Zithini umahluko phakathiI-USB 3.1 Gen 1kwayeIsizukulwana sesi-2?
I-USB 3.1 Gen 1kwayeIsizukulwana sesi-2: Ukutyhila umahluko obalulekileyo phakathi kweMigangatho emibini
Xa uthenga izixhobo zokugcina izinto zangaphandle, izitishi zokubeka iidokhi, okanye iilaptop, iintlobo ze-USB interfaces zidla ngokubhidisa, ingakumbi xa amagama anjeI-USB 3.1 Gen 1kwayeIsizukulwana sesi-2zivela rhoqo. Nangona zombini zingamalunguI-USB 3.1Kusapho oluqhelekileyo, kukho umahluko omkhulu ekusebenzeni nasekusetyenzisweni okusebenzayo. Eli nqaku liza kujonga umahluko ophambili phakathi kwezi nkcukacha zimbini ukukunceda wenze ukhetho olunolwazi ngakumbi.
Umahluko wesantya: Umahluko ongundoqo
Isantya esiphezulu sokudlulisa sethiyoriI-USB 3.1 Gen 1(ekuqaleni yayisaziwa ngokuba yiI-USB 3.0) ifikelela kwi-5 Gbps (malunga ne-625 MB/s). Esi santya sanele ukusetyenziswa kwemihla ngemihla, njengokudibanisa iimpuku, iikhibhodi, iiprinta, okanye ukudlulisa iifayile ezincinci ezifana namaxwebhu nomculo.
I-USB 3.1 Gen 2kwelinye icala, iphinda kabini le mda iphezulu ukuya10 Gbps(malunga ne-1250 MB/s). Oku kuthetha ukuba xa udlulisela iifayile ezinkulu, ezinje ngeevidiyo ze-4K, iifoto zefomathi ye-RAW, okanye iipakethe zokufaka imidlalo emikhulu, ixesha elifunekayo liya kuncitshiswa kakhulu. Umzekelo, ukudlulisela ifayile yemuvi ye-50GB ye-4K, iGen 2 inokonga phantse isiqingatha sexesha xa ithelekiswa neGen 1.
Isiseko soBugcisa kunye neNkqubo zokubhala iikhowudi
Umahluko wesantya usekwe ekusebenzeni kakuhle kweenkqubo zokubhala iikhowudi.I-USB 3.1 Gen 1isebenzisa iskimu sekhowudi ye-8b/10b, oko kuthetha ukuba yi-8 kuphela kwi-10 bits ezithunyelwayo eziyidatha yokwenyani, kunye nokusebenza kakuhle kwe-80%. Ke ngoko, i-bandwidth esebenzayo yokwenyani ye-5 Gbps raw rate imalunga ne-4 Gbps.
I-USB 3.1 Gen 2uphuculo luye kwisicwangciso sekhowudi se-128b/132b esisebenza kakuhle ngakumbi, nto leyo enyusa ukusebenza kakuhle ukuya kuthi ga kwi-97%, nto leyo evumela izinga le-10 Gbps ukuba libonelele nge-bandwidth esebenza ngokukhawuleza. Olu phuculo alugcini nje ngokunyusa isantya kodwa lukwanciphisa nokubambezeleka kokudluliselwa.
Ujongano oluPhakathi kunye nokuHlangana
Kubalulekile ukuqaphela ukuba zombiniI-USB 3.1 Gen 1kwayeIsizukulwana sesi-2banokusebenzisa iintlobo ezifanayo zojongano olubonakalayo, kuquka:
Uhlobo-A (ujongano oluqhelekileyo lwengxande)
Uhlobo-B (olusetyenziswa rhoqo kwiiprinta nakwezinye izixhobo)
Uhlobo-C (ujongano olujikelezayo lwe-oval)
I-USB 3.1 A ukuya kwi-Micro B(isetyenziswa rhoqo kwii-hard drive zangaphandle nakwezinye izixhobo ezindala ze-Android)
Kubaluleke kakhulu ukuqaphela ukubaUhlobo lwe-C lwe-USByimilo yojongano, hayi umgangatho wesantya. Ujongano lwe-Type-C lunokuxhasaI-USB 3.1 Gen 1, iGen 2, okanye neprotocol yeThunderbolt 3. Ke ngoko, isantya sokudlulisela asinakumiselwa kuphela ngesimo se-interface. Umzekelo, i-I-USB C ukuya kwi-USB AIntambo isenokuba nesantya sokwenyani esilinganiselwe yimigangatho yeendawo zonxibelelwano kuzo zombini iziphelo kunye nomgangatho wentambo, enokuba yi-5 Gbps yeGen 1 okanye i-10 Gbps yeGen 2.
