Hard disks store an error detection and correction code with the
data[1], and usually fail less subtly and regardless of the content of
the data. Whereas failure to motherboard, processor and power supply
tend to show themselves in very data-intensive scenarios such as
asymmetric cryptography. I think main memory less so, because the crypto
is likely completely contained in the cache.

HTH,

[1] Although if the embedded processor for instance would start failing,
it's possible to damage data with consistent checksums. Note that SATA
communication between disk and computer also includes a checksum.
