X-Bit Labs File Copy Test is a real world benchmark used to measure the performance of IDE subsystems. In this test, we time how long it takes to copy the Company of Heroes demo file (1.75GB) in various setups with File Copy Test program optimizations disabled to help provide the most accurate time possible.
Now we're at our last stop in our benchmarks and we check out real-world performance using a file copy test program.
As you can see from the first graph, the HPT controller is miles ahead of the pack being able to copy a 1.75GB game demo file internally (same drive transfer) in RAID 0 in just 29.7 seconds - almost 30% quicker than the Jmicron controller. This test demonstrates simultaneous read and write speed performance of the controller and as a result is an important test, since it is very intensive on the controller and drive.
When we copy from the test drives to master (demonstrating controller read speed), the results are much closer but the RocketRAID 2340 manages to come out ahead, once again, in RAID 0, but a little slower than the Intel ICH8R in non-RAID setup.
When we copy from master (non-RAID, single drive and demonstrating controller write speed) to our test drives, we are limited by the master drive's maximum transfer speed (in this case, 78MB/s) and that is clearly kicking in here.
Unless you have multiple performance type RAID arrays inside your system, you're not going to notice much benefit in a performance RAID array when moving data around (in the instances where you copy from a non-RAID partition to a RAID partition). While the RocketRAID controller can write data at an average speed of almost 150MB/s, it's only being sent the data at a pure maximum sustained transfer rate of 78MB/s from our single test master drive. The average write speed is in fact closer to 74MB/s, in the case of the single Seagate 7200.10 16MB cache drive, which we used for testing in this review.
