A Kingston DC1000B 480GB NVME SSD can do 11400 write IOPS

This is much better than the Samsung 980 NVME SSD. The settings i used.

fio --filename=/dev/nvme0n1 --direct=1 --rw=write --bs=4k --ioengine=libaio --iodepth=1 --runtime=10 --numjobs=1 --time_based --group_reporting --name=iops-test-job --sync=1
