Maybe has something to do with making assumptions about how the nand controller is going to allocate things across superpages but that is a stupid random guess and also I have no idea why it’s an OS issue but boy do they keep finding ways

I don’t understand. writing large amount of data at once breaks nand controller? and how that’s an os issue?

os updates write large amount of data to disk at once. especially a highly bloated os like modern windows. whatever the trigger, it’s still faulty nand controller. you can very well cooy a 20G file and see disk is corrupted.

That’s a good point on how the OS could be “causing” it. I don’t think my take was very likely after I thought about it for a while.

My assumption was it had something to do with the drivers for the controller, and the update flooding it faster than it could take data and not caching everything it couldn’t cram into controller DRAM, causing parts to just get dropped wholesale.

modern ssds have on board firmware that executes actual nvme (or sata) commands. so it’s possible a bad dma driver can coincide with a firmware bug to result in unexpected behaviour.
