> HDDs are not designed for long term archive. They simply fail hard when being moved or switched off for a long time.
A single disk certainly is bad for long term archive. But when you have thousands of disks and use multiple copies for all data with some fancy error correction you can still get extremely high reliability, you just need to calculate in the expected failure rate.
