For this capacity, you can't really get a better price for SSDs. The performance is very average - look at benchmarks and you'll find it's pretty much in the center of the charts.
I would like to point out that this drive lacks a lot of SMART features. There were only about a dozen; they're basically enough to tell you whether the drive is still working properly. I have seen consumer-level drives that likely had 50 features, or more. Not a big deal, but I'm guessing this is one of the reasons this is so cheap.
