ESATA - waa maxay? Noocyada iyo eSATA

Maanta dekedda eSATA ayaa muddo dheer iska daayeen inay noqon wax run ahaantii cusub oo qalaad. Si kastaba ha ahaatee, ma dhammaan dadka isticmaala aqoon u leh oo aan si cad qiyaasi waxa faa'iidada iyo khasaaraha ee caadiga ah tani waxay bixisaa in hawl maalmeedka la computer ah.

A yar oo ku saabsan eSATA

Dabcan, bilowga ah waxay noqon doontaa gaar ahaan xiiso in la ogaado, eSATA - waxa uu yahay iyo waxa la cunaa. Haddii aad isku daydo in aad ka jawaabto fudud, tan caadiga ah dekedda serial been in xawaaraha iyo fududaato in la isticmaalo meel u dhaxaysa dhaqanka iyo heerka USB2.0 ku Sata. decryption dheer waa soo gaabiyey Dibadda ALMAATA Serial, i.e. dekedda, codsanaya technology advanced isgaarsiinta xogta serial iyo karti "kulul" bedelka on Daqsi sida drive adag, iyo qalabka kale ee ku lifaaqan kombiyuutarka.

In kasta oo xaqiiqda ah in eSATA-xiriir u yimid sanadkii 2004, maanta, dadka isticmaala inta badan waxay door bidaan ah farsamooyinka dheeraad ah dhaqanka - USB iyo Sata.

sharafta

Dabcan, Heerka eSATA aan doonaynin in aad sii faafin, oo aan in uu leeyahay faa'iidooyin Ujeedada. Oo waxaa ka mid ah:

• suurtagalnimada of kordhin cable in ay gudbiyaan xogta ilaa 2 m oo aan halista ah ee dhalanrog,
• signal eSATA socon Sata,
• De-wareejinta xogta la USB2.0 marka la barbar dhigo;
• cheap in wax soo saarka u ogolaanaya in ay xooji chipsets badan iyo dekedaha eSATA in ay isticmaalaan Jack this ee hindisooyin badan. Tusaale ahaan, waxaa jira eSATA drive adag dibadda iyo xitaa kaarka flash a;
• drives adag waqti isku mid ah la isku dari karaa in a weerar-Arrays,
• la fulin karo si uu u bedelo drive adag on Daqsi, waa wax aan macquul aheyn haddii la siiyo isticmaalka dhaqameed Sata-interface.

Sida aad arki karto, faa'iidooyinka ka interface this noogu badan, xitaa marka la barbardhigo heerka baahsan oo caan ah sida sida USB2.0 iyo Sata.

ceebaha

Ka jawaabaya su'aal, eSATA - waxa ay tahay, ma iska indho tiri karo ayaa haddana ceebaha noocan ah ee la xidhiidha. In kasta oo xaqiiqda ah in noocan ah interface rido hawlgalka tan iyo 2004, dhammaan qalabka aan qalabaysan dekedaha caadiga ah, oo haddana ay la isticmaalo waa mid adag oo ay ku haboonayn qaar ka mid ah:

• incompatibility Physical dekedaha Sata oo eSATA;
• Heerka Baud weli waa wax yar ka hooseeya in Sata. imtixaanada dardaro fara badan ayaa xaqiijisay in this;
• dhererka cable ku eg tahay ilaa laba mitir, taas oo ah wax ka yar in ay dhacdo USB,
• eSATA HDD u baahan tahay awood dheeraad ah via USB iyo 1394, ama iyada oo loo marayo outlet a caadiga ah (ee ku dayashada cusub ee qalabka dibadda baahida loo qabo in inta badan baaba'aa);
• Sata oo eSATA codsan heer signal kala duwan;
• in uu abaabulo eSATA mararka qaarkood waxay u baahan tahay xakamaysada gaar ah on board nidaamka;
• weli sii daayay aan ku jira hindisooyin badan oo taageera Heerka this.

Sida ee xawaaraha kala iibsiga data, eSATA waa ka xoogbadan, saaraysa ayaa haatan USB si caddaalad ah baahsan 2.0, dhalidda laakiin USB casriga ah 3.0. Waxaa suurto gal ah in ay taasi ku xiran yahay iyo xaqiiqda ah in maanta, Xidhiidhiyayaasha eSATA ma aha oo caan ah, ka dib oo dhan, USB ah in ay ka shaqeeyaan fudud iyo version xawaaraha 3.0 kor ku xusan.

noocyada eSATA

Qaab daran oo ku filan, laakiin interface leeyahay noocyada ay u gaar ah. Si kastaba ha ahaatee, ma ay joogin aad u badan. Ama halkii, laba keliya:

1. Dhab ahaantii eSATA, oo ku saabsan sifooyinka kor ku xusan.
2. ESATAp - feature a kala duwan ee noocan ah ee dekedda in uu noqday suurtagal ah si ay u fuliyaan qalab si toos ah quudinta via cable eSATA ah, Sata ayaa sidoo kale dalbaday in sahayda awood khasab via il dibedda ah. Postfix p waa awood - xoogga.

