Looks like a great deal on a cost per GB basis. And B&H is a reputable e-tailer. Not sure why it got a downvote. No tax if you use their store credit card (Payboo) as well!

Needs to be at $330 to compete at $15/TB like the 14-20tb models.

Show me a 20 TB today Pro or Exos going for $15/tb which equates to $300 brand new and not gray market. Right now they are more expensive than this 22TB. Also the top end drives always go for more than mainstream drives because they are the top end. So you can't equate the per TB cost of a 12 TB with a 22TB.

At current prices 22TB drives are pretty close to smaller drives like 18TB ($16.7/TB) vs 22TB ($17.5/TB) , but on sale its not so close.
You'll have to decide if you want to pay more for top end or wait for deal on near top of the line. Deals come and go. 18tb was $14.5/TB just a week ago. 20tb externals where less than $15tb last week and regular pros go on sale once a month or so. If you must have 22tb ok then, otherwise I rather buy 5 18tb drives instead of 4 22tb drives and have 54TB Raidz2 vs 44tb. Or wait a little bit and get 6 18tb drives and have 72tb of raidz2 storage. If you can swing it go with 5 22tb drives for $1900.
I use 12TB of data a year and keep systems for 6 years, about 72TB, so 7 18TB drives in RaidZ2 works for me and saves me $500 or so when on sale, and $200 at higher prices. It depends on how much data someone needs, NAS/Server space and plan for the use of the space/drives. If I was limited in the number of drives I could deploy and had a need for a certain TB amount, larger drives make more sense even if they cost more.

I think the sweet spot is 12tb right now but I started buying 14TB to replace my aging 8TB which are around 7-8 years old now. Since I use Unraid I normally put the largest drive in first as parity and then use the old drives as secondary backup until they give up the ghost. Since I spin them down when not in use its just a matter of drive slots which I have 10 so YMMV.
I also don't buy new anymore get recert it is much more cost effective and I backup at least 2 copies of important data but I understand some want new.
