By the way, "freebsd-fs" is not an appropriate place to ask such questions. ccd is a device driver that implements a virtual disk, and not a filesystem. * 1. is there any [dis]advantage of using different size disks to be joined * together as a ccd? I don't think the size matters that much, but different speed (MB/s) seems to screw up the performance real badly. * 2. is using IDE disks for ccd good or bad idea? Never tried it. * More precisely: I've got some disks, IDE and SCSI, different sizes, * more or less useful as standalone. * I plan to test ccd for our newsserver with minimal expences. * What should I do? If you just want to test, as in see if it works, experience with the commands and setup, that's ok of course. If you want to do any serious performance measurements/tuning, you can only do that with the exact set of disks you are going to use for the news server. Satoshi
