Netgear ReadyNas DUO performance: conclusion
Hello everyone,
After days spent on forums and attempts to reach solution for really horrible feeling from ReadyNas Duo performance speed, I feel an urge to make a summary of my experience.
I bought ReadyNas DUO 2 years ago, but didn't really have time to integrate it to my home network. I also bought 2,5TB harddrive (WD) in a good believe Netgear will once bring firmware that will make >2TB HDD's ready to use and meanwhile - NAS will map 2TB and drop disc space that can't use.
1) ReadyNas Duo mapped cca 276GB out of 2,5TB only.
- I decided to buy 2TB HDD and proceed.
2) Transmission speed was terribly low (2-3 MBps), jumbo frames allowed.
- Usual forum suggestions:
Did you try another computer? Yes, I have Alienware Aurora and Alienware M18x laptop in maximum possible configuration and W7 ultimate.
Do all network members support jumbo frames? Yes, entire network is a hi-end Cisco solution and all network members support (and have enabled) jumbo frames.
Does your network adapter have jumbo frames enabled? Needless to say - yes.
Is your ReadyNas firmware updated? ...Yes.
Journaling disabled? Yes.
3) Transmission speed is still terrribly low...
- After long time I was rejecting to believe Netgear woudl dehonest it's trademark by saying there is supported technology and is not, I tried out a hopeless idea, turned off jumbo frames and set MTU to 1492.
- Transmission speed went up to 30MBps - far from expectations, but acceptable with note: Buy another NAS.
Conclusion: Assuming Netgear ReadyNas DUO is an old product, even if you'd get it for free from someone, don't believe described functionality and well performing NAS at all. Could happen my specific piece is simply broken, but regarding to another forum posts - I believe I'm not the only one. Netgear is a very good trademark, releasing such a product, promissing functionality that it doesn't have... was simply a bad step. If you have issues with ReadyNas' DUO transmission speed and reach 30MBps, you are on top what this product allowes you to do, searching for solution is wasting of time.
Still - maybe I missed out something. I don't want to blame Netgear for anything, this is just description of point I reached after really hard try to reach advertised performace.

- The duo you purchased was obsolete when you purchased it - Netgear replaced it in late 2011. It was very competitive in its day, and I still use mine for back up.
Product reviews (e.g. http://www.smallnetbuilder.com/nas/nas- ... l=&start=6 ) and Netgear's published performance tests showed that it's peak read speed was ~30 MB/s. If you were seeing higher numbers than that somewhere, then you were likely confusing the duo v2 with the older v1 you actually purchased. The branding (duo and duo v2) makes them easy to confuse.
I don't what was going on with jumbo frames on your network, but you wouldn't the first poster to discover that they always don't help performance. Usually we do suggest that people with performance issues try turning them off. - Hello Stephen,
Obsolent or not, when you buy NAS with G-lan and jumbo frames support, you expect something. As well - from Netgear I'd expect different level of support when it comes to firmware and >2TB HDD's support. Nevertheless - main issue I see in jumbo frames: when enabled, not just the speed is incredibly slow, also FrontView keeps freezing. Solid manufacturers shouldn't offer technology that can't deal with. Reminds me of "wild china" products that often advertise tons of functionality, but when you turn it on, you get mess insted of what you'd expect.
I also can't advertise certain features in my products and then suggest clients to turn it off when experiencing problems - it's just not fair.

Anyway you must have everything in your network with jumboframes support. If not - speed is incredibly slow of course.
That's not Netgear fault.
Note:
You don't talk about Netgear product because NETGEAR Duo is rebranded Infrant Technologies ReadyNAS Duo product.
I don't think that this technology is bad, but it's too old. I'm not sure, it have Infrant IT3107 / 280Mhz CPU?- hitcap - I am not sure if you are looking for help on the JF issue or not. If you are, maybe start over with more complete info on your network, and maybe we can help sort it out.
Back in 2008, it was an excellent performer - here's one of the reviews: http://www.smallnetbuilder.com/nas/nas- ... o-reviewed It handled the biggest disks available (1.5 TB back then). But in the second half of 2011, much faster ARM products came out (from all the manufacturers, not just Netgear), that raised the bar on performance. Sellers of course cleared inventory of the older products as quickly as they could manage it.Hitcap wrote: Obsolent or not, when you buy NAS with G-lan and jumbo frames support, you expect something...
As far as I'm concerned you should have researched what you were buying before you purchased. And you should have resolved your issues when you bought it - when you might have been able to exchange it for the newer NAS.
If that is aimed at me, it is off target. I don't work for Netgear, and although I help out folks here, I have no clients.

Also, even if everything does support JF, there is no guarantee that speeds will improve. The physical network is still 1 gigabit after all.
JF reduces the packet rate on the network. That's all. This translates into fewer interrupts per second in the client CPUs. Sometimes that reduced CPU load improves performance, but often it does not. Even if it does help, 9K is not always the best max packet size. Wired networks tend to perform best with smaller packets, PCs often perform best with larger ones. You need to experiment some to find the right balance for your equipment.
Yes, it has the Infrant Sparc CPU. Though I think the duo was brought to market after the Netgear acquisition, so it was wasn't rebranded like the nv+.janforman wrote: You don't talk about Netgear product because NETGEAR Duo is rebranded Infrant Technologies ReadyNAS Duo product.
