I was a bit harsh about connecting to SATA drives. IDE has been
around for 21 years and ATA-133 is backwards compatible with 20MB
drives of that era, so I predict that you'll be able to plug SATA-1
drives into machines with SATA-9 interfaces.

But then, the motor might still not spin up... :(

No.

Enterprise tape drives are not "flavor of the month", and can always
read the previous one or two generations of tape.

And if you've switched from, for example, SuperDLT to LTO, then
you'll still be able to buy some drives on the used market (either
eBay or from a dealer).
