Hi,I have a ReadyNas Duo with 2TB that are quickly filling up. I have been hoping that it would be possible to use 3TB disks when they get more common, but it doesn't seem so. Is the problem with compability connected to the hardware itself or is it a firmware thing? I have been very happy with my Duo, but are very reluctant to go for an other ReadyNas with larger capacity in case it will also be a dead end regarding firmware updates or whatever it takes to be able to upgrade disks after a while.Keep checking back every other week or so, but the compability list doesn't grow. Will it ever?Hoping for some good solutions here...-iau

The Duo v1 (runs RAIDiator 4.1.x) is a Sparc ReadyNAS. It's the last of line a products released beginning in 2004. Unfortunately 3rd party development for the Sparc platform largely ceased a long time ago now. For this reason GPT support is highly unlikely to be added to Sparc ReadyNAS. GPT support is necessary for 3TB drive support.Both the ARM ReadyNAS (Duo v2, NV+ v2) and x86 ReadyNAS (e.g. Ultra, Pro) support 3TB drives. These two platforms have strong 3rd party development and it is expected that for the foreseeable future higher quality drives will be able to be qualified over time for these platforms (though firmware updates may be required to add compatibility). A user in the ReadyNAS community has tested some 4TB drives in a few x86 ReadyNAS units and found them to be working. Whilst this is by no means conclusive it is a good sign that 4TB drives may already be compatible with x86 ReadyNAS units.If you want a ReadyNAS with the longest useful life I'd go with an x86 ReadyNAS.Welcome to the forum!

Thanks for the reply! I'll take a look at those you mention. At least I know what to look for in a new ReadyNAS. I have been very happy with my Duo and it has been very stable. Will I be able to easily move what is on my current Duo to a new ReadyNAS (Ultra or Pro) by simply inserting one of my existing hard drives?

The ARM and x86 disk formats are not compatible. So you will need to restore from backup (or start with new drives and use Frontview backup to load it)

While StephenB addressed the drives formatted in the ARM units, the same applies to the Sparc units. The Sparc units drive format is incompatible with both the x-86 and ARM formatting. You would have to either start the new unit with at least one drive and copy the data over the network. You might want to consider keeping both the Duo and the drives intact. After you set up the new unit with larger drives and move all your data over, you could then set the Duo up to automatically back up part of the new unit that contains important and critical files.

Thanks for your replies. Yes, I will keep the Duo and find some use for it. Always in need of an extra backup! I'll mainly be using it for a home network to access data like pictures that are stored on the server. Will the Pro offer any advantages over the Ultra for this? Noise and temperature are my main concern. I'll have to do some research in one of the other forums for this, I guess, so thanks again.

Two very different products with very different hardware, OS etc.

Duo v2 (runs RAIDiator 5.3.5 and available for purchase from Nov 13th 2011) supports 3TB drives

Duo v1 (runs RAIDiator 4.1.x or earlier) supports disks up to 2TB in capacity.

So... has anybody been able to run anything larger than 2TB drives in their ReadyNAS Duo V1?

It doesn't do it. 2 TB is the limit.

Thanks, I was hoping someone had hacked the firmware or controller to allow it by now. I guess I need to look at V2...

Or the x86 models (pro-2 or ultra-2)

v1 readynas duo not supporting 3TB kinda sucks...but i'm hoping the work around is to to simply use the usb ports on it.

FYI there is a good background article on why things changed when hdds jump from 2TB to 3TB...
http://www.pcworld.com/article/235088/e ... rives.html

...I've read also that also impacts some media players, smart tvs etc that simply dont know how to handle the large drives.

While it the v1 may not support 3TB internal SATA, it may be worth searching for success stories of external 3TB being connected via USB.

I just connected my seagate external 3TB to my v1 duo (2xbay), looking under Volumes -> USB Storage Devices it came up with this:
USB_HDD_9 2794 GB No Filesystem 480

I could potentially format it as EXT3, but i'd need to investigate to see if would work before trying it out (i have all my data backed up on it, and not keen to wipe!).... keen to hear if anyone else has tried this?
