DiskBench - Directory Copy

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, in order 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
A 493 MB/s write transfer rate for a 128GB total capacity array is so good, it's almost unbelievable.
Read Transfer Rate
LSI SandForce controlled drives have awesome read transfer performance.
This test is definitely where the rubber meets the road. This is a huge chunk of random incompressible data we're transferring. SLC clearly shows superior performance in this test. Despite being severely capacity handicapped, our SLC powered SuperSSpeed array has way better write performance than the Chronos array, even though they are both powered by the exact same LSI SandForce 2281 controller.
