Putting 2x4TB in with 2x4TB on RAID 1
Hi there.
I have a ReadyNAS104 with 2 x 4TB disks in RAID 1 currently. I've purchased 2 more 4TB disks (same 7200rpm) and would like to know if I need to put 1 new disk in at a time or if I can just place both the new disks in, and should I be doing this whilst it is off or on?
Additionally can I just stick to RAID 1 or would I be better off putting the disks into RAID 10 along with the new disks, and if so how do I go about doing that if possible?
Doing some research I found these but wanted to be sure:

Never done this before so want to be sure of what I'm doing :)
Thanks and kind regards, Zippy

That would give you RAID-5, with a 12 TB (~10.9 TiB) volume with single redundancy. You'd just add the first new disk (hot inserting it), wait for the resync to complete, and then add the second new disk. Personally that's what I'd go with. Best practice is to back up your data before you begin, as if you have a disk failure during expansion you can lose your data.
If for some reason you want two RAID-1 volumes instead, then you first switch to flexraid. Go to the volume tab in the web ui. If you see a green stripe on the XRAID control then you are using XRAID. Click on the control, and it should switch to flexraid. Then hot-insert the two disks, select them in the center graphic, and create a second RAID-1 volume.
You can't get directly to RAID-10 unless you do a factory default - which would require you to set up the NAS again, and restore all your data from backup. I wouldn't go with RAID-10 myself - there isn't much performance benefit with an RN104, so I don't really see the point of it.

Thanks Stephen, much appreciated :)
Unfortunately last night I updated the NAS from 6.10.4 to 6.10.5 and now the admin web interface keeps kicking me out whenever I log in. I'm trying to setup an Amazon S3 bucket (using Backblaze B2) to backup my data first before putting new disks in. Anything I can do about this? Had a look around and there didn't seem to be a fix other than wipe the NAS OS which isn't an option for me. I can still access via SSH but the admin web interface was fine before I upgraded.
Is there anywhere where I can see known issues (other than the release notes) or that I can report this issue to Netgear?
Have managed to fix my Amazon S3 bucket access issue from https://help.backblaze.com/hc/en-us/articles/360047425453
"Note: If an Application Key is restricted to a bucket, the listAllBucketNames permission is required for compatibility with SDKs and integrations. The listAllBucketNames permission can be enabled upon creation in the web UI"
Recreated the application key and ticked the listAllBucketNames permission.
Useful documentation note: https://help.backblaze.com/hc/en-us/articles/360047779633-Configuring-the-AWS-CLI-for-use-with-B2
Next step I have to overcome is it turning red when selecting the existing Bucket as per https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Amazon-S3/td-p/1417022
I think the fix here was to use lowercase names for the buckets.
Still getting kicked out of the admin web interface though which is annoying!
Tried Chrome, Incognito Chrome, Edge and Firefox (can't access in IE due to SSL) and it happens on them all which indicates it's the NAS itself since this update.
