Mechanical disk drive platters have always possessed a ferrous film (Iron oxide--rust) coating layer which is the magnetic recording surface. If you look at the old 12" drives the platters are red because back then they literally used iron oxide as the platter coating. Today platters are a shiny chrome color because the coatings contain other elements as well and the coating is much more dense. Before SSDs one could say "HDD" and everyone knew what this meant. Today "HDD" can mean either mechanical hard disk drive or SSD. To easily differentiate, it has become commonplace to refer to mechanical hard drives simply as "rust" because it's quicker to type and universally understood. If this is the first time you're seeing this term that's a bit surprising. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
