ReadyNAS Duo v2 and larger then 4TB disks?

Question

My old beta Duo v2 unit&nbsp;is suffering&nbsp;a hard drive failure, and I'm pondering what to do with it long term.&nbsp;Currently it has two Seagate 2TB drives. Last week, the second drive went offline which it's done a few times over the years. Normally in the past a simple reseat would kick off a rebuild. However this time, Drive 1 was also starting to see some uncorrectable errors prior to the offline event. &nbsp;The strain from rebuild now has drive 1 up over 800 uncorrectable errors.&nbsp;Overall I'm not concerned with the data on it, as it simply provided online backups 24/7 when the noisier Ultra 4 unit might be offline. New drive time does open the question of how to move forward with&nbsp;the unit.&nbsp;The HCL only has one 4TB drive listed, and a handful of 3TB drives. A slight&nbsp;upgrade from the current&nbsp;2TB of available space.&nbsp;OS6 seems to be out of the question due to the newer ARM NAS units using a different ARM Core then the DUO V2 unit. Without a bitrot detecting filesystem, I'm not going to move the Duo v2 into holding primary data. Prior to this failure, I was pondering revamping my entire NAS setup later this year to get BTRFS or ZFS protection somehow.&nbsp;Has anyone else run any larger then 4TB drives in the Duo V2 and the ReadyNAS OS 5 releases? &nbsp;Ideally, if I could slot in 2x6TB drivesor larger, the unit could last me another few years without needing to be replaced.&nbsp;Thanks,-Tom

You should be able to use 4 TB drives in your NAS devices that run RAIDiator 5.3. The compatibilty list is just a list of tested drives we know worked when we tried it. You use unsupported drives at your own risk.&nbsp;
&nbsp;
OS 6 does have bit rot protection, so I am a little confused on why you don't think an RN2xx device wouldn't suit you (more RAM than RN100 series, better processor, more cores).&nbsp;
You would probably want to consider using new drives in an OS 6 box and then using backup job to move your data from NAS to NAS.&nbsp;

I think the OP was meaning to say that the v2 can't be upgraded to OS 6.

They can be upgraded to run OS 6 but it is not supported and would still require a factory default.&nbsp;OS 6 on 256 MB of RAM though is painful.&nbsp;

What I'd like to do is get a pair of 6TB or 8TB disks to put in the Duo v2. That would let me fully mirror my Ultra 4 unit, and then&nbsp;factory default it to&nbsp;run OS 6 there.

You could try it but I don't know if it would work. I think 8TB disks would be more risky than trying 6TB disks.
