These are exactly the SSD's I'm referring to that suffer from SATAe 
internal interface overheads.  I would caution everyone to make sure you 
try before you buy with these guys.

If you have the cash, FusionIO does native PCIe interfacing with the 
internal flash packages, and therefore truly delivers the numbers 
they're reporting.  Not sure about Virident, but those are traditionally 
solid devices as well (also expensive however).  I think Micron also has 
a native PCIe device in the wild now, the P320h?  Anybody know of other, 
native PCIe devices?

Best,
