How Long t Initialise?

[freg]

Hi

I have just received a new HFR2-SU3S2 Pro Raid enclosure.

I have just installed 4 x HGSt Helium enterprise 8TB drives.

I have set the unit to RAID 10

The front panel shows power on, fan mode auto and low speed, USB 3 connection and disk activity on all 4 drives

It is connected to an iMac running High Sierra 10.13.4

I used Paragon v15.2.319 NTFS For Mac to initialise the RAID as a 16 TB Windows NTFS drive for use connected to our Smart TV holding our 4K HDR video media.

Paragon recognised the enclosure as a single 16TB drive as expected that was uninitialised.

Starting the initialisation, the drive was unmounted, erased with a warning that all data would be lost, then its at creating file system structures with the progress bar at about 0.25% and no movement for the last couple of hours.

It has been sitting on the desk with lots of drive activity and drive lights flashing for over two hours.

How long should this process take?

Thanks
