Ukuvuselelwa kwakamuva kwe-OS X Yosemite 10.10 kufika ngokusekelwa kweNVM Express (NVMe), umthetho olandelwayo omusha osebenzisa kangcono amandla wamayunithi wesitoreji se-SSD.

Iningi lalawa amayunithi asetshenziswayo njengamanje izinga le-AHCI, elisukela ngonyaka ka-2004. Iphrothokholi ye-AHCI ekuqaleni yayenzelwe imidiya yesitoreji se-high-latency futhi la madrayivu amasha anokufinyelela okulula kokufunda / ukubhala ngokusobala kwakungahlosiwe, okwenza kube nzima ukuthola okuningi kuzo zonke izimo.

Intuthuko ekugcinweni okungashintshi okufana nezinkumbulo ze-NAND ne-MRAM kuholele umkhakha ukuthi wakhe isibonisi esingcono se-software bhekana nemikhawulo ye-AHCI bese uqhubeka.

Umphumela walokhu kuziphendukela kwemvelo utholakala ku-NVMe, isifinyezo sokuchaza uhlobo lwenkumbulo ezwakalayo engeyona eguquguqukayo futhi eyakhiwa yinkampani yezimboni enamalungu angaphezu kwama-80, intuthuko yayiholwa yiziqhwaga ezifana ne-Intel, i-Samsung ne-LSI. I-NVMe yakhelwe ngqo izindlela zokuhlangana ze-SSD ne-PCIe NVMe, le protocol yakhelwe ukuthi ikwazi ukuhlangabezana nezidingo zemboni njengoba siqhubekela kubuchwepheshe bememori yesikhathi esizayo, okungukuthi, mhlawumbe sizobona ukuthi kuthatha kanjani izintambo zeRRAM ne-MRAM yesikhathi esizayo ezokwethulwa emakethe yokugcina ngaphambi kuka-2020.

Inzuzo enkulu ye-NVMe ukubambezeleka kwayo okuphansi kwama-microsecond 2,8 kuqhathaniswa nama-microseconds angu-6,0 we-AHCI. Ngenxa yalokhu kubambezeleka okuphansi, isikhathi sokusetshenziswa kwediski sizokwehla, ikhompyutha izosebenzisa isikhathi esiningi ingenzi lutho ngakho-ke izosiza ngokwengxenye ukuthola impilo yebhethri ende. Ngokwengeziwe, kungaba nezimo ezithile lapho ukusekelwa okungcono kwesoftware njengoba ukuthuthukiswa kweprotocol kuqhubeka nokusizwa ngokusebenza.

Idivayisi yokuqala ye-Apple ekusekeleni lobu buchwepheshe yiyona iMacBook entsha engu-12 intshi ngaphezu kokuba ngaphezulu kokungenzeka ukuthi amadivayisi we-Apple azothokozela i-NVMe.
