FIO 4k random read benchmark comparison

[SchumannFrequency]

READ score: 731 MB/s

Hardware: Intel 12600KF (stock) -- Kingston 6200 MHz CL36 -- Sapphire RX 7600 -- BIOSTAR B760MZ-E PRO -- Antec P6 -- Xilence XP550 -- ARCTIC i35 -- 980 PRO 500GB
Software: OpenBSD, bspwm, open-source GPU driver, UFS file system

test method:
fio --name=random-read --ioengine=psync --rw=randread --bs=4k --size=4g --numjobs=1 --iodepth=1 --runtime=60 --time_based --end_fsync=1

FIO (flexible IO tester) is the most common tool for benchmarking enterprise drives.
It is perhaps the most versatile and reliable tool for testing hard disk drive and solid-state drive devices.

It can perform just about any sort of IO generation one can think of.

Hardware: Intel 12600KF (stock) -- Kingston 6200 MHz CL36 -- Sapphire RX 7600 -- BIOSTAR B760MZ-E PRO -- Antec P6 -- Xilence XP550 -- ARCTIC i35 -- EVO 850 500GB
Software: Calculate Linux, KDE Plasma, Mesa open-source driver, XFS file system

Technical specs
EVO 850 500GB READ (random 4K, QD32) 94.000IOPS
980 PRO 500GB READ (random 4K, QD32) 800.000IOPS

The difference I measure in FIO is much larger than what I would think would be the difference based on the technical specs of the two SSDs.
The EVO 850 500GB has been in use for a long time and perhaps its performance has diminished over the years.
