• SATA uye eSATA anoshanda zvakasiyana chiratidzo mumatunhu;
• kuronga eSATA dzimwe nguva zvinoda chaiyo controller pamusoro hurongwa bhodhi;
• asi asunungurwa havasi mano akawanda kutsigira pomureza uyu.

Kana mashoko kutapurirana kumhanya, asi eSATA ari mukuru munhau iyi zvino kumbonyanya kwakapararira USB 2.0, zvibereko asi yazvino USB 3.0. Zvinogoneka kuti izvi kwakabatana uye kuti nhasi, eSATA connectors havasi dzakakurumbira: pashure zvose, munhu USB kushanda nyore uye nokukurumidza shanduro 3.0 pamusoro.

mhando eSATA

Oddly zvakakwana, asi inowanikwa ine yayo mhuka. Zvisinei, havasi zvikuru. Kana pane, chete maviri:

1. Chaizvoizvo eSATA, uye pamusoro yekunwa zvinhu.
2. ESATAp - a pachena kuchiitwa ichi mhando chengarava yava zvichibvira kuita zvokudya mano zvakananga Via ane eSATA waya, SATA zvakare vakakumbira fanira simba wedzerai Via ane kwokunze kunobva. Postfix peji isimba - simba.

Zvaizoratidza sokuti pamwe veMubatanidzwa zvakadai mwero sezvo eSATAp, zvose matambudziko vakanga ragadziriswa, uye chiteshi akagadzirira vagone kuzvishandira. Asi zvino, ndakasvika USB 3.0, uye eSATAp vakasagona kukwikwidzana naye.

Uye ndinoiitawo 12 volts

Zvisinei, batanidza chero USB mudziyo zvaunogona uye eSATA chiteshi. Interfaces kubvumira ichi. Saka mawa maumbirwe mudziyo kuchaitika uye kuti mashoko kupararira mune mativi.

Asi dambudziko huru hazvisi kuti vamwe nemotokari mienzaniso yakaoma zvinoda kwete chete mureza 5 volts zvokudya, asi vakawanda 12. asi haina inopiwa nokuti Laptops akadaro simba simba zvitengeswa. Uye hwakavandudzwa shanduro yakazokudziridzwa nekuti eSATAp, iyo inopa kuvapo zvimwe simba nevanhu vari connector. Inowanikwa vaakagamuchira kurongwa zita eSATAdp, kureva Dual simba.

Kana pasina eSATA

Kwete kazhinji, asi dzimwe nguva ndizvo zvakafanira kuuya eSATA-chete mudziyo pamberi SATA-chiteshi chengarava riri motherboard. Somuenzaniso, kana uchida kubatanidza ane zvimwewo eSATA upi mudziyo.

Izvi zvinogona kuitwa, asi achatora kungotarisa chiwedzerwa wire unobatanidza zvakananga SATA pamusoro motherboard. Kana tiri kutaura pamusoro Laptop kana netbook, mugumisiro kubatana kwakadaro kunobvira nomukombiyuta adapteri PC Card, uyewo kuburikidza Express Card. Asi ichi zvazvingava, kunonyanyisa waya pakureba achatungamirira chete meter, izvo zvisiri nyore nguva dzose.

External Namano eSATA,

Pane imwe nguva, kusati kwatombova USB 3.0, eSATA inowanikwa iri yakasimba zvakakwana ramangwana rakajeka. ESATA kwokunze ngarurege inogona kuwanika pasero ikozvino. Pashure pezvose, USB 3.0 harisati vakakwanisa ndokudzinga padzimba dzaro USB 2.0 mugadzi.

Uye nokuti eSATA mureza rinotarisirwa zvikurukuru nokuda nokukurumidza date Exchange, zviri zvikuru musoro kuti mugove nechitarisiko namano kuti kutsigira inowanikwa ichi cheshumba, kuti marudzi ose Zvifambiso. Iri kwokunze Zvifambiso zvakaoma uye nokupenya Zvifambiso. Asi unogona kuwanikwa kutengeswa sezvo vaidhinda uye scanners, izvo zvinoshandiswa kwakadai maererano.

Sezvineiwo, vamwe kuvhiringidzika chokuita kuvapo kunyange chiduku, asi kusiyana pakati SATA inowanikwa, ane eSATA, eSATAp, uye eSATAdp, kwakaita kuti chokwadi kuti vatengi vari kuvhiringidzika pamusoro kugarisana pamusoro zviteshi uye netambo. Uye kunyange eSATA adapteri Hazviwanzovi kubatsira kupedza dambudziko iri, kunyanya kana zvinetso hahuenderani chete, asiwo tinofanira kuitisa mamwe kudya (zvakafanana 12 volts). Kunze eSATAdp mureza asati kwezvipimo.

