Readynas Duo (Firmware 4.1.16) Maximum Drive Capacity
Good Afternoon.
I'm almosts at Capacity on the single drive installed in my Readynas, and Am looking to upgrade.
I'm not certain of the model, but the Firmware is 4.1.16 if this helps.
What is the largest drive i can install? I'd like to install 2, and assume that by doing so, I'll have one lot of storage, but duplicated incase of drive failure, is this correct?
Eg: If i buy 2 x 2TB Drives, I'll only have 2TB of Storage but it'll be 'safe' as it were?
If this is the case, How do i go about setting them up in this manner, or is this an automatic process?
How can I tell what drives are compatible? I have my Eye on 2x Toshiba Drives.
I do apologise if this has been covered, I'm a little new to Readynas and though I've had a search, I can't appear to find what I'm looking for!
Thanks in advance
David
As long as you have not disabled XRAID, the process is automatic. Insert one of the new 2TB drives (that is the largest your unit will accept) into the empty bay and let it sync. Then remove the original and let it sync again. Do these with power on. You will then have 2TB of redundant space with your original data still on it. Note, that I did not say safe. Your NAS is very dated. Things other than drive failure can and do happen, and you can lose your data even on a much newer NAS. A safer way is to connect the second drive via USB using a format your computer can read if the NAS fails (NTFS for Windows users) and use backup jobs to copy the data. It's still not safe from fire, flood, theft, etc., and it's not automatic, but it's safe against a NAS failure. RAID provides for continuous access to the data through a drive failure, but is not a backup system.

Thankyou for a Very informative reply.
Is there a USB Drive that you would recommend?
Thankyou.

On the USB drive, you'll get faster backup speeds if you attach the backup drive to a PC and back up over ethernet. The 4.1.x systems are extremely slow at USB backup (particularly to NTFS drives). That also allows you to use any size USB drive - the NAS is limited to 2 TB on external drives.
