I’m not sure but i think I did a detailed video on it too showing the duobond chip or whatever its called.

I out an old toshiba in an elements enclosure. It’s easy to store and rhe usb interface is great!

Your comment helped me confirm it.

I’m in EU so prices are a bit higher here but the difference between the drive is relative anyway.

I’m probably going to get the 20tb.

I would do new PC instead of nas.

There are many MB with CPU integrated and pcie or lots of sata ports for either nvme or hdd/ssd.

Case can be old. But you want energy efficient components.

Some nas setups get expensive.
