If you connect that drive back to the NAS, do you see the files? If you can, then the drive was probably formatted to a file system that your iMac can't read.

Is there any reason they won’t work after that amount of time?

Your first problem isn't how long these drives will work but how to check if they still work 50 years from now. Do you think computers in 2073 will still have the connectors being used today (e.g. M.2, SATA, SAS, U.2, U.3, EDSFF, etc)?

Take PATA HDDs for example. That storage interface began disappearing from motherboards in 2007. HDDs using that interface stopped production about 10 years ago. As years go by, even adaptors for that interface will become rarer. If you asked this question 20 years ago but instead of SSDs you stored new PATA HDDs, do you think you'll be able to check if they're still working 30 years from now?

To workaround the connector problem, you'll also have to store equipment that will work with the interface for those SSDs. Maybe a motherboard, an adaptor, even a power supply. How long would those extra hardware you have to store will last?

The PM987 would have a 21.024 PBW endurance rating compared to the 2.4 PBW of the 990 Pro. Not sure if it has PLP though but it looks like it has the capacitors for that feature based on the pic from TPU.

High wattage 19.5V 7.4mm are usually harder to find. Most common are 65W chargers.

HP uses two different voltages for the 7.4mm black tipped chargers: 19V and 19.5V. Not sure if both will work with the latest gen mini PCs but 19V chargers will work for these. I've had a hard time looking for 120W 19.5W chargers that 705 G1 minis used that I had to resorted to using 19V ones.

Their laptops use the smaller 4.5mm blue tipped chargers. Makes sense since these laptops are too thin.

I'd just get a good internal nvme drive and put it in an enclosure.

Xcode has an iOS simulator. You can have a macOS VM run xcode.

I have an extensive config inclduing vlans, plugins, policies, suricata, VPN, routes, gateways, HAProxy, etc.

When you have an extensive config, you should always test the upgrade on a "lab" machine before applying them to your "production" environment. You don't just apply the update blindly and hope nothing breaks.

I use RapidCRC.

Use PAR files like the others suggested.

Or use WinRAR's recovery volumes.
