No, it isn't settled, annoyingly.

I have an 840 EVO, of course...

When I found out about the firmware issue I tested the drive and found that some static files had dropped to 100kbit/s rates. I've had floppy drives that were faster. I'd noticed that the machine was taking longer and longer to boot and this explained it nicely.

I did the firmware update, backed the thing up, and ran the fix tool, which restored the speed quite nicely. That was about three months ago, or so. A few days back, out of curiosity, I measured the speed again. It had dropped in exactly the same places to about 50MB/s, nowhere near as bad, but much slower than the 450MB/s+ speeds I get for most of the drive.

I ended up backing up again, rebooting in linux, zeroing the drive with dd, then putting everything bak, which got it running like the clappers again. Whether it will stay there is anyone's guess, though.

If the drive hadn't been free I'd be quite annoyed...
