Fire up Disk Utility.
It's located in /Applications/Utilities

If the disk are in mirror, it's not using Hard RAID, as that would use RAID5.
But you can open the RAID Utility in the same location - it will complain if there is no Hardware RAID card installed.

You can also open System Profiler, to get detailed info on your hardware.

Under Disk Utility, I saw the RAID type is Mirror RAID set, So I think it is software RAID, mirror means two HD.

There is no RAID utility program under /Applications/Utilities.

Ok, if you can see the RAID in Disk Utility, then it's a Software RAID.
