Asrock Q1900-ITX/Q1900DC-ITX


Recommended Posts

i have between 90 and 110 mb/s per second from windows 8.1 over gigabit lan, from disk to disk.

 

I tried again, Win8.1 says 35/40MB/s and it's not stable at all!! I don't know which is the problem.

 

Here is my config

 

Q1900-ITX + 4GB Ram

WD RED 3TB (1 disk at the moment without raid)

Nanoboot-5.0.3.2 DSM 5.0-4528 X64 Update 1

 

Any suggestions? Have someone else the same config? I'm thinking to re-install everything again.

I have a constant 120MB/s transfer on big files@HyperV

Which Server you have? Hyper-V Server or 2012 Server with Hyper-V? I tried on a virtual machine the Hyper-V Server (the free one) but it's very hard to configure! Can you give me some tips?

Well, then that's the max speed that drive can have and the speed degrades so much at a certain moment in time because the buffer is getting filled up

Have you tried other ethernet cables?

What kind of cables are you using? Cat5/Cat5e/Cat6?

Are your devices connected to a 1Gbit switch or a router with 1Gbit switch? Are they connected to the same switch?

Have you tried copying to another pc?

Are your devices grounded?

:smile:

Yes i changed the cables and both are cat.5e.

I also tried on a newer laptop and it was about 20MB/a more, so I reached about 65MB/s.

 

Both of them were connected to a gigabit router.

 

I'm not so expert but I think it could even depend from the xpe driver, that's why I would try with hyper-v, maybe the network adapter is better supported on win server.

I don't know which HDD is in your laptop, but that disk could also be your bottleneck and not your NAS. Is the disk in the laptop fragmented? If it is, then that for sure could degrade the performance of your disk.

Have you tried copying between the 2 laptops?

DUDE,

65MB/s for a SATA disk is THE limit. You won't get faster unless you have a RAID matrix.

Cheer up and don't change your config due to performance. It's working fine just with 1 drive.

Sorry, but that is simply not true. My N54L came with a 250GB SATA drive on which I have installed Xpenology. With that ONE disk I am able to read/write with FULL 1Gbit speed = +100MByte/s.

A normal 3½" 7200rpm SATA drive is able to deliver approx 120-130MByte/s on the outer tracks, and approx 80-90MByte/s from the inner tracks.

 

I have no experience with 2½" drives, so I don't know the transferspeed they may be able to deliver.

 

This command times how long it takes to write 1GB to volume1:

time dd if=/dev/zero of=/volume1/bigfile bs=64k count=16384

 

And this how long it takes to read 1GB from volume1:

time dd if=/volume1/bigfile of=/dev/null

 

These commands have to be run from a shell on the NAS and measures how fast your NAS is internally. Then you know if you have a bottleneck on the disks in your NAS, or it is your network/laptop, that is holding you back.

Trans for your answer @Zarocq , I tried with your tips, here are my results but I didn't understand a lot! :smile:

I think it's depend from my laptop hard disk which is a sata I, from another laptop with sata 2 reach ~65MB/s but very floating and slow down even to 20-30MB/s!

It looks like your transfer rates are 270MBps for write (1024 / 3,78) and 602MBps for read (1024 / 1,71), and they are not possible with standard SATA2 and HDD..

 

My result are much lower (93/75Mbps):

 

Serwerek> time dd if=/dev/zero of=/volume1/DiskStation/bigfile bs=64k count=16384

16384+0 records in

16384+0 records out

real 0m 10.96s

Serwerek> time dd if=/volume1/DiskStation/bigfile of=/dev/null

2097152+0 records in

2097152+0 records out

real 0m 12.62s

user 0m 0.52s

sys 0m 1.46s

 

can they be caused by the RAID 1 configuration? The disks are capable of transfer speed ~115MBps without any problem and I'm really confused about that situation.

How much RAM do you have in your NAS? This test only writes 1GByte, so if you have say 2GByte RAM, then the NAS is caching all your writes.

You have to write/read more than the amount of RAM in your NAS, preferably more than the double of your RAM.

1GByte RAM = 2GByte file. Just double up the count-number to 32768 for a 2GByte file.

A Sata drive is able to deliver ~120-130MByte/s sequential. If your NAS is fragmented, then your transfer speed will slow down.

 

These are the number from my NAS built on a N54L with 5 4TB WD Red disks and 2GByte RAM (see my sig).

Ok I tested my nas again as per your suggestions, count=65536 should be fine for 4GB RAM!

 

 

 

BusyBox v1.16.1 (2014-10-10 08:38:16 CST) built-in shell (ash)

Enter 'help' for a list of built-in commands.

It looks very bad :sad:

No, actually it looks correct with 1 disk in the system.

4096MB in 33.4 seconds = 122 MB/s = what 1 SATA disk is able to deliver.

In my eyes it looks fine. :smile:

Hello, my name is yosus and I'm new on this forum, I want to thank everyone for the support and I hope someone can help me.

 

I'm trying to build a NAS using this motherboard and xpenology. I've create the usb drive and boot from it using nanoboot, then select "Synology DSM 5.0 (upgrade/Degrade)" and then "Synology DSM 5.0-4493" (or other version). My problem is nic seems not to be recognized since I have the message "eth0 not RUNNING".

 

What do i have to do to make ethernet being recognized?

 

Thanks
