Plenty of articles on the NET to try and assist, but still stuck around 40MB/s for my HDD.   I think people have said FTP is very quick, so will probably test FTP tonight to see if that's the case because running USB benchmarks on my rock64 show the speed maxes out.

The whole reason for me buying the rock64 was to try and get better copy speed across my LAN compared to my banana pi ultra m2.

Will try Bionic soon.

Nah... Samba is fine. You don't have to migrate to Bionic. Just try putting "noatime" option in your fstab and use EXT4 format instead. If you still don't get at least  70MB/s, check your Samba config file (/etc/samba/smb.conf).

Sadly reformatting to EXT4 and adding noatime didn't solve my issue, I was still getting poor performance. I've done some reading and noatime and it seem it would help on writes, but not much on reads (where I also have problems).

I did notice though that I was probably doing something probably pretty stupid...  Blush

I was under the impression that it was possible to dualboot with SCard / eMMC. All these test I've been doing was with the latest ayufan bionic setup installed on the eMMC.
To test If I was having these problems with other images I installed them on the SDCard and put on the jumper, but at some point I noticed that my kernel wasn't changing along with the images. Also uninstalling the newest kernel and reinstalling the older kernels gave me the newest one with uname -a (even though in the /boot/ directory I had the older kernel files). As you can see I'm still a but of a noob with linux Smile

So I've taken out the eMMC, reflashed the OMV version Luke suggested and things seem a lot better now.

Here's some testing I've done so far

That's more like it!

Write seem a bit low, anything I'm doing wrong with the parameters im feeding iozone?

Tested with Samba a bit and downloading from Rock64 hovers around 80 - 100MB/s, uploading seems to be about the same.
A lot better than my earlier results!

In case it my help someone, this is how OMV mounted the drive:
Code:
LABEL=boot /boot/efi vfat defaults 0 0
# >>> [openmediavault]
/dev/disk/by-id/ata-ST4000DM004-2CV104_ZFN0B7VM-part1 /srv/dev-disk-by-id-ata-ST4000DM004-2CV104_ZFN0B7VM-part1 ext4 defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl 0 2
# <<< [openmediavault]

and finally
Code:
root@rock64:/srv/dev-disk-by-id-ata-ST4000DM004-2CV104_ZFN0B7VM-part1/test# uname -a
Linux rock64 4.4.77-rockchip-ayufan-136 #1 SMP Thu Oct 12 09:14:48 UTC 2017 aarch64 GNU/Linux



Thanks everyone for helping, I'll probably stick with OMV since I really like the webUI
