This is actually quite easy. First off, look at the partition size. Is it a size that'll fit on just one disk? If so, then it's probably RAID 1. If the size of all partitions adds up to around the size of two disks put together, then it's either RAID 0 or JBOD.
Also, you can look to see if it has a partition table on each drive (which you'd expect for a RAID 1 mirror set) or you can just pick a random sector number (like 6,000,000) and see if the data matches between the two drives.
If it is a RAID 1 mirror set, you can just treat it like a single drive. Just know that it's possible that one drive could have been offline for some time and by out of date.
If it's not RAID 1 the next thing to try is assembling it as a JBOD which only takes a second. Just create a virtual volume set, put in the disk with the partitions first, then add the other and try opening or scanning it. If you find files that open it's a JBOD.
If that fails, then it's a RAID 0. Keep the drive with the partition table in as first, then the other, and just try every possible stripe size and see if you can open it and have files that open.
