The model of the controller will have a large impact on performance as
well.  The latest fastest RAID controllers have dual core 1.2GHz CPUs
on them, where some slower ones still in produciton are using 333MHz
single core CPUs.  The quality of the firmware, the linux driver (or
windows, or bsd) all have a large impact on the performance of a raid
controller.

Definitely look into the battery backing unit.  But if it's a $250
card, then it might not be enough.
