I-SODIMM DDR5 Imemori ye-laptop mainboard enhle nembi enezinjongo ezimbili enokuhlolwa okulula kwekhadi lokuhlola Ukutholwa kwesikhala sememori

Yiziphi izici zezintambo ze-SAS kanye nezintambo ze-SAS

Ikhebula le-SAS liyinkambu yokugcina yemidiya yediski iyidivayisi ebaluleke kakhulu, yonke idatha nolwazi kufanele lugcinwe kumidiya yediski. Isivinini sokufunda idatha sinqunywa yi-interface yokuxhuma yemidiya yediski. Esikhathini esidlule, besilokhu sigcina idatha yethu ngokusebenzisa izixhumi ze-SCSI noma ze-SATA kanye nama-hard drive. Kungenxa yentuthuko esheshayo yobuchwepheshe be-SATA kanye nezinzuzo ezahlukahlukene ukuthi abantu abaningi bazocabanga ukuthi ikhona yini indlela yokuhlanganisa i-SATA ne-SCSI, ukuze izinzuzo zazo zombili zidlalwe ngesikhathi esisodwa. Kulesi simo, kuvele i-SAS. Amadivayisi okugcina axhunyiwe angahlukaniswa cishe ngezigaba ezintathu ezinkulu, okungukuthi, i-middle-end ephezulu kanye ne-near-end (Near-Line). Amadivayisi okugcina aphezulu ikakhulukazi ayi-Fibre channel. Ngenxa yesivinini sokudlulisa esisheshayo se-Fibre channel, amadivayisi amaningi okugcina i-optical fiber asetshenziswa ekugcinweni kwedatha yokhiye wezinga lomsebenzi omkhulu. Idivayisi yokugcina ephakathi nendawo ikakhulukazi amadivayisi e-SCSI, futhi inomlando omude, isetshenziswa ekugcinweni kwedatha ebalulekile yezinga lokuhweba. Ifushaniswe ngokuthi (SATA), isetshenziswa ekugcinweni okukhulu kwedatha engabalulekile futhi ihloselwe ukufaka esikhundleni sekhophi yokusekelayo yedatha yangaphambilini kusetshenziswa itheyiphu. Inzuzo engcono kakhulu yamadivayisi okugcina i-Fibre Channel ukudluliswa okusheshayo, kodwa inentengo ephezulu futhi kunzima ukuyinakekela; Amadivayisi e-SCSI anokufinyelela okusheshayo kanye nentengo ephakathi, kodwa anwetshiwe kancane, ikhadi ngalinye lesikhombimsebenzisi se-SCSI lixhuma amadivayisi afinyelela ku-15 (isiteshi esisodwa) noma angu-30 (amashaneli amabili). I-SATA ubuchwepheshe obuthuthuka ngokushesha eminyakeni yamuva. Inzuzo yayo enkulu ukuthi ishibhile, futhi ijubane alinciphi kakhulu kunesikhombimsebenzisi se-SCSI. Ngokuthuthuka kobuchwepheshe, isivinini sokufunda idatha se-SATA siyasondela futhi sidlula isikhombimsebenzisi se-SCSI. Ngaphezu kwalokho, njengoba i-hard disk ye-SATA ishibhile futhi ibiza kakhulu, ingasetshenziswa kancane kancane ekulondolozeni idatha. Ngakho-ke isitoreji sebhizinisi sendabuko ngoba uma sicabangela ukusebenza nokuzinza, nge-SCSI hard disk kanye ne-fiber optic channel njengesikhulumi esiyinhloko sokugcina, i-SATA isetshenziswa kakhulu kwidatha engabalulekile noma kwikhompyutha yomuntu siqu yedeskithophu, kodwa ngokukhula kobuchwepheshe be-SATA kanye nemishini ye-SATA evuthiwe, le modi iyashintshwa, abantu abaningi baqala ukunaka i-SATA ngale ndlela yokuxhumeka kwedatha yochungechunge.
