ESATA - yog dab tsi? Hom thiab eSATA

Niaj hnub no eSATA chaw nres nkoj tau ntev ceased mus yuav ib yam dab tsi tiag tiag tshiab thiab txawv. Txawm li cas los, tsis yog txhua txhua cov neeg siv yeej paub txog nws thiab tsis kom meej meej xav txog tej yam dab tsi zoo thiab tsis zoo ntawm cov txuj no qhia nyob rau hauv lub hnub ua hauj lwm nrog koj lub computer.

Ib me ntsis txog eSATA

Ntawm cov hoob kawm, beginners yuav tshwj xeeb tshaj yog xav paub, eSATA - dab tsi nws yog dab tsi thiab nws noj thiab haus. Yog hais tias koj sim los teb cov lus yooj yooj yim, cov txuj no serial chaw nres nkoj lus dag nyob rau hauv ceev thiab yooj yim ntawm kev siv qhov chaw ntawm cov tsoos thiab lub USB2.0 txheem SATA. Lub sij hawm decryption yog ib qho abbreviated Sab nraud Serial ATA, i.e. chaw nres nkoj, thov advanced technology serial cov ntaub ntawv sib txuas lus thiab muaj lub peev xwm "kub" hloov rau ntawm cov yoov raws li ib tug nyuaj tsav, thiab lwm yam pab kiag li lawm uas txuas mus rau lub computer.

Txawm tias muaj tseeb hais tias eSATA-kev twb kev txuas tuaj nyob rau hauv 2004, niaj hnub no, cov neeg siv feem ntau xav tau ib tug ntau tsoos technologies - USB thiab SATA.

meej mom

Ntawm cov hoob kawm, eSATA txheem yuav tsis tau kis, tsis yog nws muaj nws lub hom phiaj zoo. Thiab no muaj xws li:

• tau txuas rau lub cable mus rau kis cov ntaub ntawv mus rau 2 m tsis muaj kev pheej hmoo ntawm distortion;
• eSATA teeb liab tau tshaj SATA;
• Sai ntaub ntawv hloov lwm lub tsev piv nrog USB2.0;
• pheej yig nyob rau hauv ntau lawm tso cai rau kom equip nrog ntau chipsets thiab eSATA ports siv no jack nyob rau hauv ntau pab kiag li lawm. Piv txwv li, yog eSATA lwm hard drive thiab txawm ib tug flash card;
• nyuaj drives nyob rau tib lub sij hawm yuav ua ke nyob rau hauv ib tug RAID-arrays;
• yuav nqa tawm los hloov lub hard drive rau tus yoov, uas yog tsis yooj yim sua yog muab cov kev siv ntawm ib tug ib txwm SATA-interface.

Raws li koj tau pom, cov kev pab cuam los ntawm qhov no interface abound, txawm nyob rau hauv kev sib piv nrog rau tej ntau thiab paub cov qauv xws li USB2.0 thiab SATA.

shortcomings

Teb rau ib lo lus nug, eSATA - dab tsi nws yog, peb yuav tsis quav ntsej cov shortcomings ntawm no hom ntawm kev twb kev txuas. Txawm tias muaj tseeb hais tias qhov no hom ntawm interface muab tso rau hauv lub lag luam txij li thaum 2004, tsis yog txhua txhua pab kiag li lawm yog nruab nrog rau tus txheej txheem ports, thiab tsis tau nws siv yog nyuab los ntawm ib co inconveniences:

• Lub cev incompatibility SATA thiab eSATA ports;
• baud tus nqi yog tseem me ntsis qis dua hais tias ntawm SATA. Heev heev hluavtaws kev ntsuam xyuas tau paub tseeb hais tias qhov no;
• cable ntev yog tas rau ob meters, uas yog tsawg tshaj li nyob rau hauv cov ntaub ntawv ntawm USB;
• eSATA HDD yuav tsum tau ntxiv hwj chim ntawm USB thiab 1394, los yog los ntawm ib tug pa hluav taws xob (nyob rau hauv lub tshiab qauv ntawm sab nraud pab kiag li lawm qhov yuav tsum tau feem ntau disappears);
• SATA thiab eSATA thov sib txawv teeb liab ntau;
• miv eSATA tej zaum yuav tsum tau ib tug tshwj xeeb xws li nyob rau hauv lub system board;
• tsis tau tso tawm yog tsis muaj ntau pab kiag li lawm uas txhawb cov txuj no.

