280MB/s<300MB/s, due to the "compatibility" based design of SSD's,
while SSS, w/o a legacy controller, can do 800MB/s out of a single
drive.
  

I have not heard about these SSS you mention.
Do you have a link?

Also are you sure that the SATA/SCSI layer is the problem? Some hardware 
raids can do 800 MB/s sequential, single stream, and indeed with a 
SATA/SAS interface to the kernel. If what you say was true, that would 
be impossible...
