Now that I have evaluated the numbers and my needs a bit, I am really
confused about what appropriate course of action for me would be.
1) Use ZFS without GELI and hope that zfs-crypto get implemented in
Solaris and ported to FreeBSD "soon" and that when it does, it won't
come with such a dramatic performance decrease as GELI/ZFS seems to
result in.
2) Go ahead with the original plan of using GELI/ZFS and grind my
teeth at the 24 MB/s read speed off a single disk.

Our difference is that my hardware is already ordered and Intel Atom
330 + D945GCLF2 + 2GB ram is what it's going to have :)
