Are these your write speeds?For your NV+ (v1) units about 10 MB/s is what you'd expect for write speeds.The NV+ is using hardware from early 2006, so the hardware is quite old.A newer ReadyNAS may perform better. Though using a 200 Mbps Powerline adapter the performance you'd get might not be much better (200 Mbps may give you up to around 20 MB/s, but due to various factors your performance may be less). Cat5e or newer ethernet cables are better than ethernet over power.

you may be limited by either the NAS or the powerline adapter. Those things tend to never get their full speed and global performance vary depending on installations. Direct cable is always the best, but I think that if you got powerline in first place this is not possible. You could either use a better powerline adapter or use wifi N or AC if possible. look at real throughput for powerline adapters : http://www.smallnetbuilder.com/lanwan/p ... harts/viewNV+ is not the fastest NAS on the market either. You could connect it to your PC to see the max speed (just give the two devices fixed IP on the same range), that way you'd know what you can squeeze out of it.Jumbo frames could work, but your router/switch has to support it too, and given your computer I expect you to do something else than browsing the web, jumbo frames may increase the ping in games for example.

As mdgm suggests, newer NAS are much faster. Though it seems to me that you might want to probe the bottlenecks here, since the NV+ is capable of ~15 MB/s write speeds for large sequential files, and you aren't seeing that.-I would not recommend sending jumbo frames over powerline. -Also, the 10 MB/s you are seeing is suspiciously close to the limit for fast ethernet. So I'd confirm that you have gigabit speeds at both the PC and the Nas (and the path inbetween). I'm not sure I have the topology straight here. I am thinking a Router -> Powerline -> Gigabit ethernet switch -> Lenovo+NAS???If so, the PC and the NAS are connected to the same gigabit switch, and powerline (and the router) are not being used when you transfer between them.But if it is connected differently, then perhaps powerline is on the path - in which case it likely is the bottleneck. Your powerline module connects with fast ethernet ports, so it is not capable of more than 10 MB/s transfer, I believe your router is also fast ethernet. If you are interested in raising the performance, I first suggest using nastester as the benchmark (http://www.808.dk/?code-csharp-nas-performance). It's a free download, and provides consistent results that can compared with what other forum members get.I'd suggest benchmarking your setup "as is" first, then trying a direct connect test - similar to xeltros's suggestion.

I assumed that the PC was isolated in its room so I had : NAS => switch/router => powerline A => powerline B (in the other room) => Lenovo But looks like I read a little quickly, re-reading the first post, it seems you are right and that the PC-NAS circuit only uses the gigabit switch. 10Mbytes/s is indeed pretty close to the 12Mbytes/s limit of the 100mbit/s connection. I think you are asking for a cable check here ;) @clingon, do you use category 5E or better cables ? old cables using cat5 (not 5E) are not compatible with gigabit speeds. Can you test with another cable ?

A cable check is reasonable. It's also easy to confirm that both devices have negotiated gigabit - usually also the LED status on the switch has a different color for gigabit than fast ethernet.

Speeding up data transfer?

My ON NETWORKS PL200-199UKS 200 Mbps Powerline (connected a D-Link DSL-3680 router) is feeding a tp-link tl-sg1008d gigabit Ethernet switch, which is hooked up to my Lenovo i7 3770 3.4ghz 16gb PC & NV+

My drag & drop write speeds are topping out at 10mb/s & always have.

Is there anyway to speed this up? I'm not sure if enabling jumbo frames would be possible in my set up or actually help?

Thanks :)

The tests were done on RAIDiator 4.01c1-p1 which was released early 2008.

Since then a number of packages have been updated to improve compatibility with newer client OSes etc. If the newer versions of those packages consume more resources then the max performance you can obtain may be slower than what is in the article on kb.netgear.com that you linked to.

I there a reason you are staying on 4.1.10?

Is that because of the reported compatibility issues with some 3rd party 1GB RAM modules on recent firmware?

I think at some point you will need a new NAS.

You should be able to see under Network > Interfaces in Frontview if the NAS has a gigabit (1000 Mbit connection). It needs to be set to auto negotiate to be able to get a gigabit connection.
