The first question is, how slow is this storage?
Here is a good article on using fio:

Thanks for the help.
Here are the output of fio tests.
Single 4KiB random write process test:
WRITE: bw=197MiB/s (207MB/s), 197MiB/s-197MiB/s (207MB/s-207MB/s),
io=12.0GiB (12.9GB), run=62271-62271msec

16 parallel 64KiB random write processes (two different results, further
tests are closer to the second than the first):
WRITE: bw=523MiB/s (548MB/s), 31.8MiB/s-33.0MiB/s (33.4MB/s-35.6MB/s),
io=35.5GiB (38.1GB), run=63568-69533msec
WRITE: bw=201MiB/s (211MB/s), 11.9MiB/s-14.8MiB/s (12.5MB/s-15.5MB/s),
