三星生產什麼樣的快閃記憶體,也就決定了SSD市場未來的技術走向
三星闡釋了下一步的快閃記憶體演進路線圖。首先是現款產品的更新
規劃中的新品有970 EVO Plus、PM981a、PM983a(數據中心用)和PM991
分別是針對970 EVO、PM981、PM983和PM971a的升級改款。
其中970 EVO Plus和PM981a容量配置不變(250GB~2TB)
其依然採用64層3D TLC,不過順序寫入速度將獲得提高
PM981a同時在隨機速度上也有改良。當前1TB 970 EVO的順序寫入是2500MB/s
250GB是1500MB/s。PM991相較PM971a,隨機讀寫、順序寫入將翻番,順序讀取預計提升
50%。
接下來是QLC產品線。
企業級(含OEM)產品的命名規則是,MLC使用SM,TLC使用PM
QLC將採用全新的BM開頭型號。三星在會上公佈了四款QLC SSD
包括BM1733、BM9A3(企業級NVMe)、BM1653(SAS)和BM991(消費級)
消費級的QLC新品為860 QVO和980 QVO,前者是SATA 3,後者是M.2 NVMe。
快閃記憶體本身的推進方面,三星預告明年二季會拿出512Gb的QLC顆粒
號稱比對手的延遲低。
