i've seen some people use usb sticks, and in practice it works on

allow for usb booting. Most of todays computers DO. Personally i
like compact flash because it is fairly easy to use as a cheap
alternative to a hard drive. I mirror the cf drives exactly like
they are hard drives so if one fails i just replace it. USB is a
little harder to do that with because they are just not as
consistent as compact flash. But honestly it should work and many
people do this.
This product looks really interesting:

But I can't confirm it will show both cards as separate disks…
My read is that it won't (which is supported by the single SATA data
connector,) but it will do the mirroring for you.
Turns out the FAQ page explains that it will not, too bad.
I know that I generally prefer to let ZFS handle the redundancy for
me, but for you it may be enough to let this do the mirroring for the
root pool.
I'm with you there.
It seems too expensive to get 2. Do they have a cheaper one that
takes only 1 CF card?
I just ordered a pair of the Syba units, cheap enough too test out
anyway.
Oh. I was looking and if you have an IDE socket, this will do separate
master/slave devices:
(no IDE cable needed, it plugs right into the MB - There's another that
uses a cable if you prefer.)

And 2 of these (which look remarkably like the Syba ones) would work too:

They're only 30 each so 2 of those are less than the dual one.

Now to find some reasonably priced 8GB CompactFlash cards…
Thanks,
