Needless to say I would recomend the first idea unless you can find
another 40GB drive and another controller, and use 4x pieces to make a
120GB pool. But for best performance its best to allocate full drives
so ZFS can activate write caching on the drives.
James Dickens
its cheaper to power one box, than 5. You
will also need to budget differently for disks, adding 3-5 disks at a time
instead of a single disk, but your data will be safer.

I heard a story about a customer complaining about his higend server
performances; when a guy came
over, and then add the 3rd disk to the pool. perhaps that would be a

to cope with solutions like these.

ZFS + rsync, backup on steroids.
I was thinking today about backing up filesystems, and came up with an
awesome idea. Use the power of rsync and ZFS together.
Start with a one or two large SATA/PATA drives if you use two and
don't need the space you can mirror other wise just use as in raid0,
main (4, ffbff69c, 20860, 20800, ffbff7aa, 20400) + 148
00012858 _start (0, 0, 0, 0, 0, 0) + 108

not an expert, but most if not all compression is integer based, and
I don't think floating point is supported inside the kernel anyway so
it has to be integer based.
