I know and I am sorry for that. It was just bad timing. I asked for help and
then within 24 hours found that I needed a lot of storage really fast. I had
to make a decision whether or not to figure out what went wrong or to get on
with the task as hand.

I have 4 ata133 ide disks, all identical. They run off a promise ata133 io
card.
With vinum, all 4 disks are accessed at pretty much the same time, no matter
what you do. Without, you only access the disk that you are writing to. It
goes a lot faster but I have to manage my data usage more.
I dont blame vinum, I blame my ide subsystem.
