Optane, eli ligama apho i-Intel ibhaptize lo mgca omtsha we-SSD ngeteknoloji ye-3D XPoint emele umtsi wobungakanani kunye nomgangatho xa kuthelekiswa nee-SSD esele zineenkumbulo ze-NAND. Ukongeza koku, sele sisazi ukuba ihambelana ngokupheleleyo ne-NVMe yokugcina iprotocol esele isetyenziswa yi-Apple kwezinye zeeMacBooks zayo, oku kuthetha ukuba kunokuba lula ukuba i-Apple ithathe le teknoloji kwiikhompyuter zeMac ezizayo kwaye ngaloo ndlela ifumane ezinye. inzuzo kobu buchwepheshe butsha.
Ukusetyenziswa kweteknoloji ye-3D XPoint kuya kuthetha ukunyuka kwesantya ukuya kumaxesha angama-1000 ngaphezulu eyona nkumbulo ixhaphakileyo ye-NAND kwaye ukuya kuthi ga kwi-1000 amaxesha ahlala ixesha elide. Oku kungenxa yokuba, ngokutsho kwe-Intel, iphindwe ka-10 kune-DRAM.
Ukuqonda ukubaluleka kweApple ye Iprotocol yakho yokugcina yeNVMe (I-Non-Volatile Memory Express) kwafuneka ikhuphe uhlaziyo lwesoftware ukuyixhasa kwi-12-intshi yeMacBook. ngoAprili wonyaka ophelileyo.
Oku kubonisa ngokucacileyo ukuba i-NVMe yenzelwe ukubuyisela iteknoloji ye-AHCI endala, eyenzelwe ukuba ukwandisa ukusebenza kwenkqubo abasebenzisa iihard drives eziqhelekileyo. Nangona kunjalo, i-NVMe ilungiselelwe imisebenzi yokugcina idrayivu ene-latencies ephantsi kakhulu eqhelekileyo ebonelelwa zii-SSD ezinememori engaguqukiyo.
Xa kuthelekiswa ne-AHCI, i-NVMe inciphisa i-latency ngepesenti ze-50. Ukwenza umzekelo, i-Intel ibeka i-latency kwi Iinkqubo ze-6 nanosecond SCSI/SAS kwimijikelezo ye-19.500, kodwa i-NVMe ilawula ukuyenza kwi-2,8 nanoseconds kunye ne-9.100 cycles.
I-NVMe yenzelwe ngokucacileyo ukuba ibe yi-protocol ye-go-to-protocol ubuncinane kwiminyaka elishumi ezayo, ngokumalunga nexesha lokuphila elinokuthelekiswa ne-AHCI, eyaqala ngo-2004. ngoko ke ikwimeko entle ukuba bonelela ngenkxaso yeNVMe kuwo wonke umgca weMac kwaye ke ngoko udibanise iiyunithi ze-Intel Optane SSD kuhlaziyo oluzayo.
