Help with max speeds with Qnap TS-659 Pro II ??

[kek]

I've been racking my brain for the past 2 days over this, and I've tried everything, but I can't seem to get higher than a 65MB/s write rate to the NAS.
I'm satisfied with the read speed of >100MB/s

I'm running 3 x 2TB Hitachi drives (on the compatibility list), in a raid 5 config.

They advertise the unit of being able to achieve 100MB/s write rates, and I'm rather depressed that I can't achieve this, but I can with my old Win2003 SBS server with same drives in a raid 5 with a rocketraid controller.

I've got my PC hooked up to my server and the NAS via the same Gb switch. I've tried changing ethernet cables.

Is this unit capable of being written to at 100MB/s ??

Most likely yes given an optimal configuration and testing environment but probably only very rarely in a normal non-optimized home-environment.

You get some clues from the Qnap specifications of the testing:

• FTP/SAMBA Testing Environment: Intel Core2 Quad CPU Q8300 2.50GHz/ 4GB DDRII RAM, WD640AAKS 640GB, Windows 7 Enterprise 32 Bits,Intel PRO 1000 PT Dual Port Server Adapter 82571
• FTP/SAMBA Testing Method: Connect the TS-659 Pro II and PC to switch, upload/download 5GB File without Jumbo Frame, FTP Tool: File Zilla

I'm sure the Windows-client used was tuned for speed. Additionally they say RAID 5 was used and I can only guess that they used 6 disks to take maximum advantage of the striping factor.

When smallnetbuilder.com tested the very similar TS-559 Pro II, they were pretty close. The slight deviation is likely to be explained by subtle differences in the testing method.

My 559 Pro II with 5 slow Samsung F4 in RAID 5 is capable to get > 100 MB/s according ATTO benchmark however a fast network (PC, router, switch, ...) is a precondition.

Any idea's as to why I can't get the faster write speeds?
I'm thinking of returning the unit, as it's basically not able to achieve advertised claims, or I have a faulty unit.

My PC is faster than that machine, and I'm running the read and write tests from my SSD with the same file transfer, to ensure the testing is accurate.
My current SBS2003 server has the same 3 x 2TB drives, and I can read and write to it at over 100MB/s, so this proves this combo is able to achieve the speeds, but seem to have much slower write speeds in the QNAP in the same configuration.
My network is not the issue if I can actually achieve the speed with other devices on the LAN.
Watching the transfer happen at half the speed basically is rather annoying, knowing it should be able to do it.

PC,SWITCH,ROUTER are all capable, see original post, and above, but the fact you can do this on a similar unit proves mine should be able to do so.
I might go an get another 2 or 3 discs, and see if if fixes the issue, but I shouldn't need to do that as I've already go the same 3 discs performing > 100MB/s read and write in a PC based server.

If the precondition is the unit needs 6 disks in a raid 5 combo to achieve this, it should be clearly stated.

The only way that speed is achieveable for me, is to use ftpzilla and turn transfers to 5, and then I can get better speeds.
It's not constant/average, but it seems to be able to go to those speeds for a while. It seems to prefer larger files then it will transfer faster, but alot of smaller ones transfer slower.

Not an elegant solution but I can live with it and it gets the transfer to server done faster.

Yes of course.The overhead with managing multiple files will slow file transfers down considerably.

All speed tests are always only done with a single large file, as that is the only thing that produces comparable results. It is also stated in the Qnap specifications that they tested with a 5 GB file.
