I have inherited what I believe is a ReadyNAS 6 Pro.  The model is listed simply as RND-6B.  I was wondering if any of the Seagate Enterprise or NAS 8TB offerings such as the ST8000NM0055 would work with all bays filled in Raid 5, so 40 TB storage plus the parity drive.  Anyone know?  I can't find any info on what the actual drive limits might be with this device.

These drives aren't on the compatibility list (although if you have a used NAS it doesn't matter, since Netgear won't support it anyway).

 

If you use 4.2.x firmware then there is no technical reason why 6 ST8000NM005 drives wouldn't work.  However, the unit would be unable to expand - you'd need to have all disks in place when you did a factory reset, and you wouldn't be able to go upgrade to 10TB later on w/o another reset.

 

However, you could switch over to OS 6 (which is possible but not supported by Netgear).  Then you'd have the ability to expand (plus the other benefits of the newer OS).

 

I don't recommend using the archival (SMR) drives in the NAS..

 

RAIDiator 4.2.16 allows for drives larger than 2 TB to be used by using GPT partitioning instead of MBR --  the last version of RAIDiator 4.2 is 4.2.28, and it should technically support 8 TB drives even though no drives are on the compatiblity list (since we wouldn't have tested unreleased drives during the development cycle of RAIDiator 4.2).

 

I'm not a money tree so I haven't purchased any 8TB drives to try this out though myself, but I don't see where the problem would be.
