Since Sandforce often has "extra overprovisioning" due to the data compression, this simply allows it to function that much more efficiently.
But the chance of that happening would be remote and if the drive was full you would only be reading from it anyway. Let’s say your drive is 80% full. How much of that 80% is actually written data? 40%? 60%?

“What we saw was a dramatic reduction in performance”.

“………..The takeaway? While SandForce’s controllers aren’t immune to performance degradation over time, we’re still talking about speeds over 100MB/s even in the worst case scenario and with TRIM the drive bounces back immediately.”

Still good performance even in a worst case scenario, I guess the issue is that mileage can vary.
