USB 2.0 vs 3.0: Chii Chinosiyana?

Chinjana Yekumhanyisa

Ah, mubvunzo wekare: zvinotora nguva yakareba sei kuendesa faira re10GB? Zvakanaka, kana uri kushandisa USB 2.0, iwe uri mukumirira kwenguva refu. Zvinokutorera anenge maminetsi mashanu, kana 282 masekonzi, kuti utore faira rako kwarinoda kuenda. Asi kana uri kushandisa USB 3.0, unogona kutsvoda iwo maminetsi mashanu zvakanaka! Iwe uchaitwa muchidimbu chenguva - 87 masekondi, kuve chaiwo. Ndiyo 225% nekukurumidza kupfuura USB 2.0!

Kutengesa Kumhanya

Kana zvasvika pakuchaja zvishandiso zvako, USB 3.0 ndiyo inohwina akajeka. Inogona kuburitsa yakapetwa kaviri kuburitsa kwe USB 2.0, ine huwandu hwe0.9 A kana ichienzaniswa ne0.5 A. Saka kana iwe uchitsvaga nekukurumidza kuchaja, USB 3.0 ndiyo nzira yekuenda nayo.

The Bottom Line

Pakupera kwezuva, USB 3.0 ndiyo inohwina akajeka kana zvasvika pakuendesa mafaera uye kuchaja zvishandiso zvako. Inokurumidza, inoshanda zvakanyanya, uye ichakuchengetedza mizhinji yenguva. Saka kana iwe uri kutsvaga kukwidziridza yako USB yekubatanidza, USB 3.0 ndiyo nzira yekuenda!

Maitiro ekutaura kana USB iri 3.0

Kuziva USB 3.0 neRuvara

Vazhinji vagadziri vanoita kuti zvive nyore kutaura kana USB iri 3.0 neruvara rwechiteshi. Kazhinji ibhuruu, saka haugone kupotsa! Iwe unogona zvakare kuona yekutanga SS (ye "SuperSpeed") yakadhindwa patambo kana padyo nechiteshi.

Mhando dze USB 3.0 Connections

Kune marudzi mana e USB 3.0 yekubatanidza iripo nhasi:

• USB Type-A - inoita seyakajairwa yako USB yekubatanidza. Ibhuruu kuisiyanisa kubva kune yekare USB zviyero.
• USB Type B - inodaidzwawo kuti USB 3.0 Standard-B, idzi dzine masikweya-kufanana muchimiro uye dzinowanzo shandiswa maprinta nemimwe michina mikuru.
• USB Micro-A - idzi dzakatetepa uye dzinotaridzika kunge dzine zvikamu zviviri. Ivo vanowanzo shandiswa kubatanidza mafoni uye zvimwe zvinotakurika zvishandiso.
• USB Micro-B - inoita kunge USB Micro-A mhando, ine yakatetepa uye maviri-zvikamu dhizaini. Zvinoenderana neMicro-A midziyo uye zvakare inoshandiswa kune smartphones uye zvidiki zvinotakurika zvishandiso.

Kuenderana neOlder Ports

Mimwe michina, tambo, kana ma adapter ane madoko ekare anogona kuenderana ne USB 3.0 midziyo, asi zvinoenderana nerudzi rwekubatanidza. Heino nhungamiro inokurumidza:

• Micro-A uye B zvinongoenderana ne USB 3.0 Micro-AB midziyo.
• USB 2.0 Micro-A plugs inoenderana ne USB 3.0 Micro-AB midziyo.

Kuti uwane iyo inokurumidza kufambisa mwero inokwanisika, ese maturusi aunoda kubatanidza anofanirwa kuve nerutsigiro rwe USB 3.0.

Inokurumidza USB Mitemo

Mumakore achangopfuura, kukurumidza USB zviyero zvakaburitswa. USB 3.1 (inonziwo SuperSpeed+) ine theoretical speed ye10 Gbps, uye USB 3.2 ine theoretical maximum speed ye20 Gbps. Saka kana iwe uchitsvaga ichangoburwa uye yakakura, iwe unoziva yekutarisa!

mhedziso

Mukupedzisa, USB 3 inzira huru yekufambisa data nekukurumidza uye nyore. Nekuenderana kwayo kumashure, unogona kubatanidza chero USB mudziyo kune chero chiteshi uye uchiri kuwana kumhanya kwakafanana. USB-C ndiyo yazvino vhezheni ye USB, ichipa kukurumidza kumhanya uye mamwe mapini ekubata ekugona kurinani kuchaja. Saka, kana iwe uri kutsvaga kukwidziridza yako data data mutambo, USB 3 ndiyo nzira yekuenda!

Mhoroi, ndini Kim, amai uye munhu anofarira zvekumira-famba ane ruzivo mukugadzira midhiya nekuvandudzwa kwewebhu. Ndine chido chikuru chekudhirowa uye mifananidzo, uye ikozvino ndiri kunyura nemusoro munyika yekumira-kufamba. Neblog rangu, ndiri kugovera zvandinodzidza nemi varume.
