You can't take advantage of U160 without at *least* three disks. ; )
If you have enough RAM for the cache, and you're not using fsync(), then
an insert/update doesn't actually hit the disk, it just returns. The
kernel can update the disk later at it's leisure. I'm not sorry that I
spent all of the money for the large array that I use, it provides
redundancy that lets me sleep easier - but I can guarantee that I'm not
using 1/100th of it's potential as far as write capabilities.
