What is a good Speed for a NAS

Plermpel
 Share

Hello,

 

I just set up my "new" NAS with OMV, it runs on an i3-6100 with 16Gigs of RAM.

I have two 18TB Seagate SkyHawk HDDs in ZFS mirrored with compression enabled and the OS runs on an old Samsung 120GB SSD.

And I am currently copping all my stuff over there.

So what is a good speed for that kind of NAS?

With my big BD rips I get about 60 MB/s, is that allright, seems slow to me.

The i3 is on 5% usage and about 8GB of RAM used.

I was more expecting like, double the speed, should I disable the compression?

It should be fast enough to stream your media without issue. Everything else is wasted.

This is on a gigabit network right?

 

Try using something like crystal disk mark to test the seed?

 

What compression mode? Almost always compression will make it faster, and thta cpu can compress with most settings much faster than the hdds can read and write.

Which OS?

You should be able to saturate gigabit (~100MBps) with that setup. There seems to be a bottleneck in the network somewhere. What devices are in the chain between source and server?

 

Compression is essentially free, performance wise (the algorithms are well understood and very fast).

Yep, NAS is connected with two Gigabit NICs via bonding, but PC has only 1Gbit.

AFAIK CrystalDiskMark doesn't work on network storage.

IDK, the standart compression of ZFS file format.

Just an AVM Fritz!Box 7590 shouldn't be a problem everything wired with CAT7

Id turn off bonding, can cause issues, and won't help here

Yup it does, Ive done it many times. Need to run it as a non admin account.

Did try that, made no difference at all, bonding is set upp in balance-rr, just in case my with uses the NAS at the same time.

Did just try only wotrks on C and D drive.

Is the network share a mapped drive?

Did you run crystal disk mark as a admin? Make sure uac prompts are on, and you click no when it comes up.

Id keep it off and use smb multichannel for better speed + multithreading + redundancy.

Ok, did work, with the select folder option, after running it as Admin, weirdly

Then the nas seems to be. Probaably a limit of the other drive or the program your using to copy things.

How are you copying files? Try using robocopy with multiple threads.

Just tried that, makes no difference, also I build a NAS with pretty much the same config some time ago and he gets constant 112MB/s like it should be, with normal windows copy.
