RN102 mixed drives
I'm trying to use two drives with different sizes (1TB and 5TB) and get some level of protection. According to https://kb.netgear.com/21387/What-is-the-volume-capacity-when-installing-disks-of-differ...

That article is accurate for Sparc ReadyNAS, the last of which was discontinued about 6 years ago now.

The whole article appears to be false. In XRAID, so long as you start with all 4 drives in their example, or at least include the smallest at the begining, you can use all of the capacity except when there are just two drives. With all four, there would be one 4x250GB layer and one 3x500GB layer, all as one volume. It is in FlexRAID that the smallest drive limits the size.
Maybe this was true for the legacy OSes? I never had a mix of drive sizes in mine.

Thank you for clarifying. That article certainly should have something about the specifics. Last updated timestamp is only a year ago, making it look even more trustworthy.

Applicability notes are an ommission in a lot of the KB articles. Perhaps Netgear expects people will go to them only when directed to do so, but that's certainly not true. They show up in web searches and folks expect them to be accurate for all systems when there is no indication otherwise, and even moreso when the date on them is recent.
Assuming the date means the last time the article was reviewed for accuracy, the person doing the review did not do a very good job.
