DC P4500 Wrong IOPS Numbers?

ATakc — Sat, 17 Feb 2018 10:28:27 GMT

Hello,

We have purchased 42 Intel DC P4500 4TB NVME drives from a vendor ( Sn : SSDPE2KX040T7) . Before making the purchase we have calculated our Read/Write IOPS requirements and have checked your website about the specs of this drive. I am pretty sure that write IOPS for this drive was 62000 IOPS which is enough for our needs and we have made the purchase last week ( havent received the drives yet) . Yesterday I have checked the specs page again and see that write IOPS has been changed and lowered to 48000 IOPS!! May I ask what is going on here? 62k iops is enough for my workload but 48k iops is not.

You have given wrong numbers on this drives specs and i am having big trouble in here.

Please guide me how to proceed with this purchase. Can i return these drives and change into more write intensive drive like P4510 ??

The web page we have checked was :

https://www.intel.com/content/www/us/en/products/memory-storage/solid-state-drives/data-center-ssds/dc-p4500-series/dc-p4500-4tb-2-5inch-3d1.html Intel® SSD DC P4500 Series (4.0TB, 2.5in PCIe 3.1 x4, 3D1, TLC)

And here is the August version of that web site:

And here is the old anandtech article shows the write iops of the drive to 62000 iops.
