How much free space do you have in the database?? Make sufficient free space in the database to contain the rebuilt object (or better 3 or 4 times the...

1) Ditto on the RAID 5/RAID 10 performance stuff. Don't go there.

2) Why did you get such different drive types? Are they all 15KRPM? Will a 300GB...
