RAID0 Setup Question

I've got 4-200GB Seagate drives. I would like to setup in Raid 0 in my new system with the first 2 drives. They show up st 184GB in the Raid Controller Bios. When I created the Raid Array and in Windows install, it shows the array of having a capacity of 372GB?

I though running RAID0 would let 2 drive only have the capacity of the smallest drives, in my case shouldn't the capacity be 184GB in the array?
 
Nope.

RaidO splices data to both drives so OS looks at both physical drives as one drive of 372GB.

What you were thinking is Raid1.
 
If you did this to increase data safety (RAID1 mirroring) you've accomplished the exact opposite, since RAID0 gives you roughly double the chance of data loss compared to a single drive in exchange for its better performance. And roughly 4x the chance of data loss compared to RAID1.
