The motherboard contains the RAID controller which configures the drives. In the limited experience I have had with this, drives had to be reconfigured and data restored from backup.

So I do not think you can do this, based on my own experience.

That realy depends on the NAS...... and the method fo raid used.

Some NAS have hardware raid, but often they also can used Software raid....
In the first case you need a chassis that is the same as the original (without disks) and the NAS need to be able to import an existing raidset...
YMMV i have no experience here.

If it is software and the OS uses Linux things are a bit easier..., having the same type of chassis help but is probably not needed.
QNAP, Synology and some others are Linux based and for QNAP i am sure they use softraid. (There is hardware assistence on the MoBo for comparing large blocks of data but it basicly uses a standard  volume method used on all linuxes.).

the reason i ask as in my previous experience i has a server raid card die and i replaced it with another different card but it was the same brand but different model a much more advanced card, en i replaced the card the card auto recognised the drives and the server booted up.

hence the question i was wondering if the nas would do the same

It depends on the controller on the board

Don't bother telling us the make / model number of the NAS or controller. we'll just guess.

the only way you can get that imo is on ebay; look for a second hand, or one with a bad drive...

As andyalder said its important to know the model and make of the controller. If it is a software raid based one such as nexentastor or some opennas based solution then it is easy to restore. If not then it might be a bit more complex. If the data is important then DON'T INITIALIZE THE DRIVES IN THE NEW PURCHASED CONTROLLER. IT WILL ERASE ALL YOUR DATA!!!! I might be able to help you recover it.

NAS != NAS != NAS....  ie. To get a useful answer tell your make & model of your NAS.
Without it it will continue to be guess work (at best)....
