Low disk latency on HDD, high latency on NVMe

Hello,

On a whim I measured disk latencies on my system with the command ioping -c 10 ., and on a BTRFS RAID0 array with two mechanical hard drives, LUKS encryption and FS compression I got this result:

4 KiB <<< . ( ): request=1 time=121.6 us (warmup)
4 KiB <<< . ( ): request=2 time=207.3 us
4 KiB <<< . ( ): request=3 time=165.4 us
4 KiB <<< . ( ): request=4 time=167.1 us
4 KiB <<< . ( ): request=5 time=412.9 us
4 KiB <<< . ( ): request=6 time=137.7 us
4 KiB <<< . ( ): request=7 time=146.5 us (fast)
4 KiB <<< . ( ): request=8 time=146.0 us (fast)
4 KiB <<< . ( ): request=9 time=187.6 us
4 KiB <<< . ( ): request=10 time=164.6 us

--- . ( ) ioping statistics ---
9 requests completed in 1.74 ms, 36 KiB read, 5.19 k iops, 20.3 MiB/s
generated 10 requests in 9.00 s, 40 KiB, 1 iops, 4.44 KiB/s
min/avg/max/mdev = 137.7 us / 192.8 us / 412.9 us / 80.4 us

And on a single NVMe drive (again with BTRFS, LUKS encryption and FS compression) I got this result:

4 KiB <<< . ( ): request=1 time=54.2 us (warmup)
4 KiB <<< . ( ): request=2 time=8.23 ms
4 KiB <<< . ( ): request=3 time=8.26 ms
4 KiB <<< . ( ): request=4 time=8.23 ms
4 KiB <<< . ( ): request=5 time=8.24 ms
4 KiB <<< . ( ): request=6 time=87.5 us
4 KiB <<< . ( ): request=7 time=8.23 ms (slow)
4 KiB <<< . ( ): request=8 time=8.23 ms (slow)
4 KiB <<< . ( ): request=9 time=8.24 ms (slow)
4 KiB <<< . ( ): request=10 time=8.27 ms (slow)

--- . ( ) ioping statistics ---
9 requests completed in 66.0 ms, 36 KiB read, 136 iops, 545.3 KiB/s
generated 10 requests in 9.01 s, 40 KiB, 1 iops, 4.44 KiB/s
min/avg/max/mdev = 87.5 us / 7.34 ms / 8.27 ms / 2.56 ms

So the average latencies for the HDD array and the NVMe drive are 0.19 ms 7.34 ms respectively. This is the opposite result of what I would have expected. Am I misinterpreting these results, or what?

Had a raid card or motherboard ?

I have an Asrock X570 Taichi motherboard, and if it does have a built-in RAID function, I have not enabled it. I also do not have a RAID accessory card.

Your results are much more in line with what I would expect to have seen from my single NVMe drive.

I had tested that ext4 is more faster than other fs !!!
try it and post your result :slight_smile:
