Another thing you need to check for is out-of-order writes. Sometimes the device will accept four 'write' commands, but obey commands 1 and 4 first, then 2, then 3, because commands 1 and 4 are for the same sector of storage. Sometimes it even does 1 and 4 in the same cycle. Sorry to say that this subject is one where the longer you spend looking at it the more annoying it gets. You either have storage devices which support ACID and transactions, or you don't.