Nepo chete vanofanira kunyatsotevera kuongorora kugarisana pakati netambo kuitira kuti kuvhiringidza eSATA waya, SATA nevamwe. Uye tariro kana vose pakupedzisira fananidza kana kutsiva SATA zvengarava kusiyana kunouya vamwe zvakawanda zvakasikwa chiteshi.

Wadii kuva FireWire kana USB

Chokwadi, mhinduro yomubvunzo wokuti kana, eSATA - chii, haagoni kunzi kwakakwana pasina kuedza kuongorora mikana kubva vakwikwidzi. Kana ichi - FireWire uye USB.

Uye zvikonzero kuti eSATA achiri asina kuribvisa navo, vari vatatu:

1. Kuchinjana mashoko Via izvi zviviri zvengarava, protocols vanofanira kutendeuka Akash kana SATA kuti USB kana chete FireWire. Zvisinei, kuti bandwidth ane zvinokosha painogumira. Zvakanga zvakawanda munguva yakapfuura, asi pamwe veMubatanidzwa hwakasimba-mamiriro nemotokari inokwana 500 GB, izvo nhasi hapana kushamisika, pachikumbaridzo ichi yava kunyatsooneka.
2. Chikonzero chechipiri iri chokuti kunyange zvakadaro pane kukamurwa pamusoro FireWire date yedzimudzangara zvazvingava - Mbps 400 sezvo FireWire controllers ushande mureza IEEE 1394A. Pano, mumwe mutemo kwakadaro achirova hakusi zvokuti kana ukashandisa huru zvakaoma nemotokari, sei zvikuru nokukurumidza uye bhuku nokuda bvuta-arrays, izvo, chokwadi, kunotora chaizvo aimhanya.
3. Pakupedzisira, Zvifambiso FireWire uye USB kunobva havana kuwana zvimwe pasi. Somuenzaniso, Smart mashandiro Panguva iyoyowo, eSATA akachengetedza kubva drawback ichi.

Kunyange yemakwikwi interfaces pamatunhu kudiwa nokuda chinzvimbo uye faira nhengo dzayo nyore, asi mune zvimwe zviitiko haagoni kuita pasina eSATA-inowanikwa. Somuenzaniso, kana inodzidzisa kunoda kumhanya kupararira hombe Vhoriyamu mashoko, mureza ichava yakanaka huchapedza matambudziko akadaro. Zvinosuruvarisa kwayo Implementation kunosanganisira zvimwe zvinetso zvekushandisa, asi kuvapo mamwe simba, semuenzaniso, nevanhu zvokunze Unit, hachizovi kuva dambudziko.

kutarisira eSATA

Kunyange zvakaoma kutaura pamwe Mhedziso vimbiso maererano remangwana inowanikwa ichi. Asi pasina kuedza achatanda pakupindura mubvunzo wokuti, eSATA - chii, uye haagoni kuita.

Kunyange zvazvo pane akaipa ari pamusika kuti vatsigire basa pamwe zvengarava akadai USB 2.0, USB 3.0, uyewo pamusorosoro FireWire, eSATA ramangwana isingagari. Kudivi rimwe, vagadziri havasi kuenda vanoshingaira kushandisa chengarava ichi mune zvose mano ayo, uye pane dzimwe - achiri akaita Zvifambiso pamwe inowanikwa ichi, asiwo pamusoro USB 3.0 inokanganikwa.

ESATA anotarisa zvakanaka, kana waida Somuenzaniso, maererano nokuda hombe okuchengetera kana kubudiswa Multimedia tigutsikane ari HD. Uyewo, inowanikwa iri richabatsira wose kuva musha wako bvuta-kuko.

Asi vanozvishandisa vazhinji vanosarudza kushandisa kwavo zuva basa uye nomumugwagwa kwaitora nguva, asi izvozvo zviri nyore uye nzwisisa inowanikwa sezvo USB 2.0. Pashure pezvose, vakawanda vavo vasingadi kushandira pamwe kutsanya uye capacious amatura mano, mukuwedzera, vanoshandisa kazhinji deters kudiwa mamwe powering mudziyo pamwe eSATA-inowanikwa. Vachida kuisa nevamwe yemararamiro pakukurumidza nokuda zvimunakire. Asi mune zvimwe zviitiko, hachigoni kuita pasina izvozvo.

Saka haufaniri kuramba kutarisira kuchikosha kukanganisa kutengeswa pedyo eSATA inowanikwa, asi nokukurumidza hahuzongoparari mumaoko zvinzvimbo zvavo, nekuti kudiwa riripo achiri.

Nyanzvi dzakawanda nharo mureza uyu ruchavapo kusvikira pakuparadzirwa itsva vomureza ano, kana pamusoro kwenguva, achiri kutora kuvamumwe USB 3.0. Zvisinei, kusvikira izvozvo zvaitika, tinogona zvakachengeteka kutenga uye zvitoro, izvo anoshanda maererano eSATA.
