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.
