ATTO Disk Benchmark V.2.46
ATTO Disk Benchmark is the quickest and simplest method to determine transfer speeds and utilizes the same test methodology as manufacturers in arriving at performance results. It simply measures raw sequential transfer speeds for both read and write access at various transfer sizes, producing a very easily understood result.
Here we can see the controller using the maximum write speed that is possible for these drives. The C300 can write at 215 Mb/s, and these numbers show scaling above the maximum ‘stated spec’ sequential writes of the drives which is 1.720 Gb/s. Here we see results as high as 1.846! Also, how about that 2.775 max sequential?
We were pretty happy with this and could leave it alone but, well, we wanted to go just a bit further and see the speed of the DDR3. We decided on a few tests of ‘forced caching’ to highlight the speed of the new DDR3 cache that is used on the 9265-8i, the first controller utilizing DDR3.
Here you can see the results scale VERY nicely up to the size of the strip that we are using (64K). It would be very interesting to test the controller with the 1gb of cache to see just how well it would perform in caching scenarios!

If you want more detailed information on the testing, parameters and configurations used in testing, feel free to hit the forums! I will be happy to answer any questions, and as long as I have the hardware, if there is anything I have missed, I would be happy to run some tests for you and there will also be some more detailed presentations on 4k scaling for you enthusiasts out there 🙂 ~ Paul
