ReadyNas 3220 - allowable disc capaciites
I currently have a rack mount RS3220 fully loaded with 4 TB drives in RAID6 on OS 6.10.3. If possible I'd like to replace a couple of the drives that are starting to show increasing pending sector count with WD Red Plus 10 TB 7200 rpm drives. Is there any reason that will not work? I understand that when I replace the first drive I will not see any increase in available storage capacity but believe that when I replace the second drive the storage capacity should increase; Is that correct?
Thank you so much for all the wisdom you have shared and continue to share. Pat.

They are compatible, and I use several of these drives in my various OS-6 ReadyNAS. Seagate Ironwolf would also work.
Some would suggest that it is better to go with enterprise class drives for a 12 bay NAS (Red Pro, Ironwolf Pro, or other enterprise drives). All my ReadyNAS are desktop models, so I don't have personal experience on that.

Netgear does suggest making sure you have an up-to-date backup of the NAS before manipulating disks. I agree with that (and personally think that you should always have an up-to-date backup). That's particularly important if you have more than one drive that is starting to fail.

With RAID6 you'll need to replace four disks in order to see the storage increase.

Thank you, StephanB.
The drive manufactures recommend you use drives with vibration control in a 12-bay server, which pretty much every enterprise drive has. But the Red Plus also have it. Data from Backblaze, who run lots of drives in mutil-drive systems, don't indicate a significant difference in life between otherwise similar consumer (w/o vibration control) and enterprise drives, but they don't really talk about what drive mounting they use and whether or not is helps abate vibration. I use mostly enterprise drives in my 12-bay units, which I purchase used but with "low mileage", but I have used WD Red with success, and they don't have vibration control. The main thing is that you absolutely avoid SMR drives. But if you are staying above 6TB, that shouldn't be a problem AFAIK.
