Lifetime of an SSD drive

An SSD should last you several years even if you put scratch files, paging file, and a database that's updated every millisecond on it. In all likelihood, you have some other problem.

You did an excellent experiment by doing a reinstall to an old SATA HDD. If that one failed in a few months, too, then either you have phenomenally bad luck or something in your system is chewing up and spitting out drives. I hope that you have external backups of all your data.

You can download and run manufacturer's diagnostics for the three drives you mention. I'm not sure if your problem is corruption of the data on the drive or actual damage to the drive.

I suggest that you do a SECURE_ERASE on the SSD, this will reset everything on the SSD and restore some performance. This is crucial if there's a driver or controller problem. Also check to make sure that the firmware is up to date. You can do all of this from the partedmagic liveCD (great rescue tool) which can be obtained here

Many manufacturers offer warranties on their SSDs which exceed 2-3 years. Consider getting an RMA replacement because an SSD should last around 3-5 years, not 6 months to 1 year. If you want an SSD with a long life, get one of the Mushkin Chronos Deluxe or Samsung 830 as these use Toggle NAND flash which has a much longer lifetime.
