nvm-express-osx yosemite-10.10.3-0

Zosintha zaposachedwa za OS X Yosemite 10.10 zifika mothandizidwa ndi NVM Express (NVMe), protocol yatsopano yomwe imagwiritsa ntchito bwino mwayi wamagawo osungira a SSD.

Ambiri mwa mayunitsiwa amagwiritsidwa ntchito pano muyezo wa AHCI, kuyambira 2004. Protocol ya AHCI idapangidwa kuti izikhala yosungira makina osungira kwambiri ndipo makina atsopanowa okhala ndi mwayi wowerenga / kulemba mwachangu mwachidziwikire sanapangidwe, zomwe zimapangitsa kuti zisapindule nawo nthawi zonse.

Kupititsa patsogolo posungira kosasunthika monga kukumbukira kwa NAND ndi MRAM kwapangitsa kuti bizinesiyo ipange pulogalamu yabwino ya kuthana ndi malire a AHCI ndi kupitirira apo.

Zotsatira zakusinthika uku zimapezeka mu NVMe, chidule chofotokozera mtundu wosakumbukira wachikumbukiro ndipo womwe udapangidwa ndi kampani yopanga mamembala opitilira 80, chitukuko chidatsogoleredwa ndi zimphona monga Intel, Samsung ndi LSI. NVMe yamangidwa makamaka polumikizira ma SSD ndi PCIe NVMe, ndondomekoyi idapangidwa kuti izitha kukwaniritsa zosowa za makampaniwa pamene tikupita ku matekinoloje okumbukira mtsogolo, ndiye kuti, mwina tiwona momwe zingatengere impso za RRAM ndi MRAM zamtsogolo. zomwe zidziwike kumsika wosungira zisanafike 2020.

Phindu lalikulu la NVMe ndi kutsika kwake pang'ono kwa ma microsecond 2,8 poyerekeza ndi ma microseconds 6,0 a AHCI. Chifukwa cha kuchepa uku, nthawi yogwiritsira ntchito diski icheperachepera, makompyuta azikhala ndi nthawi yochulukirapo motero azithandiza gawo limodzi kukhala ndi batri lalitali. Kuphatikiza apo, pakhoza kukhala zochitika zina pomwe kuthandizidwa kwamapulogalamu abwinoko monga chitukuko cha protocol chimapitilizabe kuthandizira pakuchita bwino.

Chipangizo choyamba cha Apple pothandizira ukadaulo uwu ndi MacBook yatsopano ya 12 inchi Kuphatikiza pakukhala kotheka kuti zida zamtsogolo za Apple zizisangalalanso ndi NVMe.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.

  1.   haf anati

    izi zikutanthauza kuti ngati ndili ndi ssd, ndiyenera kuwonekera? kwa ine akuti 'Kompyutayi ilibe chida chilichonse cha NVMExpress. Ngati muli ndi zida za NVMExpress, onetsetsani kuti zalumikizidwa bwino ndikulowetsedwa. » ndili pakati pa 2012 MBP ndi samsung 840 evo.
