Had a 120Gb version of these. It lasted 13 months. Got a replacement after a rma and sold it still sealed. That lasted 5 weeks with it's new owner!! OCZ support forums are full of tales of woe with 2E drives.
I've got a 2e in my laptop and don't find it all that great. Since fitting the laptop often locks up!
Could be my laptop but it was fine with my 160gb wd black.
