DiskBench - Directory Copy

We use DiskBench to time a 28.6GB block 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/arrays 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
Read Transfer Rate
When it comes to large data transfers RAID arrays are vastly superior to a single drive.
