Hey guys, im hoping someone will be able to help me with this, I bought one of those lan server hdd enclosures from ebay but I am getting slow transfer rates for some reason. If I transfer from PC to PC I get about 8+ mB/sec but when I transfer to or from the Lan Server I only get about 3ish mB/s

It is connected to the same network using linksys wag54g router, iv checked the cables and settings and as far as I know they aint no way to change the duplex settings.

I emailed the manufacturer but aint got no response from them, hopefully someone will have a some advise for me.

That is odd, it is a wired network and the NAS is CAT5E?

Yep I have it wired to my router using a cat5e cable, I tried to google the actual lan server but dont really get any information.

Consumer NAS devices are slow compared to modern desktop PC's, even when you spend $1000 or so (because of their low-speed embedded electronics), so it's not at all surprising that a < $100 eBay device is under-performing.

If you really care about LAN performance, you should be using wired gigabit, and should not be expecting so much of cheap NAS devices.

A HD attached to a PC via a (good) USB2/firewire interface would likely give you much better performance. Shared over the network using consumer gigabit, it would come close to matching directly-attached speed.

This is true.. If you have a old box kicking around just make it a file server and add a gig nic in it.

Thanks for your replies, the reason I bought a NAS drive is because I assumed I would get the same speed as my all the other computers on my networks, it was small enough in size so it could sit on my desk and it doesnt make much noise at all.

I do have a old PC (got no where to put tho) which I dont use but would putting a gig nic in there work with my router? I thought you need a gigabit router too?

Yes you will need a gigabit switch too. I have a Infrant ReadyNas, and the performance is better, but as was stated before, even the more expensive NAS are relatively slow. I vote for the PC if you are up for the extra maintence.

Yes you will need a gig switch BUT you will see a HUGE differece with a regular 10/100 speed.

I couldnt just connect a gig switch to my normal linksys router could I?

No becuase the router cannot bypass its 10/100 switch that is already attached. It would work if you could say replace the 10/100 with the 10/100/1000 switch but you would have to connect the 1000 with one of the 10/100 ports.

Yes, you can. The gigE switch will talk to the router at 100 Mb/s. Your internet connection speeds won't benefit, but you will get internet connections through to the gigE switch. One of the nice things about standard gigabit is that it's backwards-compatible with 10/100.

Even with a router equipped with gigabit ports, the WAN port would be much slower, so you wouldn't get any benefit from having a gigabit port on the router connected to a gigE switch. Of course, the point of going gigE is not to improve internet speeds, but to improve internal computer to computer transfers on the same gigE LAN.

Connecting a gigE switch to a router costs you 1 gigE port, which you need to remember when picking your switch. Fewer ports are cheaper of course, more ports could last you longer. One of the cheapest, but definitely well-performing, switches would be the D-Link DGS-1005D at around $35 USD.

So if I buy a linksys gig switch and connect it to my normal linksys router all the pcs I conenct to the gig switch will run at 10/100/1000 keeping in mind they will need to have gig lan card and using cat6 cable right?

Yes, but cat 5e cable is sufficient.

You should also note that you'll be drive-speed limited in addition to NIC and switch -- 30 MB/s is a reasonable target for single drive to single drive transfers on average, and at this speed, specific gigabit NIC and switch selection, etc., aren't very important.
