Thank you for all of the responses. I have been thinking about adding another disk and going to RAID5. I don't care about write performance, because the major applications (FTP and mp3blaster) are pretty much read-only. In fact, even read performance just doesn't matter. It's only 256kb/sec + overhead, which you can get off of a CDROM. You're right: I'm not sharing, so its just for a jukebox application on the home stereo and a file server for the empeg. Since I already have 3 160GB drives, the incremental to go to raid5 is only about $200 or so. I think, however, that I'll lose my filesystem when I go from raid0 to raid5, so it will be a hassle to migrate.
