USB interface yog siv wildly hauv ntau thaj teb, kev sib txuas lus, tab sis koj puas paub qhov sib txawv ntawm USB 2. {} Thiab USM 3}}? USB 2. {0 yog cov laus tiam USB interface, USB 3.} Yog cov khoom siv tshiab thiab cov ntaub ntawv siab dua kis tau. Thov saib hauv qab no kom paub ntau ntxiv ntawm lawv qhov sib txawv.
1, kis ceev
USB 2. {{{{}}: The theoretical tus nqi hloov pauv yog 480 Mbps (kwv yees li 60 MB / s) nws feem ntau {4} mb / s.
USB 3. {{{{{{}}: The theoretical tus nqi hloov pauv yog 5 {4}} Mb / s, thiab ntau dua hauv qee qhov xwm txheej.
2, interface tsos
Color identification: USB 2.0 interfaces are often black or white, while USB 3.0 interfaces are mostly blue.
Pin quantity: USB 2.0 socket has 4 pins, USB 3.0 socket has 9 pins, and a metal shielding layer is added internally to improve stability.

3, Khoom Siv Hluav Taws Xob
USB 2. {{{{{{}}: Qhov nyiaj tshaj tawm hluav taws xob tshaj plaws yog 500 ma (nrog lub zog ntawm kwv yees li 2.5 w).
USB 3. {{{{{}}
4, Cov Ntaub Ntawv Kis Cuam Cab
USB 2. {{{{{}}: Adopts ib nrab ntawm hom duplex, thiab tuaj yeem tuaj yeem xa cov ntaub ntawv uas tsis sib xws nyob rau tib lub sijhawm.
USB 3. {{{{{}}: Adopts tag nrho cov hom dupirection, txhawb nqa cov ntaub ntawv cuam tshuam nrog, thiab muaj peev xwm ntau dua.
5, kev sib raug zoo
Rov qab zoo: USB 3. {{0}}}}}}}}}}}}} 0; USB 2. {{{{}} Cov khoom siv kuj tseem tuaj yeem ntsaws rau USB 3. {{} Interfaces rau siv.
6, Daim Ntawv Teev Npe
USB 2. {{{{}}}: Haum rau cov khoom siv ceev (xws li nas, cov ntawv hloov chaw) lossis cov ntaub ntawv hloov me me.
