 2.0 eyandulela.

Futhi ngenxa yokuthi i-eSATA standard ukuthi ngokuyinhloko okusheshayo ukushintshanisa kwe-data, kuba impela okunengqondo ukuthi share sengonyama of kumadivayisi angaphandle esekela lesi esibonakalayo, wenze zonke izinhlobo oshayelayo. Lokhu yangaphandle hard drive, kanye flash oshayelayo. Kodwa kungatholakala ukudayiswa njengoba abaprintayo kanye scanner, ezisetshenziswa kulolu hlobo uxhumano.

Ngeshwa, amanye ukudideka ezihambisana nokuba khona ngisho encane, kodwa ukwehluka phakathi Sata esibonakalayo, i eSATA, eSATAp, futhi eSATAdp, okwaholela yokuthi abathengi basuke bexakwe ukuthi ukuhambisana nezimbobo futhi izintambo. Futhi ngisho eSATA adaptha akusho ngaso sonke isikhathi ekuxazululeni le nkinga, ikakhulukazi uma nobunzima azivumelani kuphela, kodwa futhi isidingo ukuqhuba yokudla ezengeziwe (okufanayo 12 volts). Ngaphandle eSATAdp ejwayelekile ingakamiswa zilandele izilinganiso ezithile.

Nakuba kudingeka kuphela eduze nokuqapha ukuhambisana izintambo ukuze singathwesi ukudida ikhebula eSATA, Sata nabanye. Futhi sethemba ukuthi noma wonke umuntu ekugcineni elifanele noma bayawushintsha Sata nezimbobo ukwehluka kuza ezinye port jikelele ngaphezulu.

Kunganjani ube FireWire noma USB

Yiqiniso, impendulo yombuzo ophathelene nokuthi, eSATA - kuyini, ayikwazi kubhekwe ephelele ngaphandle ngomzamo sihlaziye amathuba encintisana. Kulokhu - FireWire USB.

Futhi izizathu ukuthi eSATA Namanje hhayi ngelinye yibo, kukhona ezintathu:

1. Ukushintshanisa idatha nge lezi emachwebeni amabili, yezifiso kudingeka ukuguqula Pata noma Sata USB noma FireWire efanayo. Nokho, i-bandwidth kunezako abalulekile. Kwakungekhona kakhulu esikhathini esidlule, kodwa lapho kufika okuqinile-state drive nomthamo 500 GB, okuyinto namuhla akekho uzomangala, lokhu embundwini isibe ngempela kangako.
2. Isizathu sesibili itholakala lokuthi ukuthi ngisho esimweni kukhona umkhawulo FireWire ukuthumela idatha isilinganiso - Mbps 400 njengoba FireWire abalawuli bahlinza ejwayelekile IEEE 1394A. Lapha, kwezithibelo esinjalo abatelekile ngisho uma usebenzisa drive enkulu kanzima, kangakanani ijubane nevolumu raid-afanayo, okuyinto Yiqiniso, zidinga ngesivinini eside kakhulu.
3. Ekugcineni, oshayelayo FireWire USB based akudingeki ukufinyelela ezicini ezithile ongaphakeme. Ngokwesibonelo, umsebenzi SMART Ngesikhathi esifanayo, eSATA kokululama lokhu ethile.

Nakuba interface ukuncintisana baningi ngenxa isikhundla namalungu ifayela lula yayo, kodwa kwezinye izimo ngeke akwenze ngaphandle eSATA-interface. Ngokwesibonelo, uma umsebenzisi idinga ukudluliswa ijubane eliphezulu umthamo omkhulu kolwazi, indinganiso kuyoba yinto ikhambi ekahle ngezinkinga ezinjalo. Ngeshwa, nokuqaliswa kwalo kuhilela nobunzima ezithile zobuchwepheshe, kodwa khona amandla angeziwe, isib, i iyunithi zangaphandle, ngeke kube yinkinga.

amathemba eSATA

Nakuba kunzima ukusho lutho ngesiqinisekiso ngokuphelele ephathelene nekusasa le esibonakalayo. Kodwa ngaphandle kokuzama sezulu uma uphendula umbuzo ukuthi, eSATA - kuyini, futhi akakwazi ukwenza.

Nakuba zikhona amadivaysi emakethe ukuthi ukusekela umsebenzi nge izimbobo ezifana USB 2.0, USB 3.0, kanye ngenhla FireWire, eSATA esizayo lingaqinisekile. Ngakolunye uhlangothi, abakhiqizi akuzona ezisheshayo ngenkuthalo ukusebenzisa lolu imbobo wonke amadivayisi yayo, futhi ngakolunye - zazenzela ngemoto nale esibonakalayo, kodwa yayihlanganisa nokuthi USB 3.0 is akayikhohliwe.

ESATA kubukeka enza kahle, uma kudingeka, isibonelo, ukuxhumana wesitoreji yenqwaba noma ukucutshungulwa okuqukethwe soxhumanoningi in HD. Futhi, le interface kuzosiza wonke umuntu ukuba nomuzi wakho raid-afanayo.

Kodwa Abasebenzisi abaningi bakhetha ukusebenzisa emsebenzini wabo wansuku zonke kanye kancane, kodwa a esibonakalayo elula enembile ezifana USB 2.0. Phela, iningi lazo akudingeki sisebenze idivayisi yokulondoloza fast and capacious, ngaphezu, abasebenzisi ngokuvamile sivimbele isidingo eyengeziwe powering kudivayisi nge eSATA-interface. Bazimisele sibekezelele abanye imikhawulo ngesivinini ngenxa lula. Kodwa kwezinye izimo, ngeke benze ngaphandle kwalo.

Ngakho akufanele silindele nomthelela emakethe yi eSATA esibonakalayo, kodwa ngokushesha ngeke nginikeze ezikhundleni zawo, ngoba isidingo ke isasekhona.

Ochwepheshe abaningi baye bame kwelokuthi lokhu okujwayelekile kuyoba khona kuze ukusabalala indinganiso entsha yesimanje, noma ngokuhamba kwesikhathi, namanje ukuthatha igunya USB 3.0. Nokho, kwaze kwaba lokho kwenzeka, sikwazi ukuthenga ngokuphepha futhi ezitolo, letisebenta ngesisekelo eSATA.
