If you are backing up over 1Gbit/s ethernet then you require a storage that can write at a maximum of 100mbytes/s and either configuration should be more than capable of handling way more than that, assuming that it never gets ridiculously fragmented. If you use RAID5 then I recommend a hardware RAID controller with battery backed write cache, although it's less of a requirement for "streaming" storage than random access database storage where small (< stripe size) writes are frequent. I would start by looking at how fast Bacula can push things on to disk. I wonder if there is a way of backing up to /dev/null so this can be measured? Once you have that figure then you can think about what sort of disk throughput you need.
