Well, that at least tells me that your disk is running fine, but I would expect higher writing speeds, depending on what kind of drive you're using!
So, what kind of drive is this you're writing to? Single 5400rpm or 7200rpm drive? Or...?

Samba can be CPU intensiv and prodcues high overhead compared to NFS or FTP (except that FTP has a problem with many small files due to how the protocl works).
However the speed should be way higher, than your 13MB/s or 20MB/s with FTP.
May some of the other mods have some more suggestions on what to check, as they has some more experience with running VMs than I have.
Greetings
David
Yeah, you should get higher speeds with OMV 
Greetings
David
If a different VM on the same machine (or even another protocol on the same VM) gets higher speeds? I doubt it.

True 
I haven't read everything but yes. Certain nics can have issues with some routers, switches or hubs (or sometimes even a bad cable). It can effect transfer rate. So if you are having problems with you OMV make sure you look into other possible causes. I personally had some issues with a Realtek NIC on my WHS-2011. Transfer speeds were slow going thru my gigabit routers switch to my OMV. I got a new HP switch and everything is plugged into it now and speeds are great.
... slap me in the face... I overread that you're using an RAID5 array... yeah, that's it what's slowing down your writing speed and that doubles up in case you write via SMB.
Please try to read files from your NAS via SMB and tell me the speed, if you can try read/write via NFS it would be nice to know what the speeds are there.

9MB/s read via SMB 
I was getting 15-20MB/s with FreeNAS on ZFS!
The CPU and RAM usage don't go up beyond 3% when reading either...
Thanks David
117MB/s via FTP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 
So what is wrong with my SMB 
Thanks again David
Try putting the following the Extra Options box on the main smb/cifs tab.
strict allocate = yes
45MB/s read
15MB/s write
An improvement considering, however couldn't I improve on this further on the basis FTP is reaching over 100MB/s?
Thanks for all your help
Samba has a lot more overhead in the protocol than ftp which will slow it down in a VM. I get 40 - 50 MB/s on my VM but 110 MB/s native. The write is slow though. Try the following command as root:
echo 8192 > /sys/block/md0/md/stripe_cache_size
You may have to change md0 to whatever your raid array is (ie md127).
Hello
I tried this, updated successfully however there was no benefit
Thanks for your help
Try a different virtual nic.

You should be using e1000 or e1000e.
