Because Vinum is being maintained, and because Vinum will allow you to stripe your disks instead of simple concatenate them, which will probably result in better I/O rates. > I just did a search on www.freebsd.org, and all I could find about Vinum > seems to imply that the software isn't ready for prime time.

And what do you do if ccd panics your system? ;^) This is just another facet of Grog's professionalism showing through. > Is Vinum ready for prime time? It had better be, since I've been using it to stripe 4 17 GB UWSCSI disks into a single 65 GB volume for about 3 months now. This is on a production server that churns 8-10 GB of new data every day - a web spider/filter machine. Vinum is much more actively maintained than ccd is, and has pretty much deprecated ccd. Vinum accomplishes all that ccd does, is simpler to use, and does much more as well. Try it, you'll like it. -- "Where am I, and what am I doing in this handbasket?"
