Umehluko phakathi kwesixhumi esibonakalayo se-U.2 ne-SATA E

I-interface ebonakalayo ye-SATA Express empeleni iwukuguqulwa kwesixhumi esibonakalayo se-SATA I.Isebenzisa kokubili isixhumi esibonakalayo se-SATA I nesixhumi esibonakalayo se-SATA esincane esinezixhumi ezingamaphini angu-4 kuphela.Isixhumi esibonakalayo esincane singamukela kuphela imigqa ye-PCI-E.Inzuzo yale ndlela ukugcina ukuhambisana emuva ngoba njengamanje, mancane kakhulu ama-hard drive e-SATA E atholakalayo, noma kungathiwa awekho nhlobo amamodeli athengiswa ngokusemthethweni.Ngokwenza lokhu, ngisho noma abasebenzisi bengenawo amadrayivu aqinile esixhumi esibonakalayo se-SATA Express, i-SATA E isengasetshenziswa njengezindawo ezimbili ze-SATA I, ivimbele noma yikuphi ukumoshakala.

I-interface ye-U.2 yabelana ngomqondo ofanayo nesixhumi esibonakalayo se-SATA E, kokubili kuhloswe ukwenza ngokugcwele ukuxhumana okukhona okukhona.Nokho, ukuze kuzuzwe umkhawulokudonsa osheshayo, isixhumi esibonakalayo se-U.2 siguqukile sisuka ku-PCI-E x2 saya ku-PCI-E 3.0 x4.Ukwengeza, yengeze ukusekelwa kwezivumelwano ezintsha ezahlukahlukene, njenge-NVMe, i-SATA E engenakho.Ngakho-ke, i-U.2 ingathathwa njengokuvela kokugcina kwe-SATA E.

I-interface ye-U.2 ohlangothini lwedivayisi ihlanganisa izici zombili izixhumi ezibonakalayo ze-SATA ne-SAS, igcwalise izikhala ngamaphini ashiywe isixhumi esibonakalayo se-SATA.Iphinde ihlanganise nomklamo wokhiye omise okuka-L ukuvimbela ukuxhumana okungalungile, okuvumela ukuhambisana nokucaciswa kwe-SATA, SAS, kanye ne-SATA E.Ohlangothini lwebhodi lomama, isebenzisa isixhumi esibonakalayo se-miniSAS (SFF-8643), kuyilapho ikhebula le-U.2 ohlangothini lwedivayisi lixhuma emandleni e-SATA kanye nembobo yedatha ye-U.2 hard drive.
