3 out of 5 eggsWish it worked for me

Pros: Great idea if it worked.

Cons: My server (AM2/AM3 socket ASRock) would not even POST when the card was installed. This was an open-box so I don't know for sure if the problem is this specific card or the card in general.

Internal SATA cable connector does not lock or click into place. (There is only the male connector itself, but no surrounding shield to click into.) Be sure your internal cables have no stresses (zip-tie them nearby if possible) or they can easily come unplugged.

Other Thoughts: The "manual" is in very small print. By this point, there are more than a few of us geeks that no longer have the eyes of a 25-year-old.

The PDF manual is a so-so quality SCAN of this this tiny paper printout. Seriously? That just does not suggest attention to detail.

5 out of 5 eggsRuns like a dream...

Pros: I snapped a SSD card into it... ADATA XPG SX300 mSATA 128GB SATA III and now my HTPC boots in 8 seconds! I loaded Windows 7 Ultimate 64 and my machine is extremely fast and stable.

Cons: None whatsoever. What more do you want?

Other Thoughts: You can't go wrong with this baby...
