When it was evident that I was stuck with the drive, I opened it up. It's a sata card plugged into an adapter with a piece of foam to keep it in place. I've been meaning to try the sata card in a newer laptop and see if it can work there. It's not a mSata card, but it's still small enough to fit in the 2.5" enclosure with the ide-sata adapter. I don't know a lot about the various sata form factors, but I think it will fit in some of the newer laptops.
Kingspec makes (made?) some true pata ssd's. I've opened one of those and it's a single board (not a stack of adapters). In my testing they were slightly slower than the mSata/adapter combo, but still way faster than mechanical drives.