Raws li rau lub cov ntaub ntawv hloov lwm lub tsev ceev, lub eSATA yog superior rau hauv no hwm tau tam sim no haum ntau USB 2.0, tawm los tab sis cov niaj hnub USB 3.0. Nws yog tau hais tias qhov no yog kev cob cog rua thiab lub fact tias niaj hnub no, eSATA connectors yog tsis nrov: tom qab tag nrho, ib tug USB mus ua hauj lwm yooj yim dua thiab ceev version 3.0 saum toj no.

hom eSATA

Oddly txaus, tab sis lub interface nws muaj nws tus kheej lub hom. Txawm li cas los, lawv yog tsis yog li ntawd ntau npaum li cas. Los yog es, tsuas yog ob tug:

1. Ua tau eSATA, thiab hais txog tej uas cov saum toj no hais nta.
2. ESATAp - ib tug txawv feature ntawm no hom ntawm qhov chaw nres nkoj uas tau ua tau mus nqa tawm pub pab kiag li lawm ncaj qha ntawm ib tug eSATA cable, SATA kuj demanded ib tug yuav tsum hwj chim mov ntawm ib tug sab nraud qhov chaw. Postfix p yog fais fab tuag - lub hwj chim.

Nws yuav zoo li uas nrog lub advent ntawm xws li ib tug txheej txheem raws li eSATAp, tag nrho cov teeb meem twb daws, thiab qhov chaw nres nkoj yog npaj txhij los ua nws tus kheej-txaus. Tab sis, ces kuv tuaj txog, USB 3.0, thiab eSATAp yuav tsis lwv nrog nws.

Thiab ntxiv rau 12 volts

Txawm li cas los, txuas tej USB ntaus ntawv koj ua tau thiab mus rau lub eSATA chaw nres nkoj. Interfaces pub no. Yog li simultaneous pleev ntaus ntawv yuav tshwm sim thiab cov ntaub ntawv kis tau tus mob nyob rau hauv ob hnub.

Tab sis lub ntsiab teeb meem nyob rau hauv cov ntaub ntawv no yog hais tias ib co nyuaj tsav qauv yuav tsum tau tsis tsuas yog tus txheem 5 volts rau noj, tab sis raws li muaj ntau yam raws li 12. Tab sis nws tsis yog muab rau nyob rau hauv laptops xws li ib tug haib fais fab mov. Thiab ib tug zoo version yog tsim vim hais tias eSATAp, uas muab rau lub xub ntiag ntawm ntxiv hwj chim hu nyob rau hauv lub connector. Lub interface tau txais kev lub npe eSATAdp, piv txwv li dual lub hwj chim.

Yog hais tias muaj yog tsis muaj eSATA

Tsis dhau lawm feem ntau, tiam sis tej zaum nws yog tsim nyog los coj eSATA-tsuas ntaus ntawv nyob rau hauv lub xub ntiag ntawm SATA-chaw nres nkoj nyob hauv lub motherboard. Piv txwv li, yog tias koj yuav tsum tau txuas ib lwm eSATA rau kev ntaus ntawv.

Qhov no yuav ua tau, tab sis nws yuav siv sij hawm ib tug passive extension cable uas txuas ncaj qha mus rau lub SATA rau lub motherboard. Yog hais tias peb yuav sib tham hais txog ib tug laptop los yog ib tug netbook, cov nyhuv xws kev twb kev txuas yog tau ntawm lub adapter PC Card, raws li zoo raws li los ntawm cov Express Card. Tab sis nyob rau hauv cov ntaub ntawv no, lub siab tshaj plaws cable ntev yuav yog tas rau kuv ib 'meter', uas yog tsis ib txwm yooj yim.

Sab nraud pab kiag li lawm nrog eSATA,

Nyob rau ntawm ib lub sij hawm, ua ntej lub advent ntawm USB 3.0, eSATA interface yog check txaus ci yav tom ntej. ESATA lwm tsav yuav tsum muaj nyob rau muag tam sim no. Tom qab tag nrho, USB 3.0 tseem tsis tau muaj kev tswj kom oust thoob plaws nws USB 2.0 predecessor.

