I was just wondering if anyone had any info on the usable size of the 146-GB drives from NetApp. I am trying to figure out how many drives I'll need, but I can't really tell without knowing what my usable space will be.

If it helps, here's some data I have collected from other drives.

18 GB disk - becomes 17.0 GB because of disk overhead (right size) - becomes 14.923389 because of OS overhead - becomes 13.431053 with a 10% snap reserve - becomes 11.938713 with a 20% snap reserve

36 GB disk - becomes 33.917 GB because of disk overhead - becomes 31.776308 because of OS overhead - becomes 27.273826 with a 10% snap reserve - becomes 25.421048 with a 20% snap reserve

72 GB disk - becomes 67.906 GB because of disk overhead - becomes 59.747608 because of OS overhead - becomes 53.772850 with a 10% snap reserve - becomes 47.798088 with a 20% snap reserve
