Which would not expected to be effected by the issue.  Crucial SATA
devices were already known to be uneffected.  Offerings sold under the
Micron brand might have exhibited the issue, but not Crucial SATA
(Crucial NVMe had mild issues).  Devices sold under the Samsung brand had
moderate to severe issues.  I suspect Intel flash devices would also have
been effected.

There was speculation as to whether systems with Intel IOMMUs would be
effected or not (alas you couldn't answer that).  Seems you got very
lucky this time.  I lucked out in not ignoring warning messages and
having backups.
