Pretty much anything that you consider to be a reliable supplier will =
do.  There are no specific FreeBSD requirements as far as I know.

I recommend that you get a disk that is externally powered instead of =
with power supplied over USB.

Earlier versions of FreeBSD had problems with USB connected devices.  In =
particular if they were removed or powered down without dismounting, =
this could lead to a kernel panic.  This problem has been fixed, but I =
still am extra careful with my USB backup disks:

(1)  Power for the back-up disks should be on a UPS
(2)  umount the file systems on the back-up disk when not in use.

Cheers,