Amandla okuPhuma koMbane
Ngokuphathelele umbane, phantsiI-USB 3.1 Gen 1umgangatho, ujongano lunokubonelela ngamandla aphezulu angama-4.5W (5V/0.9A). Ujongano lweGen 2, xa lusetyenziswa neprotocol ye-USB Power Delivery (PD), lunokuxhasa umbane ofikelela kwi-100W (20V/5A), owaneleyo ukutshaja uninzi lweelaptops kunye nokunika amandla iiperipherals ezisebenza kakuhle. Kufuneka kuqatshelwe ukuba xa usebenzisa i-Intambo ye-USB 3.1 A ukuya kwi-Micro BUkudibanisa izixhobo, amandla ombane adla ngokuthintelwa ziinkcukacha zezibuko zeMicro B, kwaye amandla adla ngokuba phantsi.
Iingcebiso Ezisebenzayo Zokusebenzisa
KhethaI-USB 3.1 Gen 1: Ifanelekile ukuqhagamshela izixhobo ezisetyenziswa ngokubanzi (iikhibhodi, iigundane, iiprinta), ukudlulisa amaxwebhu emihla ngemihla, okanye njengendlela yokutshaja ifowuni. Kubasebenzisi abanebhajethi encinci okanye iimfuno eziphantsi, izixhobo ezisekelwe kwiGen 1 zibonelela ngexabiso elingcono lemali. Umzekelo, ukuxhobisa i-hard drive endala yeselula ngesixhobo esiqhelekileyo.Intambo ye-USB 3.1 A ukuya kwi-Micro B, isantya seGen 1 sihlala sanele.
KhethaI-USB 3.1 Gen 2: Ukuba uhlala ufuna ukudlulisa iifayile ezinkulu (ezifana nokuhlela ividiyo, uphuhliso lomdlalo), uqhagamshele ii-SSD zangaphandle ezinesantya esiphezulu, okanye unethemba lokusombulula iimfuno zokutshaja iilaptop kunye nokudluliselwa kwedatha ngentambo enye, iGen 2 lukhetho olungcono. Ingakumbi kubasebenzisi beelaptop ezintsha,Intambo ye-USB C 3.1 ukuya kwi-USB Aokanye iadaptha exhasa iGen 2 inokuqhagamshela izixhobo ngokufanelekileyo kwiiperipherals zemveli okanye iihub ezinenani elikhulu lee-interfaces zeType-A, ngelixa iqinisekisa ukuhanjiswa kwedatha ngesantya esiphezulu.
Isikhokelo sokuChonga nokuThenga
Ngenxa yokudideka ekuqanjweni kwegama lemarike, nceda uqaphele oku kulandelayo xa uthenga:
Abanye abavelisi banokuthi babhale iilebheliI-USB 3.1 Gen 1njenge "I-USB 3.0"okanye" iSuperSpeed USB"
I-USB 3.1 Gen 2isenokubizwa ngokuba yi "SuperSpeedI-USB 10 Gbps"
Imigangatho yamva nje ye-USB iqanjwe ngokutsha:I-USB 3.1 Gen 1ngoku ihlelwe njenge "I-USB 3.2 Gen 1", kwayeI-USB 3.1 Gen 2ngoku "I-USB 3.2 Gen 2"
Xa uthengaI-USB C 3.1 ukuya kwi-USB Aor Intambo ye-USB 3.1 A ukuya kwi-Micro Bs, qiniseka ukuba inkcazo yemveliso ibonisa ngokucacileyo ukuba iyayixhasa iGen 1 (5 Gbps) okanye iGen 2 (10 Gbps) ukuze kuthintelwe iingxaki zokusebenza ngenxa yentambo.
Ukuqinisekisa ukuba ufumana ukusebenza okufunekayo, jonga ngononophelo iinkcukacha zemveliso endaweni yokuxhomekeka kuphela kwimo ye-interface. Ukuba kuyimfuneko, jonga amaxwebhu obuchwephesha asemthethweni.
Isishwankathelo
Ukhetho phakathiI-USB 3.1 Gen 1kwaye iGen 2 ngokuyintloko ibandakanya ukufumana ulungelelwaniso phakathi kwesantya, ixabiso, kunye neemfuno zokwenyani. Nokuba yinto entsha okanye chaI-USB C 3.1 ukuya kwi-USB Aisisombululo sokuguqula okanye iklasikhiI-USB 3.1 A ukuya kwi-MICRO BIndlela yoqhagamshelo, iGen 1 ibonelela ngesisombululo esithembekileyo nesingabizi kakhulu kwizicelo zemihla ngemihla, ngelixa iGen 2 ivula indlela ekhawulezayo kubasebenzisi abaziingcali kunye neemeko zokusebenza okuphezulu. Njengoko imfuno yesantya sokudluliselwa kwedatha kwizixhobo iqhubeka ikhula, ukuqonda la mahluko kuya kukunceda wenze izigqibo zobuchwepheshe ezikrelekrele kubomi bakho bedijithali.
Kwixesha elizayo, ngokwamkelwa ngokubanzi komgangatho we-USB4, isantya sokudluliselwa kwedatha siya kunyuka siye kwi-40 Gbps kwaye sidibanise iprotokholi yeThunderbolt 3. Kodwa kude kube ngoko,I-USB 3.1 Gen 1kwaye iGen 2 iya kuhlala ixesha elide, ikhonza iimeko ezahlukeneyo zesicelo kunye namaqela abasebenzisi ngokwahlukeneyo.
