Busy time
Note that lower is better in this benchmark. For some reason the DRAM-caching drive takes an inordinately long time to read data for the Photoshop test, something that is not shown up on the pure bandwidth results on the previous page or in the more basic Storage Test, and it seems like a problem of the DRAM and SSD cache not working harmoniously.
On the flipside, the standard M6e Black Edition's performance isn't great in the write test - it would be good if Plextor could combine the results of the two graphs into one drive.
