Is this better than the Samsung 830 or the Sandisk Extreme?
Enough has been said about the 830, so I don't have much to add. The Sandisk Extreme isn't worth your time, unless you're getting it for considerably less than one of these. They sent me an Extreme to replace the Ultra that died on me after 5 months. It's been okay, but TRIM doesn't work properly (see the TweakTown articles) and that Sandforce controller has had a history of trouble.
