Intel英特爾於OpenWorld大會上,展示與美光合作的3D Xpoint技術,去來取代NAND快閃
記憶體,且也能當記憶體使用,而且儲存密度是DRAM的十倍、壽命和性能更是快閃記憶體
的1000倍,可用來取代NAND和DRAM。
展示的測試軟體數據中,以3D XPoint為基礎的NVMe SSD,IOPS高達70300,延遲僅有9μ
s(微秒),IOPS比目前的NVMe SSD快上4.42倍(NVMe SSD IOPS為15900),延遲更低了86.44
倍(NVMe SSD延遲58μs),效能可以說是大獲全勝,而且在另一款測試軟體顯示出來的兩
者效能差距更大,3D XPoint NVMe SSD IOPS為95600,NVMe SSD則為13400,差距7.13倍
,而3D XPoint NVMe SSD延遲為9微秒,但NVMe SSD延遲則是73微秒,差距高達8.11倍,
可以說是3D XPoint NVMe固態硬碟效能可以說把NVMe SSD遠遠拋於後頭。
除了PCIe傳輸介面的Optane 3D Xpoint 固態硬碟硬碟外,3D XPOINT還可做成DDR4記憶體
介面,除了可為NAND,另外還可以當成DRAM使用,因此要實現記憶體斷電資料不遺失或許
已不在是難事。
