While this is true they are also optimizing for a wide range of operating environments. If you could reduce the size of the optimization space you could get a better result. There are many places where I could think of better behavior out of the disks, their current interface is somewhat limited and very much a black box. If you could open it up a little and maybe provide for some extra operations you could gain quite a bit.
For example, most RAID systems don't really care so much about the first error on the disk, if the disk fails to read we can save a lot of time by not retrying too much and just go to build from the RAID. If by any chance this is the second (RAID5) or third (RAID6) error than you want a much stronger retry logic. Current disk firmwares do not allow for such logic.
