If memory serves, this is what I ordered on a couple of my new 2450's... The 100MHz i960RX with 128MB cache. I'm planning to run some tests in RAID 1 and 10 modes. I'm not sure I fully understand why a lot of people are so caught up on RAID 5. RAID 1 seems fast and reliable given a decent controller with good recovery options, and RAID 10 sounds like a better solution with a larger quantity of drives. I plan to test with RAID 1 mirrors setup on different channels, and then stripe across the channels/mirror sets just to see what kind of numbers I get - has anyone already tested this setup? -mrh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
