I read with some alarm about trouble with SuperMicro servers and ATA, 
because that is my new box.  I'll chime in a data point saying that I 
have not seen any errors with the SuperMicro 1U and my 250G Western 
Digital SATA drives:

The vendor (ASA) were initially reluctant to send me this box because 
they were keen to issues with FreeBSD's SATA chipset compatability, but 
I did some research and convinced them not to fret.

I am saving money and probably some hassle by replacing 3ware with 
gmirror.  My cheat sheet is posted at .
