The momentus is a Terrrrrribllllleeee drive. Our work has them on 50+ computers and 40% of them have failed in the first 4 months of use. They have terribly high failure rates. And nothing would suck more than being mid turn 5 in bcb at 40% and you 90k and your ps3 says the game is corrupt and you have to change drives and reinstall.
Steer clear of seagate alltogether, they are not the company they used to be. Get a legit SSD, their not that expensive, or find a hyprid made by WD. WD makes solid drive especially if you can find a Black Version Hybrid. Black is WD's server grade drives.
