I deal with large data chunks and 40TB drives are an interesting idea.... until you consider one failing
raids and arrays for these large data sets still makes more sense then all the eggs in smaller baskets

This new 40TB hard drive from Seagate is just the beginning—50TB is coming fast!
(www.techradar.com)
The main issue I see is that the gulf between capacity and transfer speed is now so vast with mechanical drives that restoring the array after drive failure and replacement is unreasonably long. I feel like you'd need at least two parity drives, not just one, because letting the array be in a degraded state for multiple days while waiting for the data to finish copying back over would be an unacceptable risk.
I upgraded my 7 year old 4tb drives with 14tb drives (both setups raid1). A week later, one of the 14tb drives failed. It was a tense time waiting for a new drive and the 24 hours or so for resilvering. No issues since, but boy was that an experience. I've since added some automated backup processes.
I guess the idea is you'd still do that, but have more data in each array. It does raise the risk of losing a lot of data, but that can be mitigated by sensible RAID design and backups. And then you save power for the same amount of storage.

I can't wait to upgrade my NAS to a 200Tb Setup
cool 50tb. i can now download more stuff.
You thought 50TB was it? LOL! Hold on to your butts because 53.713TB SSDs are coming! These will cost you all your vital organs at 35years of age. Brains included.
I can't wait to lose even more data when this thing bricks
Ah yes. Seagate. The trash storage device company. If you want to burn your money, just throw it into a fire before buying this e-waste.
Can not recommend.
They're mechanical drives, every mechanical drive company has issues. I have had 4 of the 20tb drives in a truenas setup since last summer with zero issues. Drives in this size should be redundant and under warranty, expect drives to die, they're consumables. Replace, resilver, move on with life.

cool. now I can lose even more data when it dies.
no thanks...
…And it’s bound to be stupidly expensive.
Wish I could afford 20 of them, but not without winning the Powerball.
i don't mind that, if it means that lower capacity drives will get cheaper
