There are two aspects to snapshot performance: 1) Normal io to an origin or already copied area 2) Time taken to perform a copy on write exception We normally recommend people put their snapshots on a seperate physical volume in order to minimise seeking for (2). However your raid volume will probably be faster than the IDE for (1). So which drive is best is going to depend on your use of the volume, if your data isn't changing much, then you should probably optimise for (1). Maybe you should do some benchmarks :) - Joe _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
