> As long as other properties weren't violated (eg. ordering), your data should mostly be okay, aside from that 1s of data.
That's the thing though—ordering isn't guaranteed as far as I remember. If you want ordering you do syncs/flushes, and if the drive isn't respecting those, then ordering is out of the window. That means FS corruption and such. Not good.
The tweet only mentioned data loss when you yanked the power cable. That doesn't say anything about whether the ordering is preserved. It's possible to have a drive that lies about data written to persistent storage, but still keeps the writes in order.
