Why would the (S)ATA standard not have a mechanism to verify that data has been written to the physical disk short of flushing the whole cache (or perhaps by disabling it for some writes...can't remember if that is SCSI or ATA which allows that)? Why not allow the computer to ask whether a particular write has been committed to permanent media?

To answer a question someone else asked: Yes, since the hard drive knows more than the kernel ever can about disk layout it is best to present a simple interface to the kernel but ATA/SCSI don't do it correctly. Ideally the disk interface would internally manage transactions. Moreover, it would be best if the kernel could communicate more information about the type of file access that is expected.


Instead, however, creating a safe filesystem (won't be corrupted by a crash) with optimal performance will likely require a fully asynchronous (as opposed to log based) commit mechanism. Done correctly it should be possible to have full transactions without ever issuing an flush to the disk hardware (if the transaction requires A and B for a commit one simply ignores that information unless both A and B are on the disk). Unfortunately doing this right seems really hard and may not even be worth it.

But why oh why can't disks just inform the kernel that some write has been committed to the physical media? Is this a market segmentation play to keep people who want better reliability paying for higher end interfaces/drives or what?
