There are situations though, where you’re working on a document and the documents “save” format is a memory dump. Corruption for things of that type (Adobe RAW for example) would remove data.
It might present itself as a 1pixel colour difference, but it could be more damaging (incorrect finances, in accounting software for example). Software trusts memory; but memory can lie.
Perhaps consumer-grade software that needs guarantees of correctness should be using error correction in software. For example, database records for financial software, DNS, e-mail addresses, etc.
Those corner cases might occur rarely but are probably inconsequential given rate of occurrence versus rate of criticalness - it probably doesn't justify the markup for most. In a data center you're processing millions of transactions per minute so occurrence is much more impactful.
