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.

And what do you do if ccd panics your system? ;^)
This is just another facet of Grog's professionalism showing through.

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.
