Umahluko phakathi kwe-U.2 kunye ne-SATA E interface

Ujongano lomzimba lwe-SATA Express luhlengahlengiso lwe-SATA I interface.Isebenzisa zombini i-SATA I interface kunye ne-SATA encinci ye-interface eneziqhagamshelo ze-4-pin kuphela.Ujongano oluncinci lunokwamkela imigca ye-PCI-E kuphela.Inzuzo yale ndlela kukugcina ukuhambelana okubuyela ngasemva kuba ngoku, zimbalwa kakhulu ii-hard drives zeSATA E ezikhoyo, okanye kunokuthiwa akukho naziphi na iimodeli ezithengiswa ngokusemthethweni.Ngokwenza oku, nokuba abasebenzisi abanayo i-SATA Express interface hard drives, i-SATA E isenokusetyenziswa njengojongano lwe-SATA I ezimbini, ukuthintela nayiphi na inkcitho.

I-interface ye-U.2 yabelana ngengcamango efanayo kunye nojongano lwe-SATA E, zombini zijolise ukwenza uninzi lwezinto ezikhoyo zokusebenzela.Nangona kunjalo, ukufezekisa i-bandwidth ekhawulezayo, i-interface ye-U.2 iye yavela kwi-PCI-E x2 ukuya kwi-PCI-E 3.0 x4.Ukongeza, yongeze inkxaso yeeprothokholi ezintsha ezahlukeneyo, ezinje ngeNVMe, esweleyo yiSATA E.Yiyo loo nto, i-U.2 inokuthathwa njengelona tshintsho lokugqibela lwe-SATA E.

I-interface ye-U.2 kwicala lesixhobo idibanisa iimpawu ze-SATA kunye ne-SAS ye-interfaces, ukuzalisa izithuba ngezikhonkwane ezishiywe yi-SATA interface.Ikwabandakanya uyilo olungundoqo olumise okwe-L ukukhusela uqhagamshelwano olungalunganga, ukuvumela ukuhambelana ne-SATA, i-SAS, kunye neenkcukacha ze-SATA E.Kwicala le-motherboard, isebenzisa i-miniSAS (SFF-8643) i-interface, ngelixa ikhebula le-U.2 kwicala lesixhobo lidibanisa amandla e-SATA kunye nedatha yedatha ye-U.2 hard drive.
