Re: Am I RAIDed or mirrored

[R Bruce Hoffman <bruce.hoffman@xxxxxxxxxxxxxxxxx>]

No, on raid5 with 4 drives you have 3x the storage of one drive.
On raid1 (mirror) you have half of 4 or 2x the storage of one drive.
One of the other services we provide is reading and checking the orders 
for things like raid/mirror specify.

WRKDSKSTS and press F11 to check how many drives and the protection.

Yes, you got 4G of ram.
