USB 3.0 yog Universal Serial Bus (USB) tus qauv, tso tawm thaum lub Kaum Ib Hlis 2008. Feem ntau cov khoos phis tawj tshiab thiab cov cuab yeej tsim tawm niaj hnub no txhawb tus qauv no, uas feem ntau hu ua SuperSpeed USB.
Cov khoom siv uas ua raws li tus qauv USB no tuaj yeem xa cov ntaub ntawv ntawm qhov siab tshaj plaws ntawm 5 Gbps (5, 120 Mbps), tab sis qhov tshwj xeeb suav tias yog 3, 200 Mbps tsim nyog hauv kev siv txhua hnub. Qhov no yog qhov tsis sib xws rau cov qauv USB yav dhau los xws li USB 2.0 uas, qhov zoo tshaj plaws, tuaj yeem hloov ntawm 480 Mbps, lossis USB 1.1 uas tawm ntawm 12 Mbps.
USB 3.2 yog qhov hloov kho tshiab ntawm USB 3.1 (SuperSpeed+), txawm tias USB4 yog tus qauv tshiab. USB 3.2 nce qhov theoretical siab tshaj qhov ceev mus rau 20 Gbps (20, 480 Mbps), thaum USB 3.1 los ntawm qhov siab tshaj plaws ntawm 10 Gbps (10, 240 Mbps).
Cov khoom siv qub USB, cables, thiab adapters tuaj yeem sib haum nrog USB 3.0 kho vajtse, tab sis yog tias koj xav tau cov ntaub ntawv xa mus ceev tshaj plaws, txhua yam khoom siv yuav tsum txhawb nqa.
USB 3.0, USB 3.1, thiab USB 3.2 yog cov npe "laus" rau cov qauv no. Lawv lub npe hu ua USB 3.2 Gen 1, USB 3.2 Gen 2, thiab USB 3.2 Gen 2x2, feem.
YUSB 3.0 yog dab tsi?
USB 3.0 Connectors
Tus txiv neej txuas ntawm USB 3.0 cable lossis flash drive hu ua lub ntsaws. Poj niam connector ntawm lub computer chaw nres nkoj, extension cable, los yog ntaus ntawv yog hu ua lub receptacle.
- USB Hom-A: Cov khoom txuas no, raug xa mus rau USB 3.0 Standard-A, yog cov duab plaub yooj yim ntawm USB connectors, zoo li lub ntsaws ntawm qhov kawg ntawm lub flash drive. USB 3.0 Hom-A plugs thiab receptacles yog lub cev sib xws nrog cov los ntawm USB 2.0 thiab USB 1.1.
- USB Hom-B: Cov khoom sib txuas no, raug xa mus rau USB 3.0 Standard-B thiab USB 3.0 Powered-B, yog square nrog ib qho loj me me rau saum thiab feem ntau pom ntawm cov tshuab luam ntawv thiab lwm yam khoom siv loj. USB 3.0 Hom-B plugs tsis sib xws nrog Type-B receptacles los ntawm cov qauv qub USB, tab sis cov plugs los ntawm cov qauv qub yog sib xws nrog USB 3.0 Hom-B receptacles.
- USB Micro-A: USB 3.0 Micro-A connectors yog cov duab plaub, "ob feem" ntsaws thiab pom muaj nyob ntawm ntau lub xov tooj smartphones thiab cov khoom siv nqa tau zoo sib xws. USB 3.0 Micro-A plugs tsuas yog siv tau nrog USB 3.0 Micro-AB receptacles, tab sis laus dua USB 2.0 Micro-A plugs yuav ua hauj lwm hauv USB 3.0 Micro-AB receptacles.
- USB Micro-B: USB 3.0 Micro-B connectors zoo ib yam li lawv cov Micro-A counterparts thiab pom nyob rau hauv cov khoom zoo sib xws. USB 3.0 Micro-B plugs tau tshaj USB 3.0 Micro-B receptacles thiab USB 3.0 Micro-AB receptacles nkaus xwb. Cov laus USB 2.0 Micro B plugs kuj muaj lub cev sib xws nrog ob lub USB 3.0 Micro-B thiab USB 3.0 Micro-AB receptacles.
USB 2.0 specification suav nrog USB Mini-A thiab USB Mini-B plugs, nrog rau USB Mini-B thiab USB Mini-AB receptacles, tab sis USB 3.0 tsis txhawb cov connectors. Yog tias koj ntsib cov connectors no, lawv yuav tsum yog USB 2.0 connectors.
Tsis paub meej tias lub cuab yeej, cable, lossis chaw nres nkoj yog USB 3.0? Ib qho kev qhia zoo ntawm kev ua raws cai yog thaum cov yas nyob ib puag ncig lub ntsaws lossis lub thawv ntim khoom yog xim xiav. Thaum nws tsis xav tau, USB 3.0 specification pom zoo kom xim xiav kom paub qhov txawv ntawm cov cables los ntawm cov tsim los rau USB 2.0.
Koj tuaj yeem saib daim ntawv qhia USB lub cev sib raug zoo rau ib nplooj ntawv siv rau dab tsi- haum-nrog- dab tsi.

Thawj Microsoft kev khiav hauj lwm uas suav nrog kev txhawb nqa rau USB tus qauv no yog Windows 8. Lub Linux ntsiav tau txhawb nqa txij li xyoo 2009, pib nrog version 2.6.31. Saib Puas Yog Kuv Lub Computer Txhawb USB 3.0? Yog tias koj nyob ntawm Mac.
Japanese computer peripheral tuam txhab Buffalo Technology yog thawj zaug xa khoom USB 3.0 rau cov neeg siv khoom hauv xyoo 2009.
Tsis muaj qhov ntev tshaj plaws ntawm cable uas txhais los ntawm USB 3.0 qhov tshwj xeeb, tab sis 10 ko taw yog qhov txwv siab feem ntau siv.
Koj tuaj yeem nruab USB 3.0 tsav tsheb hauv Windows yog tias lawv tau ua tsis zoo thiab koj cov khoom siv tsis ua haujlwm zoo lawm.
