We've used some at work, (when I say some, over 1000) and we have had a failure rate of around 17%, this could be a bad batch, but it doesnt inspire confidence. But regardless of this, they are too expensive anyway. £300-£500 for 256Gb is a bit steep at retail when compared to 1TB HDD's. Also OS stutter, and no way to recover lost data, failure due to stong magnetic fields etc. I've read reports of some SSD's losing performance drastically when the OS is reinstalled as well. I'll stick with Raid HDD for now.
