Western Digital AV-25

Why hasn't there been any talk about these in pc applications? I know these are meant for audio/video streaming devices, but everything about it seems fantastic.

Compared with the Scorpio Blue:

-32 v.
8 mb cache.
-4.2 v.
5.5 ms latency.
-22/25 v.
24/26 db noise
-1.6 v.
2.5 watt read/write
-0.65 v.
0.85 watt idle
-Rated 1 million hours mtbf
-500gb price is the same as Scorpio Blue

What am I missing about the performance of this hdd?
