Data Purge 0% Fill - The TRIM Test


With all of the data purged off the drive we see the 5.0.3 regain full performance and running within 2-3K points of FOB state. The 5.0.2 non-TRIM working FOB state starts out much higher, nearly 90K, but after a good work out, loses around 30% of its performance, until you clean the drive with a secure erase cycle.
