How To Recover Data From RAID 5 if NAS Crashes

[wonmoi]

Could anyone advise how one could recover data from 3 or 4 disks in RAID 5 mode if the NAS it was in happened to crash for one reason or other?

Move the drives into a system that supports the filesystem type used on the drives.

Thanks thiggins for the advice.
Will the RAID array need to be re-established in the new system?
How can this be done?
