Mark, I forgot to mention (and was unable to measure) but the last hard drive upgrade that I did went WAY faster than I expected it to. And it was the largest yet - copying 60gb of data to an 80gb drive. Do you think sifted fids could have helped here? I started mid-evening and didn't have to wait for the copy over night per usual.

So even if people start using Jemplode's rebuld on PC option, it appears that fidsift has other benefits in player performance.
