Yes. md uses block-devices independently of underlying implementation. > 2. Has anyone done this? Probably... =) > 3. How would this affect performance? Depends on the speed-characteristics of the underlying hardware and the characteristics of file operations your are going to perform. (Many small reads/writes vs large reads/writes.) On PATA/SATA the difference should'nt be that huge anyhow. > 4. Would it be better or worse than putting 2 IDE devices on one IDE > bus (master/slave like)? In case of drive failure, both disks will become unavailable in the case of 2 IDES on a single IDE channel. In your case: Get some SATA-drives, plug them in and make RAID. :) -- regards, Christopher Pharo Glæserud -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
