We use AS SSD version 1.6.4237.30508 test to benchmark the speed of copying files within a single partition the size of the whole SSD. The SSDs are tested in their steady state.
The copying tests do not show us anything new. The three drives from Kingston do not have special firmware like the Intel 520 and cannot perform differently from other regular SandForce-based SSDs. As a result, they are inferior to the SSDs with Marvell and Everest 2 controllers at copying because the latter can ensure higher bandwidth for write operations.
