For Michael, I think raid5 is not a bad choice: - if you're going to have multiple TB of data, using JBOD gives a pretty harsh limit to your compaction/anticompaction scenarios - he is concerned about his data set size, so so raid 1 or 10 "wastes" space - raid0 is potentially painful since you'd have to transfer a lot of data to repair every time a single disk dies

If you must use RAID, RAID0, 1, or 10 would be better. > -Brandon
