Comparing performance of RAID config. levels. Need to format each time?

post #1 of 3
Thread Starter 
I'm looking to compare read/write performance of an array of 3 Seagate Barracuda 7200.12 HDDs in various configuration levels as part of a school research project.

I have a working knowledge of configuring hardware RAID implementations albeit I'm not sure if I can replace my existing configuration (RAID 1 - 2 drives) with RAID 0, 3, 5 by changing the settings in the BIOS/RAID menu accessible on startup without formatting the drives.

Note: ONLY interested in hardware RAID.

In a word yes. Once you change the array (beyond extend/expand/shrink) it will rebuild the array and have to re-do the parity config for the drives. Your best bet is to have a spare drive that you can boot from or clone from once you rebuild the array.
