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. > > vinum and ide on my system results is very poor disk performance, I > > see a 10-fold increase in read/write actions.

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. -D
