   True for all drives, unfortunately.   
      
   It’s bloody stupid, because the drive caching is on the wrong side of the   
   drive interface. Better to leave it to the OS, which can use main RAM for   
   its filesystem caching, on the fast side of that drive interface.   
      
   When a drive says to the OS driver “write is done”, it should mean “write   
   has gone to actual persistent storage”, not “write is in my cache”.
