There are a few products which claim to allow RAID-like
arrangements with IDE drives. They're not common or standard.

In a hardware RAID configuration, a controller card manages the
physical drives (it will come with configuration software) and the
"drives" that the OS sees are RAID volumes managed by the controller.
In a software RAID configuration, the OS sees the physical drives
and links them together into sets. Not all OSes can do this --
amongst Windows, this is unique to NT (and presumably also Win2K).
There are two key reasons to prefer a hardware implementation,
despite the cost of the controller ($300 and up):
1. RAID management can steal CPU time away from your applications.
2. If the OS is managing the RAID array, you can't boot from the
array -- you need a non-array boot volume in the software-only case.
