You can't turn off the cache that is used for wear leveling. It doesn't let you because the drive wouldn't work at all. When it erases a block, where do you think it would keep the previous contents until it has to write the modified data back?

My second quote suggests what it says. When you click the turn off cache button in windows, there is no stuttering. We are clearly talking about the write buffer at that point as I've already said wear leveling cache can not be disabled.

It lets you turn off the write buffer because that is just for performance purposes. You can turn off the read/write buffer an an HDD too. Will be 5-10x slower. It is the same idea but SSDs don't suffer anywhere near as much. My point stands, the X25 would not stutter even with a 0kb write buffer. It would be slow, but it would not stutter. Stuttering is due to bad controller design and not due to cache. Cache can somewhat remedy the bad controller design, but if the controller is fine to begin with then there is nothing to remedy.

Simple question, if I disable cache on my x25-m in windows, how much cache is it using to remain operational?
