+1 from me ... I have been using RaidFRAME on both my net5501 and
net4801 hosts and an external USB disk enclosure without issues
this has saved my metaphorical bacon more than once with dead disks in
the past ...
also, one thing that helps when using autoconfigured software RAID
devices is that the disk later becomes more portable, in the sense that
it will also boot successfully in any other host - once the kernel is
up, it will refer to filesystems by /dev/raid<n> so the fact that the
kernel found the disk as /dev/wd<n> or /dev/sd<n> as it booted makes no
difference ... very very handy for recovery operations
This experience comes from NetBSD but should also be applicable to other
*BSDen and Linux to some extent ...
 apart from the 2day synchronisation time on a 150GB drive with the
net4801's USB 1.1 support ... :)
 in fact I generally set up my laptop for day-to-day operations as a
broken RaidFRAME mirror for this very reason.
 Linux seems to have a slightly more robust method for identifying
locations of filesystems on the same device regardless of device path
