That's an awful big blanket statement. I think it really depends on what you are using the system for. We have a large SAP/Oracle system. It currently does way more reads then writes and writes are isolated to a few filesystems. We set up an A3500 with RAID5 LUNS and then striped across the LUNS using Veritas. Read performance is spectacular! Writes suffer a little but the striping helps to minimize the penalty, plus we don't do very many writes on these particular filesystems. While the RAID5 may have some performance hit the ability to keep going after a disk loss makes me feel a lot better..... But for things like logs, arch, temp space, roll backs I would avoid RAID 5.
