Average transfer speed (read and write) plummeted after replacing hard drives

Good work on that article Retired_Member  :)

Hi EstivalG , I can confirm the 40MB/s transfer speed. I get that from my retired RN104 with two volumes (RAID0 and RAID1), which I'm using as a guineapig for trying things out.

I decided to benchmark my own RN102, and I discovered that my speed depends on the SMB protocol version.  I tweaked the the max protocol with SMBPlus, and tested the results with NasTester 1.7.  The measured read speeds are:

• SMB 1.0: 41 MB/sec
• SMB 2.1: 70 MB/sec
• SMB 3.1: 63 MB/sec

When I reported my 70 MB/sec results a couple of years back, I was still running Windows 7 (SMB 2.1) so the results haven't changed with newer firmware.

The drop off with SMB 3.1 isn't that surprising - I suspect Windows 10 is using transport encryption, and the RN102 has no hardware support for that.

The slow speed with SMB 1 was a bit surprising to me.

Test Details:

The RN102 is running 6.9.5, and the volume is XRAID (two 1 TB Ironwolf disks).  Bit-Rot protection (CoW) is off on the share; Volume Quota is enabled.   Strict sync is disabled, and SMB 3 transport encryption is set to "enabled".  Antivirus is off.   SMBPlus is the only app running on the NAS.

The PC is an older desktop running Windows 10; the PC is using 10 gigabit ethernet, but of course the NAS is using just gigabit.  The PC hardrive is an SSD.  

The NAStester results are:
