I could of course just drop back to a simple mirror and forget RAID5, but I really want that extra 250Gb.



One other thing I noticed, is that the RAID5 had substantially greater throughput on large sequential reads (like copying big files around -- .flac or .mpeg2 for instance.

On RAID1 (Linux soft) the throughput was the same as for a single drive on reads. For RAID5 it was more like a RAID0 -- 3 drives in parallel. 71Mbytes/sec vs. 210Mbytes/sec.
