Well, when people are shocked that someone is experiencing 1-4 single bit errors a month across an expanse of 48GB, it's not hard to see why people think it's not something they need.
A single bit error is enough to create a misspelling in a txt file. There's a low probability of it happening, but if it does, it's unnerving to think that it will not be detected.
- In consumer equipment, much of your RAM is often unused at any given time
- Most lines in a cache are eventually thrown away, never used
- Did you even save your text file, or just open it to read it?
- What about all the space occupied by read-only information, like executables, media files, game files, and libraries? You might crash, but nothing will be written to disk
You might get an error a month, but the odds you'll get an error that matters on your average consumer machine with average workloads is much much lower.
