Actually we are talking about the name of the SET FEATURES subcommands that has generally been called Enable/Disable Read Ahead.

I would agree there are many different implementations of Read (and Write Cache) but I think most people expect the SET FEATURE subcommands in question to enable/disable the Read (or Write) cache feature/function in the drive no matter what the actual cache implementation is.
