any benefit to factory reset after firmware update?
I just got a used Ultra 6. I did a factory reset, which finished overnight. Turns out it was on 4.2.21. The Ultra found 4.2.27 on Netgear's server and prompted me to upgrade. That is in progress ...

Since your backups need to be able to ensure data safety even if the NAS totally fails, the main value of RAID is (in my view) to optimize availabililty. That is to keep the files available during disk replacements and expansion.
Since I am a home user, losing access to my data for a short while is usually an inconvenience (not something that costs me money). So I am fine with single redundancy on the NAS.
If I ran a business, then I'd either go with RAID-6, or I'd have a second NAS on premise - which could serve as both a backup of the data and a hot spare.
If you chose to go w/o adequate backups (a bad idea in my view), then maximize your RAID protection with RAID-6.

Nevermind. Since the disk is dead; confirmed by switch slots; still dead in new slot; at least it's the disk and not the device/slot... doing a factory reset with 4.2.27 now. Disk should be under warranty (WD Red made in APR 2013).

Thanks. That would come in handy in a scenario where I couldn't switch disks around (i.e., there is data on the volume). I considered using WD's tool, but that would involve putting it in a PC, installing the software, etc. I just wanted to RMA it as quickly as possible.
Since it is still under warranty, I called WD's "Red" number (normal warranty # disconnected me after 20 min. on hold; nice), and got the nice rep to do an Advance RMA (WD's silly website would not let me select that option). He said they'd ship it UPS Ground, but they used 2nd Day Air, so I'll get it tomorrow. I'll slap it in there and boot immediately into the boot menu to do another factory reset. 4.2.27 is now on there, so it'll be as up to date as possible. The only question I need to answer for myself is single- or dual-disk redundancy. This episode now has me leaning toward the latter. I was greedy during the first reset and did not select that option. I guess I can live without that extra 2.7+ TiB of storage space, and will settle for peace of mind.

Hello ThurstonX,
That is RAID 6 and it is best choice for keeping the data in case of disk failures. The total capacity of your storage system equals the capacity of all your disks minus the capacity of two disks.
We strongly recommend to always have full back, though.
Regards,
