Question Seagate Firecuda 530 poor performance on Linux ?

[andi77]

Hi @All,

I am facing strage benchmark values on the Firecuda 530 NVMe's when running in Linux (Debian 11, Arch, Ubuntu, etc.) with fio benchmark test.

fio --time_based --runtime=60 --size=50G --rw=randwrite --name=benchmark --bs=4K --direct=1 --sync=1 --filename=/mnt/test.file --numjobs=16 --ioengine=libaio --iodepth=128 --refill_buffers --group_reporting

Which results in:
/dev/nvme0n1 Seagate FireCuda 530 ZP1000GM30013 4K randwrite write: IOPS=3292, BW=12.9MiB/s (13.5MB/s)(3893MiB/301383msec); 0 zone resets


On Windows 10 testing with CrytalDiskMark everything seems fine.

Does anyone else have the possiblity to test and confirm me the benchmarks ? Also some kind of solution would be nice, as I do really not kown why this performs so bad on Linux.

You can't directly compare the results obtained via 2 different tools. Your best bet is to compile fio on both machines, using the same compiler and options. Then, and only then are the results comparable.

Well of course it would be better to use always fio. But with Windows, fio is kind of not so good to use.
The machine is always the same but with different Operating System only.

And I did also the exactly same fio Linux test on the same machine with a Samsung SSD PM9A3 and that one perfroms at it should (almost the same results in LInux as in Windows with Crystal Disk Mark).

So it is defenetivly the Seagate Firecuda 530 which performs very bad on Linux and it has nothing to do with the Benchmark test itself.

BTW: An important fact is, that only the Random Writes are bad. Sequential Wirtes and Random/Sequential Reads are in Linux good too.
