Ii-NVMe SSDs: Ngenxa yokusebenza kwesantya esiphezulu kunye nomthwalo onzima wokusebenza, ii-NVMe SSD zinokutshisa kakhulu. Uninzi lwee-NVMe SSD ezisebenza kakhulu ziza kunye ne-heatsinks eyakhelwe-ngaphakathi okanye iindlela zokunciphisa i-thermal ukunciphisa umngcipheko wokutshisa. Izisombululo ezisebenzayo zokupholisa ezifana neefeni ze-M.2 okanye izibiyeli zokupholisa ze-PCIe zinokunceda ngakumbi ukulawula ubushushu.
Ngokumalunga nokusebenza kakuhle kwamandla, ii-SATA SSDs zisebenzise amandla kancinane kusetyenziso ngokubanzi. Nangona kunjalo, ii-NVMe SSD zibonelela ngokusebenza ngokukhawuleza kwiindleko zokusetyenziswa kwamandla aphezulu kunye nokuveliswa kobushushu. Ukukhetha i-drive efanelekileyo kuxhomekeke kwiimfuno zakho zokusebenza kunye nokuba uzimisele ukutyala imali kwizisombululo ze-thermal ukuze usebenze ngesantya esiphezulu.
