Not getting advertised IOPS (Samsung 850 EVO 250GB)

[Peso]

I recently picked up the 250GB 850 EVO and installed Windows 10 on it. I ran some tests on the drive to see if it's working properly and got good results in the Sequential Read and Write (540/506) but the IOPS was sub par compared to others with the same SSD. Originally I scored (48K/40K) in Read and Write and then I updated my AHCI driver to the latest AMD one and got (529/507) (56K/50K). I also ran AS SSD and got a score of 889 when I should be getting around 1100.

Motherboard: M5A97 LE R2.0 (Updated BIOS: 2701)
Firmware: EMT02B6Q
AHCI Mode: ON
SATA 3: Connected

Any help would be much appreciated I spent the entire day looking around the internet and couldn't find a solution.

installed Windows 10 on it.

There's your issue.

Window install bogs down SSD/HDD performance. If you want the "advertised" results, you need it to not have Windows install on it.

This. Benchmark results from manufacturers are done against a drive that has nothing on it - they're formatted and then benched.

Thanks for the replies but other users have reported getting the IOPS advertised after installing 2015 Intel drivers and running Windows 10.