Waxaa u muuqan lahaa in la dhalashada ee caadiga ah sida eSATAp sida, dhibaatooyinka oo dhan la xalliyo, iyo dekedda ayaa diyaar u ah inay noqdaan dad isku filan. Laakiin markaas waxaan u yimid, USB 3.0, iyo eSATAp la tartami kari isaga la.

Oo lagu daray 12 volts

Si kastaba ha ahaatee, xirmaan qalab kasta oo USB aad awoodo iyo dekedda eSATA ah. Interfaces this ogolaan. Sayidka qalab qurxiyo isku mar dhici doonto iyo gudbinta xogta ee labada dhinac.

Laakiin dhibaatada ugu weyn ee ay dhacdo in this waa in qaar ka mid ah lagu daydo drive adag u baahan tahay oo keliya ma aha caadiga ah 5 volts si ay u quudiyaan, laakiin sida ugu badan 12. Laakiin waxa aan la siiyaa in laptops sida saad xoog awood badan. Oo version ah hagaagtay loo sameeyay maxaa yeelay eSATAp, kaas oo bixiya for joogitaanka xiriirada awood dheeraad ah oo isku xira ee. interface ayaa helay rasmi magaca eSATAdp, sida dual awood.

Haddii ay jirto eSATA no

Ma aha inta badan, laakiin mararka qaar waxaa lagama maarmaan ah in la keeno qalab eSATA-kaliya ee ay joogaan of Sata-dekedda on motherboard ah. Tusaale ahaan, haddii aad u baahan tahay in ay ku xidhmaan eSATA dibadda si ay u qalab kasta.

Taas waxaa la samayn karaa, laakiin waxay qaadan doontaa cable a dadban kordhinta in si toos ah isku xira in Sata ku motherboard ah. Haddii aynu ka hadlayno laptop ama netbook ah, la xidhiidha saamaynta sida ay suurto gal ah via Card PC adabtarada ah, iyo sidoo kale iyada oo loo marayo Card Express. Laakiin kiiskan, oo dhererkiisu wuxuu cable ugu badnaan la xadidaa, waxaana kaliya hal mitir, taas oo aan had iyo jeer ku haboon.

qalabka External la eSATA,

Ugu hal mar, ka hor dhalashada of USB 3.0, eSATA interface waa raagaya ku filan mustaqbalka dhalaalaya. ESATA drive dibadda waxaa laga heli karaa on sale hadda. Ka dib oo dhan, USB 3.0 uusan weli u suurtagashay in ay taqaluseyso oo dhan ay USB 2.0 horreeyay.

Oo maxaa yeelay Heerka eSATA waxaa loogu tala galay ee is-dhaafsiga xogta degdeg ah, waa arrin macquul ah in qayb libaax ee qalabka dibadda in ay taageeraan interface this, ka dhigi cayn kasta oo drives. Tani dibadda drives adag iyo drives flash. Laakiin waxaa laga heli karaa for sale sida madbacadaha iyo scanners, kuwaasi oo loo isticmaalo in noocan ah ee la xidhiidha.

Nasiib darro, qaar ka mid wareer la xidhiidha joogitaanka xataa yar, laakiin kala duwanaanta ku dhex interface Sata, an eSATA, eSATAp, iyo eSATAdp, keentay in xaqiiqda ah in macaamiisha waa jahwareer ku saabsan waafaqid ee dekedaha iyo fiilooyinka. Oo xataa eSATA adabtarada aysan mar walba ku caawiyaan si ay u xaliyaan dhibaatada this, gaar ahaan haddii dhibaato ah ma aha oo kaliya la jaan qaada, laakiin sidoo kale baahida loo qabo in si ay u qabtaan quudinta dheeraadka ah (isku mid ah 12 volts). Ka sokow Heerka eSATAdp aan weli la cabiran.

Iyadoo u baahan tahay oo kaliya in ay si dhow ula socdaan waafaqid ee fiilooyinka si aanay u khaldaan cable eSATA ah, Sata iyo kuwa kale. Oo rajeynayaa in labada qof walba waxa uu ugu dambeyntii jaangooyo ama bedeli dekedaha Sata kala duwanaanshaha yimaado qaar ka mid ah dekedda more universal.

Waa maxay sababta aan lahayn FireWire ama USB

Dabcan, jawaabta su'aashan ah in, eSATA - waxa uu yahay, ma la oran karo waa dhamaystiran oo aan isku day si ay u falanqeeyaan fursado ka tartamaya. Xaaladdan oo kale - FireWire iyo USB.

