- baruch 14y agoThere are several background operations that happen on ssds, low or high end doesn't matter they all need them. I've seen quite a few supposedly high-end ssds that show abysmal behavior with wide variations in performance across time. SSD qualification is a tedious job. It's not even just about performance of the SSD the other points to care about are non-trivial if you intend to use lots of SSDs for important tasks.
