FYI, this SSD has a SATA interface.  The OS (and even the BIOS) is 
unaware that there is no spinning media.

I wasn't really thinking of flash wear-leveling as the drive's firmware 
takes care of that.  What I really had in mind was I/O efficiency, the 
use of algorithms that are particularly suited (or at least not 
particularly unsuited) to solid-state media.

Thanks for the response.
