Thanks Mike!
Pasting new results for loaned machine and things are getting more
interesting (with respect to Marian's reply):
single (rotational) device:

single PCIe SSD device:
(Staring to immense difference between sequential reads and random
reads. Can it be there some sort of raid inside SSD card?)

4 rotational devices forming md raid5, 512KiB chunk size:
(I'll repeat this one since there's strange increase in random read
performance on raw raid5 device, see line "disk_nocrypt-randread"):

Now I would like to work on simulating different workloads (these tests
were simulating 4 jobs in fio on otherwise idling machine)
