Tl;dr: Samsung's firmware says it supports NCQ queued TRIM but doesn't really. Windows doesn't support this feature yet but Linux does. Hence corruption. Patch is there in latest Linux kernel to work around this by blacklisting the feature from some Samsung drives.

Sadly still a disaster waiting to happen if a user running a not-bleeding-edge kernel sans blacklist decides to update their firmware... blacklist will need to be backported to all those kernels out in the wild that already support queued trim.
