> $10 / TB

That's a remarkably good price. If I had $1.5k handy I'd be sorely tempted (even tho it's Seagate).

It's a good price but the Barracuda line isn't intended for NAS use so it's unclear how reliable they are. But it's still tempting to roll the dice given how expensive drive prices are right now.

I was tempted by 4 x 28TB (Recertified Seagate ST28000NM000C) but could not work out what I would use it for.

I've recently shucked some Seagate HAMR 26Tb drives hopefully they last

I won that lottery with 3x 26TB Exos shipped. I decided to try and get two more but they ended up being HAMR (returned). Then I managed to find two more earlier manufacturing dates in store stock at a somewhat-far Best Buy that I was driving past anyway.

It felt like an unnecessary purchase at the time (I'm still waiting to CAD a CPU cooler mounting solution for the build in a new case that has room for the drives). But it seems like that deal is going to be the high water mark for a few years, at least.
