Thanks Greg. I'd be very interested in what you find. To address the other responses, 1. the raid-1 configuration had 24 mirrored disk sets (48 spindles total). The raid-5 configuration also had a total of 48 spindles. 2. I'll be glad to send the whitepaper to anyone who requests it.

We are using HDS 9960 boxes, and the file systems will be setup as a RAID5 on the SAN as compared to RAID0+1 on the EMC frames that we have.. I believe the RAID5 issue is related on to aHDS disk sub-system.. I'm trying to get some info from our HDS rep now..... greg -----Original Message----- Sent: Monday, October 28, 2002 5:24 PM To: Multiple recipients of list ORACLE-L Hi, I just got forwarded a whitepaper from Hitachi and Oracle, that compairs raid 5+ and raid 1 using the TPC-C benchmark test suite. The claim is that raid 5 is as fast or faster. While I'm waiting for a comparison or raid 5+ with raid 0+1, I thought I'd take a poll with the list. The benchmark is using the Hitachi 7700E. Has anyone heard other recommendations attributed to Oracle that are pushing raid 5+ as the configuraton for "unrivaled performance"? Has new disk technology changed the general conception that raid 0 or 0+1 provides better performance than other raid levels?
