Are you referring to the SSD command TRIM ? Additional info can be found in this MacRumors thread, and in the excellent AnandTech article linked to by the OP there.
Yes, that does seem to what I was referring to, but alas, even after reading the suggested links, I would hate to test on the issue, let alone explain it to others.
