Question Network / NAS Speed

[Scotch Egg 71]

Hi all

At home I have a server and a games pc, when transferring files from one to the other the speed is around 110 megabytes a second ( fairly decent ).

When I am at work the network speed there is about 10 - 11 megabytes a second, I know there are 10 of us but should it not allocate resources to whoever is using it?

Also the NAS drive is the same speed (it is a 10 bay with two 8tb drives in a mirror raid ) I would have thought that 10 say 4tb drives in a raid 10 would be better?

I know the IT firm also fitted a 10 gigabit switch.

How do I speed this up? is there a bottleneck somewhere of say a 10/100 switch or cable?

Any help would be appreciated.

Just to be sure:

You are asking about how to speed up the work network - correct? (And/or RAID NAS?)

If so, have those questions been asked of the IT firm?

HDD is slow compared to SSD, it's a rotational mechanical disk, the drive heads must seek and change tracks to arrive at the sector where files are recorded to do the read/write, it takes time.

8TB drives in RAID 1 mirror will not gain any speed from the setup.

Fast HDD drives sustained read write speed probably is about 200MB/s for a single user and a single large file.

With 10 people using the NAS and your PC likely with only gigabit port, even with 10Gbe switch, your PC's top speed will be 1gbps ~ 125MB if no one else using the NAS and only you are copying or writing the NAS with single file. If you are reading/writing a lot files, the speed can drop dramatically to only 1/10 of the top speed is not uncommon.

Although it can be many things those transfer rates are acting like you have some cable in the path running at 100mbps. If you were to see higher numbers like even 15mbytes you know that is above 100mbps so the port is likely running 1gbit. 12mbyte is about the maximum you will see on a 100mbps connection because of the overhead of things like mac addresses and headers.

First, is this your job. If there is an IT firm doing network work it probably isn't your job and management might not like you doing anything beyond submitting a trouble ticket.
BUT, it is most likely a 100Mbit network somewhere. I would troubleshoot by looking a the LEDs on the network switch. Are they all gigabit or higher ? If you see a port that is not at gigabit speed, then you can get the IT firm to investigate that.
