Hi all!


I am trying to upgrade disk for my Promise Pegasus 2 R6.


Now there are 6 3T HDD.

I am evaluating to get more small SSD for it.


I have read the PDF "Pegasus-PT-HE154ZMA_PDF"

  • Page49: • Drive Interface – SATA 1.5Gb/s or 3Gb/s 
  • Page125: • •Interface – SATA 3 Gb/s or 6 Gb/s 

So I'm confused. anyone can help to provide the advice what is the highest spec of SSD SATA I can buy for my R6 ?



Thank you very much !!

The easiest way to changing the RAID level or migrating with higher capacity drive is to take backup of the existing data available in the unit and delete & re-create with RAID 6 array because manual migration may take days or may be months.
