The primary server is set up without raid, a pair of 73GB drives on  
separate channels of a split backplane, with the database files  
distributed over the two. At the time I didn't want to spend the  
money to go for redundancy. It hasn't bitten me yet, but it was  
probably a mistake. The secondary server is either a pair of 37GB  
drives set up as RAID 0, or 74GB drives as RAID 1, not sure since I  
had no involvement in the purchase and configuration.

I had been planning RAID 5 for the new server, but after more  
research, I think 1+0 is a better choice (my reading indicates 1+0 is  
better than 0+1). Tempting is RAID1/RAID1+0 on a split backplane, but  
of course then you need 6 drives which brings the price up...
