There was some widely circulated study few years ago which found that most SSD models they tested had problems on power loss. Some even bricked. They didn't publish concrete names, unfortunately.

But yeah, I agree it's a bug and shouldn't happen. So what :)

Note that the 320 recommended by the second article had similar issues, supposedly fixed in firmware 4PC10362, but some users reported problems even on that version: https://communities.intel.com/thread/24339?start=15 (many of those complaints look like different problems, but not all).

I had corruption issues with an OCZ drive on a machine with unstable power. Since adding a UPS the drive has been rock solid.

We had corruption / sudden death issues with OCZ even on machines with redundant power supplies. I do not recommend them.

My "favorite" were the OCZ Vertex 1 drives which almost certainly had issues with the firmware eating paste and overwriting some internal metadata - periodically the drives would start throwing read/write errors on swathes of LBAs, and the only way to mitigate this would be to throw the jumper on to put the drive in "recovery" mode and do a destructive firmware reflash that blew away all the contents.

And then it would work perfectly well again...for a while.
