What is the advantage of RAID vs. a single drive where both have the
same mb's?

Thanks,

RAID 0 striping uses two or more drives to boost performance. Data is
spanned acrossed the drives and all data is lost should one drive have
problems. You are able to use the full capacity of each drive
as long as they are the same size.

RAID 1 mirroring keeps an identical copy of one drive using
another. You only have access to the main drive.

RAID 0: Faster, but riskier.

RAID 1: Data integrity, but lose 1/2 total HD capacity.

RAID 10: Best of both of the above.

RAID 5: Good for hot-swap requirements.
 
also remember each method takes a certain number of drives to impliment it.
This can be a concern depending on how many drives your system supports and
how many drives your case can hold.

RAID 0 uses as many HD's as you want. the more, the faster, the riskier.
RAID 1 uses 2 drives (typically) with a ending capacity of 1 drive (but
safer of course)
RAID 1\0 Uses a minimum of 4 drives.
RAID 5 Takes a minimum of 3 drives but can be as many as you want.
