> Are any consumer drives affected by the same issue?

As far as I know it doesn't affect consumer drives, but I wouldn't be surprised if some have the same defective firmware.

Is there any information about the provenance of this SSD controller? Sounds like enterprisey venodrs all rebranded some upstream supplier's hardware.

edit: apparently sandisk: http://forum.hddguru.com/viewtopic.php?f=3&t=39964 - also a clue about the magic 40k hour significance: "the SSD alters its performance in some way as it approaches end of life. This appears to shine some light on the reason for a trigger at 40K Power On Hours."

This apparently also happened two years ago?
