You mean like my FSF Membership Card/Boot drive?

I have a couple of Compact Flash to SATA adapters, but I don't have a 40GB (or larger) CF card or Microdrive. I'm booting 
my frontend from a Hitachi 4GB Microdrive with one of these adapters and it works fine, but no better than a 2.5" HDD. I 
did it mainly to gain more space for rotating drives in the case. The Microdrives seem faster than CF cards.

I have wondered if the SSDs are actually better in any way than USB sticks (maybe better wear leveling or caching 
algorithm?) I also wonder if the Linux SATA drivers might be better than the stack that drives the USB sticks. 
Transferring large files to and from a USB stick on my desktop seems extremely slow, and uses a lot of CPU for some reason, 
but that's another issue.


Just about anything made these days will boot from a USB device, so the question would be if using a SATA device is better 
in any way than a USB drive.
