I-Optane, leli yigama u-Intel abhabhadise ngalo lo mugqa omusha we-SSD ngobuchwepheshe be-3D XPoint okuyinto eqa ngobuningi nangokulingana ngokuqhathaniswa ne-SSD yendabuko enezinkumbulo ze-NAND. Ngaphezu kwalokhu, sesivele sazi ukuthi ihambisana ngokuphelele nenqubo yokugcinwa kwe-NVMe i-Apple esivele iyisebenzisa kwamanye ama-MacBooks ayo, lokhu kusho ukuthi kungaba lula kakhulu ku-Apple ukwenza lobu buchwepheshe ku-Mac elandelayo amakhompyutha njalonjalo. thola inzuzo ethile kulobu buchwepheshe obusha.
Ukusetshenziswa kobuchwepheshe be-3D XPoint kuzosho ukwanda kwejubane kuze kube izikhathi eziyi-1000 ngaphezulu inkumbulo ejwayelekile kakhulu ye-NAND futhi kuze kube izikhathi ezi-1000 ezihlala ngaphezulu. Lokhu kungenxa yokuthi ngokusho kwe-Intel, kushubile izikhathi eziyishumi kune-DRAM.
Ukuqonda ukubaluleka kwe-Apple ye umthetho olandelwayo wesitoreji sakho se-NVMe (I-Non-Volatile Memory Express) kudingeke ukuthi ikhiphe isoftware ukuyisekela kwi-MacBook engu-12 intshi ngo-Ephreli wangonyaka odlule.
Lokhu kukhombisa ngokusobala ukuthi i-NVMe ihloselwe ukufaka esikhundleni sobuchwepheshe obudala be-AHCI, obabenzelwe khulisa ukusebenza kohlelo usebenzisa ama-hard drive ajwayelekile. Kodwa-ke, i-NVMe yenzelwe imisebenzi ephansi kakhulu yokugcina i-latency drive evame ukunikezwa ngama-SSD anememori engaguquguquki.
Uma kuqhathaniswa ne-AHCI, i-NVMe inciphisa ukubambezeleka ngamaphesenti angama-50. Isibonelo, i-Intel imaka i-latency kufayela le- 6 nanosecond SCSI / SAS izinhlelo kumijikelezo engu-19.500, kepha i-NVMe iyakwazi ukukwenza kuma-nanoseconds angu-2,8 nasemijikelezweni engu-9.100.
I-NVMe icace bha ukuthi ibe yisethenjwa esiyinkomba okungenani kule minyaka eyishumi ezayo, cishe umjikelezo wempilo ongaqhathaniswa ne-AHCI, eyaqala ngo-2004. Futhi kusukela ngo-2011, i-Apple ibilokhu isebenzisa ibhasi le-PCIe ukukhulisa umkhawulokudonsa kumayunithi akho, ngakho-ke usesimweni esihle soku sekela wonke umugqa we-Mac nge-NVMe futhi ngaleyo ndlela sihlanganise ama-Intel Optane SSDs ekuvuseleleni okuzayo.
