3-2-1 is the minimal consensus and not recommended anymore for everything you need to reliably have access to after a long time - the fact that some ransomware viruses intentionally have a very time they are laying low to decrypt old and rarely used files is one of the main reasons.
Healthcare, finance, taxation, accounting, etc. are all sectors that heavily rely on WORM media and long term tape storage.
You are right that a spinning disk often can work for 10 years - but there is a reason they are exchange earlier in a professional setting. Not all of them will.
And you were talking about cold storage disks. This is something even the manufacturers do not recommend - for a reason.
