Ready NAS Upgrade
I'm ready to upgrade my 2 x 2 bay ready nas units to a 626x ready nas 6 bay unit to expand my storage capacity.
Can I set the 626x up to show and have 3 x 12Tb drives instead of 1 only and if so is it difficult ??

Assuming you mean you want three separate volumes, the answer is yes, by putting the unit in FlexRAID mode. Of course, you are eliminating the use of RAID redundancy, putting the data at higher risk of loss due to drive failure.
My main question is why? If your thought it that it would be easy to simply remove a drive and save it as a backup, a NAS is not really intended to be used that way. And if you think reading that drive on another system will be easy, be aware that each will be an mdadm "RAID1" with one missing drive and a BTRFS file system on top of that. Not something your average computer can access.
If you are just looking for more space and don't care if the data is lost, then three separate volumes is certianly better than three concatenated ones (w/o redundancy). If one drive fails, you only lose its contents with separate volumes. With concatenated drives, you lose everything.
I would like 3 seperate 12Tb volumes set up in raid 0. Thank you.

That's self contradictory. You either want 3 separate JBOD volumes (which "under the hood" are RAID1 missing a drive) or one RAID0 volume of all drives concatenated.
Assuming you mean 3 JBOD, start by inserting one drive and letting the NAS create one JBOD volume. Then, on the Volume page, switch off XRAID. Now, when another drive is inserted (which is best done with power on), you'll have the option to make it a separate JBOD. Note that if you fail to switch off XRAID before inserting another drive, the NAS will automatically use it to replace the "missing" drive in the RAID1 and you'll have to start over.
If you wonder why a "JBOD" is really a non-redundant RAID1, it seems pretty clear it's so converting to a redundant RAID1 is significantly less complex. But Netgear doesn't divulge their thought process or make this a well known fact.
