One thing I don't understand about Sandforce's throttling is how it determine how many years into the warranty the drive is. Does the SSD actually have a clock on board? If not, I guess it can only judge the passing of time by how many power-on hours it has had. In that case, the throttling could make a huge mistake for someone who only turned his drive on for 24 hours once a month, but ran Anvil's program for the entire 24 hours each month. After a few months, the drive would think it is only a few days old, but it has written so much that it would throttle the speed to try to extend its lifetime, even though what it has written is acceptable for several months of life.
