Hello, Rusty,Looks like the read speeds on the nas side are decent, but also just guessing here, this is a transfer with multiple smaller files?
What happens if you try and transfer a single large file?
Are you using File Station to copy the data or some other method?
What model is the USB disk?
Hello, Rusty,Slow speeds I have to say (about half or less than half of what they should be), but there are a lot of devices in some cases. Also, how is your Macbook connected to your network? Is this wifi or ethernet?
Well, that's a whole different game then. That might very well be your choke point. It will depend on how well your wifi is working, what kind of wifi standard it is etc. So, if you have the option to connect your NAS and mac both via ethernet, that would give you much faster speeds for sure.Hello, Rusty,
The MacBook is connected to the network via WiFi.

Is your wifi AC standard? What router/wifi AP are we talking about here?
Guess that explains the speed then. 10MB/s max transfer.Hello, Rusty,
I enabled DHCP on my NAS and connected and connected the NAS directly to the MacBook via an ethernet cable.
I tested the download/upload speed. Surprisingly the speed went down. Here's the results.

When I checked the network interface on NAS, this is what I found.

What do you think?
Hello, Rusty,Ok so the mac is not the problem, but if you can see your NAS is registering a 100Mbit connection. That will not push more then 10MB/s. Replace the cable on the nas, check the port on the other end (switch/router) and see when the status of DSM lan will jump to 1000Mbit connection, then do your tests again.
The Network status you see if the NAS connectivity to your WIRED network. You've indicated several times that your Macbook is connected WIRELESSLY, which looks to be your bottleneck (as Rusty has tried to clarify). Have you tried connecting the Macbook to your router and disabled Wireless to retest transfer speeds?

Hello, CoffeeBlack,Basically...laptop disk* drives are capable of 125/MBytes (1000/mbits) per second for large file transfers (some a little more some a little less). Laptop SSDs are capable of up to about 8000/MBytes now (a little better then that but its a pretty niche market for those pcie4 nvme drives)...Wireless AC at its best can push just over 1000/mbits real world (more likely you'd be lucky to get 1/4 of that). Synology's nic's i think top out around max 40/gbit (most max are 1gb/1000mbit occasionally 10gbit). Mid tier to High end enterprise level disk setups like nutanix, netapp etc, will often have 10gbit or 40gbit or even 100gb nics or fiber connections (fiber = lower latency at the same speeds) etc (some ultra high end are higher still)...
In looking at that a little closer...8000 Megabytes...is about 64000 megabits. 40gbits is 40000 megabits. The Apple 2019's came with ssd's...And i'm going out on a limb here, but i'm going to guess its a pcie3 nvme drive...So probably around 3000MB/s (24000mbits) internally peaking thereabouts (this can range all over depending on load). If you had the best wireless router money could buy...you'd get maybe 125MB/s (1000mbit) [note i have a 2500mbit router connection from my pc to my router, and can't quite hit 1000mbit over wireless to the shared drive which is a 1TB pcie gen 3 nvme drive].
Point is...the limit is (almost) always the network. Also, wireless is much more finicky then wired. And...As others have mentioned, small files also slow things down if being sent 1 file at a time, as the disk spends a lot of time verifying and finalizing the file, and more often (causing basically pausing/latency during the transfer of several small files etc...its also often a more realistic load). If you used something that can make use of multiple threads (like robocopy if used/tested out properly), you can, sometimes, make better use of your network/disk setup. Adding in USB (3?) on your NAS, often the USB 3.x controllers on NAS's aren't always the top of the line, or* the CPU in your NAS isn't capable of sending as fast over the USB 3.x controller (as USB uses more CPU overhead then SATA and quickly reaches its limits).
I would start at the network...first, check to make sure you're connecting at 5ghz rather then the 2.4 ghz range, if you have neighbors, or if you live in an apartment, every single house/flat etc has at least 2 wireless 2.4 connections going on, and usually there's 8+. Multiply that times all of your neighbors, and suddenly your 2.4ghz connection gives you realistically about 15mbit (and may drop entirely for periods...while some joker is sending test data across wireless to his NAS...heh). If you can get a wired connection at gigabit+ speeds, that is 100% of the time, better over time, then any wireless connection you can currently get in a home (anybody who tells you differently is selling something or doesn't understand how it works...or both...for internal networks).
I need to routers to have 2 separate networks at home. One for family/personal and one for business.Why are 2 routers needed? And the last question - what protocol are you using to access the NAS from the Macbook? SMB? AFP?
