You won't necessarily be able to access the disk as just a normal disk, but you should be able to instruct you local system to access it as part of a degraded RAID-1 array and read the data just fine.
If you need to do this and are using hardware RAID, you would need the same kind of card, or in case of software RAID you would need the same software.
Note that some implementations make it look like the disk is a normal disk with a normal disk header, but I would be very wary of just using it as-is; the RAID information might conceivably be tucked in there somewhere and ruin your day.
