Stop ReadNAS synchronising
I have a brand new ReadyNAS 214, just set up with 4, as soon as the volume was created it set about synchronising? Synchronising what? The intended purpose for this NAS is to act as a file server...

I don't want it synchronising anything. How do I disable this?
The disks are being synced with each other. The system is basically creating the RAID array. Data and RAID recovery blocks are striped (spread) across the 4 disks. The RAID recovery blocks allow the contents of any disk to be recovered from the other three disks. That gives you some protection against routine disk failures, and also lets you upgrade to larger disks (or replace disks) in the future without down time. Note these data blocks are your "raw storage" - and the recovery blocks are needed even for the free space in your volume.
These RAID recovery blocks are being created in the background. You definitely don't want to disable this. If you managed to do it, the RAID array status would change to degraded or worse. Note the system performance will be sluggish until the process completes.
As an aside - although RAID redundancy is a good thing, your system is still vulnerable to data loss. System failure, power loss/surges, malware, fire/flood, user error, etc can all still result in loss of data. So you do need a backup plan for your NAS.