Thiab vim hais tias cov eSATA txuj no yog npaj feem rau sai ntaub ntawv pauv, nws yog heev zajlus kom tias tus tsov ntxhuav feem ntawm sab nraud pab kiag li lawm uas txhawb qhov kev interface, ua kom tag nrho cov hom ntawm cov drives. Qhov no lwm nyuaj drives thiab flash drives. Tab sis yuav tsum muaj nyob rau muag li printers thiab scanners, uas yog siv nyob rau hauv no hom ntawm kev twb kev txuas.

Tu siab, tej feeb tsis meej txuam nrog lub xub ntiag ntawm txawm ib tug me me, tab sis muaj ntau haiv neeg ntawm cov SATA interface, ib qho eSATA, eSATAp, thiab eSATAdp, coj mus rau qhov tseeb hais tias tau txais kev pab yog tsis meej pem txog lub compatibility ntawm ports thiab cables. Thiab txawm eSATA adapter tsis yeej ib txwm pab kom daws tau qhov teeb meem, tshwj xeeb tshaj yog yog hais tias tus teeb meem yog tsis tsuas tau tshaj, tab sis kuj yuav tsum tau mus ua ntxiv pub (tib yam 12 volts). Dhau li eSATAdp txheem tseem tsis tau qauv.

Thaum tsuas yuav tau soj ntsuam tus compatibility ntawm lub cables thiaj li tsis mus confuse lub eSATA cable, SATA thiab lwm tus neeg. Thiab cia siab hais tias yog txhua leej txhua tus yog thaum kawg standardize los yog hloov lub SATA ports muaj ntau haiv neeg los ib co ntau universal chaw nres nkoj.

Yog vim li cas tsis muaj ib tug FireWire los yog USB

Ntawm cov hoob kawm, cov lus teb rau lo lus nug ntawm seb, eSATA - dab tsi nws yog, tsis tau yuav tau ua kom tiav tsis muaj ib qho los rau kev tsom xam lub sij hawm los ntawm cov neeg sib tw. Nyob rau hauv cov ntaub ntawv no - FireWire thiab USB.

Thiab yog vim li cas hais tias eSATA yog tseem tsis supplanted los ntawm lawv, yog peb:

1. Yuav kom pauv cov ntaub ntawv ntawm cov ob ports, twg yuav tsum tau hloov patÄ los yog SATA rau USB los yog tib FireWire. Txawm li cas los, lub bandwidth muaj teeb meem loj cov kev txwv. Nws tsis yog ib yam nkaus thiab ntau npaum li cas nyob rau hauv lub dhau los lawm, tab sis nrog lub advent ntawm cov khoom-xeev tsav peev xwm ntawm 500 GB, uas niaj hnub no tsis muaj leej twg yuav tau ras, qhov no pib tau ua heev hnov li cas.
2. Qhov thib ob yog vim li cas cov lus dag nyob rau hauv lub fact tias txawm nyob rau hauv rooj plaub yog ib tug txwv rau FireWire cov ntaub ntawv kis tau tus mob npaum li cas - 400 Mbps li FireWire controllers hauj lwm rau tus qauv IEEE 1394A. Ntawm no, xws li ib tug txwv yog ciav tsis yog li ntawd ntau npaum li cas thaum koj siv ib tug loj hard drive, ntau npaum li cas ceev thiab ntim rau RAID-arrays, uas yog, ntawm chav kawm, yuav tsum tau heev loj speeds.
3. Thaum kawg, lub drives FireWire thiab USB raws li tsis muaj kev nkag tau rau tej nta tsawg. Piv txwv li, SMART muaj nuj nqi Nyob rau tib lub sij hawm, eSATA spared los ntawm no drawback.

Txawm tias kev sib tw interfaces nyob rau hauv siab thov vim cov nyob qib thiab cov ntaub ntawv cov neeg ntawm nws kom yooj yim, tab sis nyob rau hauv tej rooj plaub tsis tau tsis muaj eSATA-interface. Piv txwv li, yog hais tias tus neeg siv yuav tsum tau ib tug kev kub ceev kis tau tus mob ntawm ib tug loj ntim ntawm cov ntaub ntawv, tus qauv yuav ua tau ib tug zoo tshaj plaws rau tej teeb meem. Tu siab, nws siv yuav tej yam kev teeb meem, tab sis muaj cov ntxiv hwj chim, e.g., los ntawm ib tug sab nraud tsev, nws yuav tsis muaj teeb meem.
