Drive Upgrade from 1TB to 2TB

Personally I would choose a different drive.

Whichever drive you choose if the NAS will store the primary copy of any data that is important to you then regular backups of the NAS are important.

Welcome to the forum!

I'm not a fan of the Seagate DM drives in ReadyNAS. There are several people here who have had trouble with them. I'd go with the WD20EFRX instead (even though they are not on the HCL they will work well in the duo). Since you no longer have warranty support, there isn't a strong benefit to sticking with the aging HCL.

Upgrade your firmware first.

If you don't have 4K sector alignment you might want to do a factory reset. It's not strictly needed, but it will improve performance a bit.

Thank you both for the quick responses. I did see many recent reviews on the Seagate that were awful and that was enough to make me question if there were better options available. The WD20EFRX looks good; I'll look at it in more detail. Will also review the article you provided, StephenB.
Now, how do I know if I have 4K sector alignment?

Read the article I linked in above - the procedure is in there.

I bought two WD30EFRX (3TB) to replace the 1TB drives. I have a good backup of my ReadyNAS data and am ready to proceed with replacing the drives. Is the following a good approach?

Upgrade to latest version of RAIDiator
Do a config backup
Remove both 1TB drives
Install both 3TB drives
Perform factory reset per instructions on link you provided above
Restore Config backup

* Can I then put one of the 1TB drives in bay 1 and let it sync to the new 3TB drive in bay 2 to restore the data? After it syncs, move the 3TB drive from bay 2 to bay 1, install the second new 3TB drive in bay 2 and let it sync?

If ever that your RND2110 is a ReadyNAS Duo v1, I believe 3TB drives are not supported as per the HCL. Since I do not own a ReadyNAS Duo v1, I could say that it may or may not work.

For vertical expansion, I would suggest to pull-out disk1 then insert the new drive then let it resync. After the resync process has completed, pull-out disk2 then insert the other new disk then let it resync again.

Is the 2110 a v1 duo or v2 duo?

What firmware is on it now?
You can't use drives larger than 2 tb in a duo v1.

Of you have a v2 then....

Yes that procedure is good. You must power down before removing the 1 tb drives and inserting the 3 tb drives of course.
If you have any addons installed, install the, before restoring the config.

Your last question is worrying me.
Firstly you cannot do that, it will not work.
Secondly, where is your backup? It should be on a separate device.

You can retain the 2 disks that are currently in the duo as a secondary backup in case something goes wrong. In this event you could power down, reinsert BOTH of the 1 tb disks and boot up. This should take you back to the original setup. Remember to label the original disks according to slot number.

Thank you for the response Ixa. My ReadyNAS has been out of warranty for quite some time and I know the drives I purchased are not on the HCL. I'm hoping to also get feedback from StephenB who responded to my previous posts, to confirm I'm following the steps needed to include a factory reset so my new drives are formatted with 4k sector partitions; and to confirm my steps to restore/sync data are accurate.

I have the duo v1 running RAIDiator 4.1.14. I went up to the 3TB drives since they weren't much more than the 2TB. Sounds like I'll be returning them to exchange for 2TB.
My backup is on an external hard drive.

Yes, 2TB disks are the way to go with the v1.

3TB drives will be recognised with <1TB capacity in the Duo (v1). They are not supported in the Duo (v1) as the Duo (v1) does not support GPT partitioning.
