| Feb 12 at 15:16 | comment | added | Mikko Rantalainen | The problem is that sync cannot force the hardware to flush the cache. As explained in the answer by @msimic some specs allow unspecified time until the data is in permanent storage even after the device has reported OK after sync command. I would consider such storage drive firmware as broken but those are the specs that the OS has to use. | |
