I can not comment on "most vendors" but for the PROGRESS RDBMS RAID5 is definitely not recommended. It will work but you will see a significant reduction in performance. We strongly recommend that our clients go with RAID10 (as in RAID 1+0). In-house we only use RAID10.
+1 Write performance of RAID5 on hardware MegaRAID SATA 150-6D is *very* poor.
