SSD and CCleaner

[Grump642]

I ran across this idea and did not know what to think. So I brought it here to the experts. CCleaner has a setting called "wipe free space" under Advanced options. It is claimed that this option will return a SSD to almost new performance, kind of like Trim. One guy said, using benchmarks as proof, that is even worked on 2 SSD's in Raid 0. Any thoughts on this?

doubt it.
"wipe free space" performs multiple write ops. 0's, 1's, 0's .. no erase ops as far as i know
i could imagine it helping to align all pages but it won't do what trim does, which is erase the page so that the controller can return it to the pool

Possibly on some SSDs. Sandforce SSDs can recognise when writing the same data over and over again (e.g. Writing 0s to wipe data). In this sort of case, they'll write the data once, but for the later writes it won't actually write, just point at the first sector - and add the new sector to the spare pool.

Just use HDDerase, as detailed other places on this forum.
