The #wikipedia page on #RAID would need some love, really.

To explain for instance that #hardwareRAID used strategies such as inline #EDAC appended to oversized sectors (512b vs 520b) so that #DataIntegrity could be assured regardless of the reliability or lack thereof from a given drive & its firmware.

It's a lot more recent that these features were dropped for the ever-so-idiotic "more speed lol" reasons.

While it was standardized fairly late (https://en.wikipedia.org/wiki/Data_Integrity_Field), you can be quite certain that non-standardized enterprise RAID did similar things before that.
