Optane, iri izita iro Intel akabhabhatidza nayo iyi nyowani mutsara weSSD ine 3D XPoint tekinoroji inova huwandu hwakawanda uye hwehunhu hwakaenzaniswa neiyo yatove yechinyakare SSD ine ndangariro dzeNAND. Pamusoro peizvi, isu tatoziva kuti inoenderana zvizere neNVMe yekuchengetedza protocol iyo Apple yatoshandisa mune mamwe maMacBook ayo, izvi zvinoreva kuti zvinogona kuve nyore kuti Apple iite kugamuchirwa kweiyi tekinoroji mune inotevera Mac makomputa zvichingodaro. wana mukana kubva kuhunyanzvi uhu hutsva
Iko kushandiswa kweiyo 3D XPoint tekinoroji kunoreva kuwedzera nekukasira kusvika anosvika ka1000 zvakapetwa iyo yakajairika NAND ndangariro uyezve kusvika ka1000 zvakapetwa zvakanyanya. Izvi zvinodaro, sekureva kweIntel, iri gumi kakapetana kupfuura DRAM.
Kuti unzwisise kukosha kweApple ye yako NVMe yekuchengetedza protocol (Non-Volatile Memory Express) yaifanirwa kuburitsa software yekuitsigira pa12-inch MacBook muna Kubvumbi wegore rapfuura.
Izvi zvinoratidza pachena kuti NVMe inoitirwa kutsiva tekinoroji yekare yeAHCI, iyo yakagadzirirwa kuwedzera mashandiro ehurongwa uchishandisa zvakajairika zvakaoma zvinotyaira. Nekudaro, NVMe yakagadziridzwa kune yakaderera kwazvo latency yekuchengetedza mota mashandiro ayo anowanzo kupihwa nemaSDD ane-asina kugadzikana ndangariro.
Kuenzaniswa neAHCI, NVMe inoderedza latency ne50 muzana. Semuenzaniso, Intel inoratidza latency mu 6 nanosecond SCSI / SAS masisitimu pamamiriyoni 19.500, asi NVMe inokwanisa kuzviita muma 2,8 nanoseconds uye 9.100 macircule.
NVMe yakajeka yakagadzirirwa kuva chirevo cheprotocol kweanenge makore gumi anotevera, ingangoita hwakaenzana hupenyu kutenderera kune AHCI, iyo yakatanga muna 2004. Pamusoro pezvo, kubvira 2011, Apple yanga ichishandisa bhazi rePCIe kuwedzera bandwidth. Muzvikamu zvako, saka iwe uri munzvimbo yakanaka ku tsigira iyo yose Mac mutsetse neNVMe uye nekudaro inosanganisa Intel Optane SSDs mune iri kuuya gadziriso.
