nrawm nrawm
USB 3.0 yog qhov kev nce qib loj thaum peb piv nws nrog USB 2.0. Qhov sib txawv loj tshaj plaws nyob rau hauv qhov ceev uas USB 3.0 tuaj yeem sib txuas lus nrog tus tswv tswj hwm uas yog lub khoos phis tawj. Qhov zoo ntawm nws yog tias nws rov qab tau tshaj uas yog nws tuaj yeem siv nrog USB 1.0 thiab USB 2. 0. Thaum USB 2.o muaj qhov siab tshaj plaws ntawm 480 Mbps, uas tau txiav txim siab txaus nyob rau lub sijhawm ntawd, tam sim no nrog kev muaj. pab kiag li lawm uas muaj peev xwm mus txog 64 GB, nws zoo li qeeb heev. Cov ntaub ntawv hloov tsheb los ntawm cov khoom siv uas muaj peev xwm loj tuaj yeem siv sijhawm ntau teev nrog USB 2. 0. Kev taw qhia ntawm USB 3.0 tau hloov pauv cov ntaub ntawv hloov pauv ntawm cov khoom siv thiab khoos phis tawj nrog qhov siab tshaj plaws hloov pauv ceev ntawm 4.8 Gbps uas yog kev txhim kho loj dua li kev nrawm dhau los. Qhov no yog 10 npaug ntawm qhov nrawm uas tuaj yeem ua tiav nrog USB 2.0
Nyob zoo
Hais txog kev siv hluav taws xob thiab kev xav tau, USB 3.0 yog qhov ntsuab ntau dua piv rau USB 2.0. USB 3.0 cov khoom siv muab lub zog ntau dua rau cov khoom siv thiab txuag hluav taws xob thaum lub cuab yeej tsis ua haujlwm lossis tau them.
Tus nqi hloov pauv zoo dua nrog USB 3.0 tso cai rau cov khoom siv nrog cov bandwidth siab xws li Hi txhais video streaming tau. Cov tshuab kaw suab digital tam sim no tau pom tus khub zoo tshaj plaws hauv cov duab ntawm USB 3.0 los sib txuas lus nrog lub computer.
