Looking at modern hard disks, I'm unconvinced we
could even mass-
produce
something like that today.
A 40mm radius is comparable to a 3.5" disk, which are generally 5,400-
7,200
RPM. 15,000 RPM is the fastest available, but those tend to be low-
capacity and
expensive, and are often 2.5" drives with a huge heatsink.
I am not sure if that hold true. 15K drives have been around at least for 20
years (unless you are considering that part of today?). I was using Seagate
Cheetah SCSI drives in 9Gb and 18Gb capacities w/ 3.5" platters spinning at
15K RPM back in the 2000s.
They may not be terabyte HDD but 15K RPM was definitely not an issue.
