I don't see why the 3 WDs wouldn't do well in a RAID 0 here. Certainly would
have enough drive connectors for 'em, so you could do software RAID as long as
the operating system supports it.
That's a pretty nice board. I'm reading an article here:
It says the chipset supports 4 SATA ports, and a RAID controller. With the RAID
controller then, you wouldn't have to do software RAID either. Appears to be a
very good article, with lots of benchmarks.
You can have 3 drive RAID arrays. The controller has to have at least 3
ports. They are usually 2 port or 4 port.
If you have Raptors in mind I believe that there is very little speed
improvement in a three drive array. The two drive array is running about as
fast as the computer and associated software will let it run. Usually
peaking to a little over 100MBs in a sustained transfer.
