Are 4TB disks supported on the ReadyNAS PRO 2?

Hi,

I'm looking at upgrading the capacity of a ReadyNAS Pro 2 box to two 4TB disks. The box is running RAIDiator 4.2.27 (an upgrade to 4.2.28 is planned as well).

Checking the HCL (http://kb.netgear.com/app/answers/detail/a_id/20641) I see 3TB and 4TB disks are supported. However, the release notes for 4.2.27 (and 28) state "Maximum 2TB drive support on 3200/4200 V1 channels 5-12 due to LSI controller limitation.".

What does this mean? That we can insert the 4TB disks but only 2TB would be used?

Please advise.

Thanks!

You don't have a ReadyNAS 3200 or a 4200, so that restriction doesn't apply. 4 TB drives are supported on the pro 2.

  Ah, OK, got it. I wasn't sure how I needed to interpret the 3200/4200 reference.
  
  Thank you for your quick reply Stephen!

    The 3200 and 4200 are legacy 12-bay rackmount ReadyNAS units that used a LSI controller for drive bays 5-12 that is limited to 2TB disks. The 4200 v2 doesn't have this limitation.
    
    The Pro 2 is a 2-bay desktop ReadyNAS.
