We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) of mostly incompressible random data as it's transferred from our OS array to our test drive/array. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive/array's read transfer rate. The system is restarted prior to the read test to clear any cached data, insuring an accurate test result.


Write Transfer Rate




Our data block is larger than our array's Turbo Write layer, and we can see that transfer rates are down somewhat due to the drive/array's write speed to capacity limitations.


Read Transfer Rate




Read Speed isn't reliant on acceleration, and our mSATA EVO array is able to deliver stunning performance, even slightly outperforming our larger capacity EVO array.




Our data transfer test is definitely where the rubber meets the road. We're transferring a huge chunk of random incompressible data. This is where everything we've seen so far comes together with actual data. It's easy to see the performance increase an array can deliver over a single drive.
