Thanks to both Joe and Billy. We are currently trying to optimize a fairly large production DB, and adding clustered indexes is part of the plan. The database gets steady inserts, updates from 50 workstations that hit primarily 13 tables. We plan to re-create everything from scratch and allocate enough space this time around to accommodate 5 years data input without the DB needing to grow. Fortunately we have lots of disk space to work with. We will then read the data back in from the archived database. We run a nightly maintenance job that rebuilds indexes leaving 20% free space. We have stopped the part of the job that shrinks the database, as we were noticing that there was 0 free space showing in EM. With heavy inserts and updates everyday, 0 free space doesn't seem appropriate.

We also were informed that the Sys Admin at the customer site had not been running ANY type of disk defragmentation in the last 2 years. The RAID 1 drive where our log file resides showed 46% overall fragmentation. The RAID 5 data drive showed 30% fragmentation. Yes I know that RAID 10 is better, but the server can't take any more drives.
