Newer DRAM-less drives like Samsung’s 980 M.2 PCIe 3.0 SSD line can tap up to 64MB of your CPU’s DRAM to keep track of mapping instead of using DRAM at the SSD level
三星说能节约大概64m内存

三星说能节约大概64m内存[/quote]……这段话是说会占用最多64MB的内存

这段意思是三星无缓存的ssd会占用至多64MB的系统内存

那不就是有缓存比无缓存节约64m吗?
缓存简单来说就是更快
能不能提高系统运行效率要看你怎么用,是不是频繁读写
一般来说只要没快过内存导致出bug是速度越快肯定越好 但你要考虑100秒快十倍能十秒完成 0.1秒快十倍是0.01秒完成这种情况
至于寿命 其实消费者级别的场景不怎么需要管寿命

据说能增强一点随机4k性能
但是现在的tlc SSD性能,做系统盘其实很溢出。所以只要不是啥辣鸡牌子,就随便买吧
