Dear Forum

I have a Pegasus2 R6 and its working with 6x8TB Harddisks. So i need more space and I'm planing updating to 6x18TB Harddisks. 

Is this working with the controller? Is someone using the Pegasus 2 with 18TB Harddisks?


Thank you for your help.

 The maximum HDD that was tested was 10TB. Since it is a legacy product, no further drives have been tested hence Promise cannot gurantee the compatibility of any untested drive outside of the compatibility list even though the untested drives should work.

Kindly find the HDD compatibility list below for the Pegasus2 R6 .

Hi, thank you so much for this information. But i know that my old raid is already EOL and this means also the list from promise is old. I was wondering if someone has real world up to date informations for me ;)
