Is there anyway to tell if I am getting the max speed out of my SSD? I have a feeling it's not. I double checked, I installed the nvme drivers, have the latest firmware. I have drive indexing turned off. I ran the Magician benchmark utility and for the result this is what I got:

Sequential (MB/s) Read: 2,791 Write: 1,934
Random(IOPS) Read:338,080 Write: 338,892

 

 

Can anyone check to see if its normal?

Looks quite normal.

 

Remember that different settings give different results.

I know the read and write for this are intended to be 3,500MB/2,100 MB/S. I want to try to get the most speed as possible . Can it be possible the CPU is bottlenecking the SSD ? Or something in Windows or BIOS i need to change?

 

My motherboard, Gigabyte GA-X99-Ultra gaming. I know it supports nvme:

CrystalDiskMark5 will likely give you the best case numbers (i.e. the sorts of best case numbers claimed for advertising), as it does indeed show 3200+ MB/sec on the sequential reads for the 960 EVO....

I know i'm probably asking for too much, but I still think that score could be improved a little bit. I seen some people who've had a higher score than I do, and my hardware is really good. Can there be something else I'm missing?

If you go to look at reviews at Amazon and Newegg you will see customers who are posting photos and showing their CrystalDiskMark results.

 

But if there is nothing else to change , then that's fine.

Most I saw had some test type results higher than yours while others lower. For example, they might have higher "Seq Q32T1" results, but lower "4K Q32T1". There was only one that had higher results than you in all categories. Generally, even if they were higher, they were generally no more than 10% higher and frequently not even that much.

It is likely a function of different motherboards, processors, and other hardware as well as how much you have stored on the drive potentially. I would assume the test settings (i.e. test count and test size) could affect things (while most used the same settings as you, some did not).

So, there is a good chance you are now to the point of "splitting hairs" as the saying goes.

As smax013 said, there is nothing really wrong. If you re-run that benchmark you get slightly different results each time.

So I suggest you accept that your drive is as fast it can be and even if it's not, few percent hardly makes any difference :)

Possibly the benchmark itself was tweaked over the past few months; my 960 EVO results a couple months ago were 3240 MB/sec, but, now getting just 3040 MB/sec, sequential reads...
