I think the results look okay (I tried it on my 840 Pro 256GB and get a bit lower results than on the one I posted), the drive tested there is empty as well.

I think the test Samsung provided uses average values as a results. The 96k is the maximum you can get in an ideal scenario (4K data and a queue depth of 32).
Thank you very much.

I feel better now, and just wanted to be sure I wasn't doing anything wrong when I set this thing up?

Thanks again for all of your help :toast:

IOPS is just another metric, you can use to measure transfer speeds:
IOPS x Transfer size in byte = bytes per second
Therefore if you are hitting the MB/s e.g. 540read and 250write, then the IOPS are correct.

Benchmark Scores Benchmarks aren't everything.
I've seen other 970 boards come up a little short on read/write speeds when it comes to SATA III. Is it possible that this is a limitation of the chipset and south bridge? Not all SATA controllers are created equal, including those included by the south bridge.
