Does anyone have experience fitting larger than listed drives to a Promise Pegasus2 R4? I have Seagate Enterprise Exos 10tb drives which I would like to use to increase the Promise Pegasus2 R4 capacity.

Can any end users report on their experiences with upgrading non specified drives in this unit? 

All previous answers from Promise tech support on over capacity drives has not been recommended purely because Promise never tested larger drives at the time.

I will be using the drive on an iMac (Retina 5K, 27-inch, Late 2014) running high Sierra. The drives will be used purely for backup of image data, not for processing.
