I've had the same drive for almost 2 years, and I have no problems. I have a separate spinning rust drive which I use for my swapfile and for downloads, and of course all my large files are on my fileserver.

I also have had an OCZ Agility 2 in my laptop for about a year now, and that drive hosts a (small) swapfile. No problems.

Both these systems run Linux.

No: I've had my OWC Mercury Extreme Pro for 8 months now and haven't had a single issue.
