Noids brings up a good question. I remember reading somewhere that you need like 20% of the disk free so the drivers can move things around properly to maintain their speed. For your disk that would means something like 10-15GB should be free. I have one of the 80GB Intel SSDs and one of the other things I noticed was that it has gotten slower over time (couple months). I think I read that they do that the more you read and write to it but you shouldn't be seeing that yet with a new drive.
