I am curious how the 710 or S3700 stacks up against the new M500 from
Crucial? I know Intel is kind of the goto for these things but the m500
is power off protected and rated at: Endurance: 72TB total bytes written
(TBW), equal to 40GB per day for 5 years .

The M500 is fine on paper, I had that one on my list of things to evaluate when I can. The general reliability of Crucial's consumer SSD has looked good recently. I'm not going to recommend that one until I actually see one work as expected though. I'm waiting for one to pass by or I reach a new toy purchasing spree.

What makes me step very carefully here is watching what Intel went through when they released their first supercap drive, the 320 series. If you look at the nastiest of the firmware bugs they had, like the infamous "8MB bug", a lot of them were related to the new clean shutdown feature. It's the type of firmware that takes some exposure to the real world to flush out the bugs. The last of the enthusiast SSD players who tried to take this job on was OCZ with the Vertex 3 Pro, and they never got that model quite right before abandoning it altogether.
