I run performance test for the NVMe device ( intel nvme 750 400GB ssd) on my intel i5-6600k desktop by using FIO. I found the result of the test is higher than the official.
The performance is as follows.
seq read : 2700MB/s seq write: 930MB/s
rand read: 690000 IOPS rand write: 230000 IOPS
Does it correct? It is stable every time.
Thanks for posting your question in the Intel® SSD community.
The performance information that is shown in https://ark.intel.com/products/series/79678/Intel-SSD-750-Series is an average of the tested SSDs following a specific test procedure under specific circumstances. If you want to see the procedure you can find it in the following link:
As this is an average there are some SSDs that will have a performance just on the limit and some other that will have a performance over the average as your SSD.
Also as you are using Linux this will generate a better performance because of the driver speeds of Linux. The speed that is shown in the performance website is for Windows.
Hope this helps to clarify your question.
