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. >> So basically on this system: >> >> unencrypted ZFS read: ~70 MB/s per disk >> >> 128bit Blowfish GELI/ZFS write: 35 MB/s per disk >> 128bit Blowfish GELI/ZFS read: 24 MB/s per disk > I'm in the same spot as you, planning to build a home NAS.

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