Slow speeds with Seagate Blackarmor NAS
« on: May 17, 2011, 05:54:10 PM »

I'm surprised to see speeds around 11MB on a gigabit LAN and the NAS is also gigabit.  I've been reading that when people take the DLink router out of the loop that there speeds get upwards around 48Mb or so. Or if they add in a non DLink switch put the equipment on that leg with the switch.

Are there some tweaks in the 825 that could help with the LAN speed for this NAS?  Seems odd to have to buy a new router or add in a switch to do what this should be doing already.  This is going to be an issue for streaming movies and especially HD via WiFi across the LAN.

I would also like to do my data backups to the NAS but when they hit around 60Gb it would take a long time to do a backup.

The best thing for NAS and is preferred is to add in a switch between the router and the NAS and other PCs.
Putting the NAS directly on a router will probably have inherent speed loss due to router processing and traffic management of any router. Why go through the router when doing file xfers when you can go from a PC thru a switch to the NAS.

ISP modem> router> switch< all connected devices to the switch.

I prefer to only connect necessary devices directly to the router, everything else is on a switch. Switches do the job well.

The DIR-825 is a router with a switch built in is why.  It seems odd that the speed is an issue and you have to buy a separate switch.  Other brands, apparently, are not having this issue based on what I'm reading.

Plus, if I had a Boxee Box I wanted to use WiFi which means it has to stream through the 825 anyway. Otherwise, to use this DLink product (825 and Boxee Box for that matter) I'm going to have to run a cable from the Boxee Box to the switch.

How do you like your Boxee Box?  What kind of throughput you getting and how do you have it connected? I assume Ethernet to the switch?

Ya I agree that the switch on the router shouldn't be effected by the routers processing of the other traffic and features however it's integrated and I can only presume that how they implemented it could be a factor. I saw a post that others had recommended using an extra switch when using NAS.
My experience has been to use a switch specially having more than 4 devices. LOL.

Besides using a switch, they are not impeded by any other processing of traffic or features, just wide open traffic between devices.


Love the Boxxe man. Streaming has been seamless and video is awesome. I put movie files on the server and watch them from there. I haven't tried WiFi yet as it's all been wired. Since I got the 825 the other day I plan on trying Wireless and see.

Nice!  I'd love to hear how the WiFi works out for you.  Clearly you have wired your Boxee to the switch then. What brand and model of switch are you using and what have your data speeds been to/from your NAS?

Also, I've been using Harmony remotes for years and currently using the Harmony One with my main system. I see I'm going to need a IR adapter to get the Boxee to work with the Harmony One (to go from RF to IR).

I have a HP ProCurve 24 port Gb switch. I usually see 50-60 xfers. One other reason for using a extra switch is that if there is streaming or file xfers going on on the LAN, anyone using the WAN side wouldn't be affected, specially for gaming. Both of my xboxes are direct to the router. PCs and other stuff are connected to the switch.

I'll do some testing maybe tonite or next week. Just picked up a pair of B&W speakers for the new theater room yesterday. Trying to get it all sounding nicely.

Ya just preferred wired connection if I can implement it cleanly. Wireless is good and does well however not as good as wired. Will be interesting to see what Boxee does over WiFi with the 825. I'll post results.

Cool.  Appreciate it.  What kind of NAS you have?

Almost bought some B&Ws back in 2003.  Went with Paradigms instead.

It's a server, PC that i set up to store files.  ::)

Ya hear Paradigms before very nice. Didn't have the funds at the time. Just getting to where the wiring and such is being put in. Gotta plan it all out for the audio soon. Got the projector in house now. Can't wait to get it all complete. Walk away with a pair for $500 + tax yesterday, hehe.

Which model of B&Ws.  Sounds like you're doing the house right.

Nice!  Almost got the 302s back in '03.  Another reason I went with the Paradigms is that I wouldn't have to buy stands as the 302s needed them.

I'm in a townhouse.  1100sf on two floors.  Nice place for me.  My system has way too much juice for this space.  When I first hooked it up I didn't have the sub adjusted yet.  Watched a movie that had a huge explosion.  Sent a shock wave through the six-plex my townhouse is in.  LOL.  I adjusted it immediately.

Router -> Switch... blah.  Just to keep the topic.  LOL

Okay...this sucks.  Picked up a Trendnet TEG-S80g gigabit switch.  Put my PC and NAS on the switch and my speeds are they same as if they were on the DIR-825.  10-11MB.  Sucks...am I overlooking something simple? Or do I have to dump a bunch a money into a managed switch?

Seagate is of no help. As usual point fingers elsewhere and make recommendations of using some sort of network sniffer but cannot make a referral to any program due "liability issues".  Said there is a program you can run on your network that will find the problem so you know what to fix. Never heard of an network app that does it for you like they described.

Apparently this NAS is just slow.  I've tried:
  • setting PC NIC to 9KB MTU Jumbo Frames
  • speed & duplex set to 1Gb Full Duplex
  • I'm using Cat 5e which should be just fine
  • Transmit buffers are 128 (matter?)
  • Receive butters are 512 (matter?)

There are several adanced settings for my RealTec PCIe GBE Family Controller.  Not sure if there is somthing else that needs changing.  The TrendNet can handle 9K Jumbo Frames. The 825 is supposed to as well and also the NAS.

THE PC NIC on board or card in a PCI slot?

This has occurred to me to.  It is built onto the motherboard.  RealTek.

I could try my laptop again to as I have not tested it with the NAS and switch.  Or do you find that the Gb NICs on laptops aren't so great?

Ok, PCI slot would definately show a slow down unless it was PCI-e. Built in should be pretty good.

I would test it all out.
One think you can do is remove the router from the line. You can set up manual static IP addresses on each device then connect to the switch and test the speed.

Make sure all 3rd party security sw is disabled, norton and the like.
