over gigabit ethernet?

I've just bought a gigabit switch for my desk to get rid of my 10/100 switch. I've plugged my laptop in with a gigabit nic and also my nas which has a gigabit port yet transferring a 5gb file as a test only managed 8mb per second.

To also test I plugged the laptop directly to the nas using a crossover cable and still only managed 8mb per second.

I think it's the nas which is the issue as it's a Lacie one and a bag of sh!te and not truely running a gigabit ethernet port.

Theoretical is 128MB/s, but it will be more like 100MB/s with overheads. Don't forget you will be limited by the speed of the drives in the Lacie, and unless they are raided or ssd, you wont max the gigabit lan. I dont however think they put meaty enough hardware in those things to drive gigabit lan throughput as I have a WD mybook on the shelf which doesnt even get close even though its got a gigabit network port.

I've only recently been able to max my gigabit out after switching to ssd and going ssd to raid 6 over the lan.

Thanks, so as suspected 8mb per second is a joke. Might just bin the piece of cr4p and just use my usb3 drive which flys. Wont be buying Lacie again that's for sure.

I get 15mb transfer on my 100mb network.

lol

i'm going to try laptop to laptop to test the switch and prove it's that piece of **** Lacie.

I'd blame the laptop myself, slow low powered drives used ? I have found that apart from the quad RAID set-up in my file server nothing gets close to the theoretical figures quoted...

P.S. I use a Netgear five port Gigabit switch and it's "invisible" in a good way...

An0n0m0us

Not the laptop, £1000 laptop with twin 7200rpm drives and as I say copying backwards and forwards over usb3 is lightning quick.

This

and when they are set to auto-negotiate they can 'play safe' and default to 100Mb/FD (or even HD when they're being awkward)

An0n0m0us

Nah not that, it's win7 and whether set to auto negotiate or 1gb full duplex speed doesn't change.

Tested laptop to laptop and get an intital burst of 192mb per second lol then drops to 100mb per second and then settles on about 40mb per second while testing copying an 8gb file.

The Lacie is using jumbo frame size and cannot be disabled. I've tried setting the laptop nic to enabling jumbo frame size and match that of the Lacie but then speed dropped to 5mb per second Upped both to 9000kb mtu on the jumbo frame size and this didn't help. So it's definitley the Lacie and the fact it's using jumbo frames that is a load of boll0cks.

How are you transferring files btw?

An0n0m0us

windows explorer via unc mapping to either other laptop or to lacie drive

Ant

tried ftp? i find that quicker when transferring

An0n0m0us

Nope can't be ar$ed with it, unc mapping should be absolutley fine. I've proven it's the Lacie pile of cr4p and so i'll have to replace it with a proper gigabit hard drive when one pops up in a deal.

Also check the limitations of your NAS

My ReadyNAS maxes out at 240Mbps (30MB/sec) peak, but usually runs around 180-200Mbps (22-25MB/sec).

Antivirus can also slow things on a slow/overloaded system.

Also if your using an out of date OS like XP, it may need tweeking. Vista and Win 7 should self-optimise.

An0n0m0us

Quad core i7 and 16gb ram with 7200rpm drives so av isn't playing any part I can assure you. I think I may have to sacrificially burn the Lacie at the stake for the devil that it is.

Ant

tried ftp? what speed does that pull?

An0n0m0us

No not tried ftp, it's the Lacie that's the issue anyway so will just wait for a decent price network hdd to come up.

Ant

I Only have a cheap Chinese nas thing and it does a lot quicker through FTP, that's why I asked

i have an icybox nas and have the same probs. gigabit nas, gigabit netgear router and 2 pcs connected with cat 5e cable and my throughput is similar. In fact wireless transfers are only a bit slower. its a pain backing up recorded tv to 1 of the nas drives
