I've bought 8 of them over the last 6 months. One was DOA. Right now they're
all in a linux md raid6 (LSI 9220-8i HBA) and working great. The reason I
selected this model is price per GB, TLER, and warranty.

This is one that I read before buying:

Agreed. I only get about 145 MB/s seq r/w on the outer edge of the spindle and
I'm guessing it will probably be around 80 MB/s on the inner edge. Definitely
not 15K enterprise drives. On the 8-disk raid6 I get about 130 MB/s rebuild,
1000 MB/s seq read.
