I currently have a 2 disk raid1 implemented via 3ware hardware raid. The 3ware card makes the ide drives appear to be SCSI drives to the kernel, so SCSI disconnect logic/etc. is supported. Currently I use unused space on the raid 1 array to hold my snapshot lv. I also have a standalone ide 80 GB drive in the system with lots of unused space (~40GBs). There are 2 contradictory performance statements that can be made: 1) raid 1 w/3ware should be much faster than a JBOD ide. 2) snapshots hosted on a separate physical media are faster. Is this a clear cut case of moving my snapshot lv to the ide drive would be faster, or do I need to do performance testing to be sure?