Iyo sababaha ay eSATA weli ma khiyaaneeyey iyaga by, waa saddex:

1. In ay is dhaafsadaan xogta via labadan dekedaha, hab maamuuska u baahan yihiin in loogu badalo PATA ama Sata in USB ama FireWire isku. Si kastaba ha ahaatee, ka bandwidth uu leeyahay la dhaafi karin oo muhiim ah. Waxa aan ahaa aad u badan ee la soo dhaafay, laakiin dhalashada awoodda drive adag-state of 500 GB, taas oo maanta cidna la yaabi doonaa, marinka this waxa uu noqday arrin la dareemi karo.
2. Sababta labaad been in xaqiiqda ah in xitaa haddii ay dhacdo waxaa jira xad ah oo ku saabsan heerka gudbinta xogta FireWire - 400 Mbps sida ilaaliyaal FireWire shaqeeyaan on caadiga ah IEEE 1394A. Halkan, xadaynta noocan oo kale ah taabta ma aha sidaas u badan marka aad isticmaasho drive badan oo adag, immisa xawaaraha iyo mugga for weerar-Arrays, kuwaas oo ah, dabcan, waxay u baahan yihiin xawaare aad u badan.
3. Ugu dambeyntii, FireWire ku drives iyo USB ku salaysan ma ay helaan qaababka qaarkood hooseeyo. Tusaale ahaan, function SMART Isla mar ahaantaana, eSATA tudhay ka khasaare this.

Inkastoo interfaces tartan ee baahida weyn ee ay sabab u tahay darajo iyo xubnaha file ay sahlanaato, laakiin mararka qaarkood ma aan samayn karo aan eSATA-interface. Tusaale ahaan, haddii user u baahan gudbinta a xawaaraha sare ee mugga weyn ee macluumaadka, heerka uu noqon doono xal fiican ee dhibaatooyinka sida. Nasiib darro, hirgelintiisana ay ku lug leedahay dhibaatooyin farsamo gaar ah, laakiin joogitaanka awood dheeraad ah, tus, by unit dibadda, ma noqon doonto dhibaato.

rajada eSATA

Inkastoo ay adag tahay in la yidhaahdo wax Yaqiinsanayn buuxda oo ku saabsan mustaqbalka interface this. Laakiin aan isku dayaya in ay Saadaasha markii jawaabay su'aasha ah haddii, eSATA - waxa uu yahay, iyo ma aan samayn karo.

Inkasta oo ay jiraan qalabka suuqa in lagu taageero shaqada la dekedaha sida USB 2.0, USB 3.0, iyo sidoo kale kor FireWire ah, eSATA mustaqbalka aan la hubin. Dhinaca mid, saarayaasha ma aha in si dhaqso ah ay si firfircoon uga isticmaalaan dekedda this in dhammaan qalabka ay, oo dhinaca kale ah - weli ka dhigay drives la interface this, laakiin sidoo kale ku saabsan USB 3.0 lagama illaawin.

ESATA muuqataa wanaagsan, haddii loo baahdo, tusaale ahaan, la xidhiidha kaydinta bulk ama processing of content multimedia in HD ah. Sidoo kale, interface this qof walba ku caawin doona in ay guri aad weerar-soo diyaariyeen.

Laakiin dadka isticmaala badan door bidaan in ay isticmaalaan in shaqo-maalmeedka iyo, laakiin sida interface a gaabis fudud oo dareen leh sida USB 2.0. Ka dib oo dhan, badankooduse wax ma u baahan tahay in la aaladaha kaydinta soomi iyo capacious shaqeeyaan, marka lagu daro, dadka isticmaala inta badan lagu daciifiyay baahida loo qabo qalab ay beeluhu dheeraad ah la eSATA-interface. Waxay diyaar u saaray la xadad qaar ka mid ah xawaaraha aawadood sahlanaato yihiin. Laakiin mararka qaarkood, ma uu samayn karo iyada oo aan.

Sidaas daraaddeed waa in aad sii wadaan inay filayaan saamayn wayn ku yeelan suuqa by interface eSATA ah, laakiin si dhakhso ah u ma gelin doonaa gacantaada, ay, sababtoo ah weli loo baahan yahay, waxaa ka jirta.

Aqoonyahano badan ayaa ku doodaya in heerka this jira doonaa ilaa faafidda heer cusub oo casri ah, ama in ka badan waqtiga, weli qaadan eegidda USB 3.0. Si kastaba ha ahaatee, ilaa ay taasi dhacdo, waxaan si ammaan ah ka iibsan kartaa dukaamada, kuwaas oo ku shaqayn ku salaysan eSATA.
