Ready nas 102 transfer speed

[PMDev]

I have a Readynas 102, is seems to be a bit slow, it’s fitted with 2 4tb iron wolf drives and has a 1000mbps connection. I’ve ran a test with nas performance tester and the speeds are
Write 37MB / Sec
Read 21MB /Sec

raid1 still on the initial re-sync?

$ tail -f /proc/mdstat

What firmware are you running?

Is the PC connected using gigabit ethernet?

[PMDev]

It’s not resyncing

Latest FW, computer has gigabit connection

If the data volume is very old, doing a factory default will speed it up.

Also, if ipv6 is enabled, then I suggest disabling it.

It’s about 2 years old. I’ve just disabled ipv6 but it didn’t help☹️

Still might help (depending on what firmware you were running when the volume was created).

It's been a while since I checked the speed (my RN102 is only used for some testing).  But I just took a look.  I'm getting 50-60 MB/s with NASTester 1.7, using a 400 MB file size.  Disabling strict sync increases the write speed to 70 MB/s, but of course doesn't affect read speeds.

The NAS is running 6.10.8 firmware, and is using XRAID (two 1 TB Seagate Ironwolf drives).  

File size definitely matters in these tests - with small files, the speeds are much slower.
