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/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
As we expected, we see very good write performance.
Read Transfer Rate
Here we see about a 200 MB/s improvement over a single 240GB 600 series drive.
A Seagate 600 series array can run with the best when writing data, but isn't in the same league as our Chronos and EVO arrays when reading data. A 600 Series array has nearly identical performance to an Extreme II array when transferring large chunks of data.
