Slow transfer to Synology

[Thready]

I have 15 GB of photography to transfer to my Synology, and It shows it only going 2 MBps.

 

I use Cat6 cables, and both my Synology and my PC are wired to a gigabit network switch that is connected via cat6 to my main router. I get good download speeds on my PC, so the switch and router aren't the problem. 

 

I have no idea why the Synology is going to so slow. Any help?

what protocol are you using?

 

Wht is the usage on the synology?

 

What speeds do other files copy at?

I'm not that familiar with protocols, so I'm not sure. The CPU usage on the Syn is about 60% and this is a problem no matter what file. It doesn't matter if it's a lot of small files or one large upload. Here is a screenshot. It shot up to 12 MBps but this is a local network so that seems very slow.

Which exact NAS do you own and how exactly do you transfer the files? (Windows Explorer, FileZilla, Synology Drive, ...)

I use the DS 112j from 2013. I intend on replacing it this Christmas break. I just transfer the files by dragging them from Windows Explorer to the screen on Google Chrome. I interact with it via Google Chrome.

Long shot, but, you could be limited to the speeds of the drives in the NAS.

I use a 5400 WD Red.

It would probably be beneficial to use a SMB share instead.

You should at least give that a try and see if that changes anything.

 

Also which drive are you running? You should probably check the model number of that WD Red drive and make sure it's not an SMR drive. That could lead to lower performance.  You should avoid these drives:

 

 

And how is the read performance? After you set up a SMB share you could perform a speed test to see what the actual throughput is like.

Pretty sure this is your problem right here. A 5400 RPM drive is about as useful as that one 10,000 USD CPU Linus dropped.

That's not the issue. I run 5400 RPM WD Reds in my Synology NAS and I achieve up to 100MB/s write speeds. I usually average around 70MB/s.

I don't expect huge numbers here, but 12MB/s is rather slow for that drive, no matter how you look at it.

That surprises me. I've never had a 5400rpm drive that was even slightly useful. I always just use them for target practice whenever one lands on my workbench.

That's four WD Red 1TB 5400RPM drives in Raid 5 and a simple file transfer over SMB of a .zip file. (File size 947MB)

 

 

If I wanted to go faster, I'd first have to upgrade to at least 5Gbit networking to make it worth it.

But I'm also surprised. When I got the drives I was expecting around 50MB/s.

 

Edit:
And just in case someone thinks it could be because of the RAID 5.
This is the same test to my UnRaid box, which uses two WD Red 3TB drives. The bottleneck is the network here:

check that your not using 100m network conections, that 12.5mBit is about the same as the 100M limit

 

And yea use smb shares, the web browser is not the fast way to do it.

I thought that as well at first, but there's a spike in that graph that shows up to 15MB/s.

But I agree, it's a good idea to check the networking anyway.

IOPS take a dump when you're transferring lots of smaller files over SMB.

 

Test uploading with an ISO file or something large for a single continuous transfer.

Summarizing what was said before here but 15 GB (even of small files) should be much quicker over a gig connection with a NAS in RAID5, even if the drives would be dog slow individually.

 

From the sounds of it your networking is capable so use an SMB share and ensure both NIC's are negotiating the right connection speed (you should be able to statically set it for both devices if needed). If for any reason that isn't the issue the next thing I would look at is the read speed of your computer's hard drive.

NAS in RAID5

The Synology 112j is a single drive enclosure, so no RAID at all in his case.

If the drive supports it, you can enable write caching. Per the following link below

 

https://www.synology.com/en-global/knowledgebase/DSM/help/DSM/StorageManager/disk

Write Cache

Enabling the write cache support optimizes the system performance of your Synology NAS. Only certain HDD models support this feature. To ensure data protection while using write cache support, usage of a UPS device is strongly recommended. We also suggest you to shut down the system properly every time after use. Disabling the write cache will reduce the chances of data loss caused by abnormal power outages.

To enable write cache support:

Please follow the steps below to enable the write cache:

1. Go to the HDD/SSD tab.
2. Select a drive and click Action > Configure.
3. Tick Enable write cache and click Apply. By default, this function is enabled.

 

 

 

Also, make sure your Maximum SMB protocol is set to "SMB3", and the minimum is "SMB2 and Large MTU"

 

In theory, one or both of these changes should at least provide some improvement.
