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.

Yes, that's a good point, since I'm a home user, and downtime waiting for a new disk is fine. In the past, I've always had plenty of warning from the SMART checks, so I've been able to Advance RMA or otheriwse replace the dying disk while keeping the unit running. This is the first dead disk I've encountered.
So yeah, I'll go with single-disk redundancy. I suppose that's the default setting, but I guess I can save a few minutes by interrupting the 10-minute window and force the setup to start.
Thanks again. I'll mark this one solved :-)
