It is one thing to talk about high sequential numbers and it is something else to see them compared to a group of the fastest solid state drives on the market. When I finally looked at the chart I called Cameron over to see it. At the same time, we both smiled and then started laughing to the point where it was uncontrollable. So yeah, pretty much the same thing you are doing right now.

As I stated before, the drive being tested today has been hit pretty hard prior to testing with just about every kind of benchmark you can think of. The minimum write speed was at the beginning of the test and the results were typical for a drive that has been ran hard during testing (one of the reasons why you don't want to pound your drive with benchmarks, just read about them here).


So, with in a fraction of a second of around 165MB/s, the A-DATA S501 quickly reached the average speed of around 207MB/s and peaked at 211. These are not quite SandForce SF-1200 MP1 speeds, but they are getting pretty close.


The other Marvell controlled drive on the chart is also the only other SATA 6G interface drive. Here we see the Crucial RealSSD C300 128GB drive running into its wall at just under 140MB/s. It looks like A-DATA and Marvell have found a way to get around that little issue with this controller.
