Another possibility could be to use lvm and lvmcache to throw a ssd in
front of the spinning disks. This would only improve things if
you didn't otherwise fill up the cache with data -- you want
the cache to contain inodes. So this might work only if your
ssd cache was larger than whatever amount of data you typically
write between rsync runs, plus enough to hold all the inodes
in your rsync-ed fs.
I've not tried this. I'm not even certain it's a good idea. It's
just a thought.
