one thing that is very noticable is that while the non-TRIM array scores like a mother clean 162,000 performance drops off further and faster as the drive is filled than the TRIM enabled array that only scores 135,000 clean. These are the same drives. The faster 162,000 performance was with 5.02 firmware that does not have functioning TRIM and the 135,000 performance was run on the same drives but using still unavailable to you guys 5.03 firmware that restores TRIM to the drive
