Its fast, its light, it fits in a slim perfectly with the memory stick door still attached. Love it love it love it, got 2 16 GB SDHC cards and can store my games library on it, 50 games and counting with 5 gigs left over. Put it in a Star Wars Limited Edition and its quite frankly, beastly. I would highly suggest this storage solution for anyone who just plain needs more storage. Had to yank out the UMD drive of course, but who uses those anymore. It took like 50 minutes to xfer over 30 gigs of software, on a Pro Duo woulda taken hours. I cant recommend this mod enough. I used a packing peanut so that it has a cushion behind it and hot glue. Looks clean, was fast to install and with the peanut it has a shock absorber of sorts. Just thought id let you guys know if anyone was on the fence about this thing. Tom
