Just thought I'd chime in here. I installed a 32GB Patriot Warp 2 as my PC's OS drive and that slowed SOME things down drastically. Apparently there is a bug in the SATA controller that slows down random access.
If I do a read/write test on the drive, I get 150MB/s.
Doing things like application installs/uninstalls takes a lot longer, opening photoshop is slower. In fact, aside from sustained (large file copies) transfers I find the drive slow.
Two benefits are that it is really quite and tiny!
This is likely fixed in other SSD drives, but be careful which one you get.
