That sounds like you either have terrible luck or your power source is overvolting the SATA line.
Maybe.. the 3rd drive (OCZ) has lasted around 4 months now though with the same setup.
Don't get me wrong, I love SSD.. I shits all over both my old WD Raptor and 15k SCSI drive. I just make sure I don't put anything on it I want to keep and I have a backup computer ready to go at a moments notice..
