PS3 & SSD

[Keoeson]

I looked into those after people were saying this. From my reading Hybrid drives will not work on game systems because they need some kind of software or something to learn what you use most often and store that to the faster part of the drive. So it would just be a normal HDD with faster read speed and not a true SDD functionality when used in a console.

There are drives likes this, but I think they're called dual drives. If you search for SSHD you should find the right thing. These drives handle the SSD cache transparently and the drive firmware decides what to cache. The write speeds won't be much better, but that's not really important for gaming.
I've got one in my PS3 and it works great.
