三星970系列固态盘现身:4bit QLC闪存[Migage]

NVMe是对SATA时代AHCI的一种取代,现在已经成为判断一块SSD属不属于高端、性能优不优秀的直观标准之一。在NVMe固态盘市场,Intel 600p的地位不言而喻,它在很长一段时间都是最便宜的NVMe SSD。 不过,TMHW已经拿到了三星PM971固态盘的相关资料图。当然,这是BGA封装的产品,并不会在零售市场面向终端用户贩售。

参数上,PM971设计为22mm x 16mm x 1.5mm多芯片封装,包含三星的Proton主控、LPDDR4内存、V-NAND闪存(3bit TLC\4bit QLC都有)。

性能方面,PM971 512GB的连续读取最高3000MB/s、写入最高900MB/s,而比自己高一阶的PM981的写入最高是1800MB/s。

4K随机存储方面,190K IOPS读取、170K IOPS写入。

据悉,PM971将提供128GB、256GB和512GB三种容量。其消费级对应的2.5寸SATA3/M.2固态盘将是970系列,传闻三星从这一代开始,不再使用EVL/PRO而是直接970和980系列。
