西数SN770由于使用的是全盘模拟SLC的方案,虽然缓内空间很大,在空盘状态下达到了全盘的1/3容量,缓内写入表现良好,但是一旦遇上超大量的数据写入,SLC Cache耗尽后并没有TLC直写阶段,直接进入垃圾回收阶段的速度极其缓慢,出缓后速度一落千丈,写入速度只有400MB/s上下。 SolidigmP41 Plus没有使用全盘模拟SLC方案,缓内...
(usually) pseudo-SLC programmed flash that absorbs incoming data. Sustained write speeds can suffer tremendously once the workload spills outside of the cache and into the "native" TLC or QLC flash. We use Iometer to hammer the SSD with sequential writes for 15 minutes to measure both the ...

我不仅不推荐P41 PLUS,在现在阶段TLC都如此白菜,所有QLC都没购买价值。 海力士 今年下半年SSD价格都上涨不少,现在双11价格也明显高于618。不过还好有新玩家海力士入场,首发杀了一波价格。海力士是SOLIDIGM的母公司,因此在产品上有些就是互为马甲。 P41基本是SOLIDIGM P44 Pro的马甲(或者反过来说),1TB/2TB售价分别为...
Me: Can you confirm if the drive uses a WD controller or a SMI/Phison model? The NAND flash is BiCS 5? WD: The WD_BLACK SN770M NVMe SSD features 3D TLC NAND utilizing 112-layer BiCS5. In addition, confirming that Western Digital does not disclose controller specifics. Reactions: ...
