Hi,

I did a 'draft' debian install on motsugo (the new martello) today, and 
thought I might run bonnie++ to test the ssd disk speeds before I wiped 
it. Here are the results for the curious:

Version  1.96       ------Sequential Output------ --Sequential Input- --Random-

Looks like money well spent! No ETA on when everything will be properly 
online yet...
