Hi,

A while ago I saw a link posted to a website that has read/write speed comparisons for different model NAS devices. Does anyone know what it was? I haven't been able to find it using google.

I have a D-link DNS-313 that can't quite keep up streaming some higher bitrate Blu-ray ISOs - the movie gets choppy. I am using VCD to load the ISO and PowerDVD 7 Ultra for playback.

If anyone else here has tried streaming Blu-ray ISOs through a gigabit network (I have a gigabit NAS, router and onboard NIC) - is the NAS upload speed likely to be the bottleneck?

Cheers

http://www.smallnetbuilder.com/component/option,com_nas/Itemid,190 has some comparison charts. Oh, and for what it matters i can stream a 11GB 1080i mkv of The Dark Knight over my wireless N with no issues what so ever so i'd say a gigabit LAN would work just fine.

Cheers that is the site I was looking for.

I can stream 720p mkv videos no problem. I should try streaming the ISOs from another PC with gigabit ethernet before changing my NAS.

I have a dlink313 as well, I dont have any bluray isos only rips though, so not really much help. Having no problems streaming 1080p rips to my xbmc pc, video peaks about 17mbs. The throughput on the dlink313 is pretty poor though so it could be a factor.
How big is said iso? and whats the average mbs of audio/video?

My ISOs are around 30-40GB.
Not sure of the download speed from the NAS, but uploading the ISOs via FTP I was only getting about 5-6mb/s.
The FTP transfer would actually fail before it completed so I had to use fun_plug for shell access and wget the ISOs from my PC (6hrs+ transfer time).

Probably would have been easier to just leave my movies on the discs!

Don't mean to be rude but should this sort of thing be allowed to be discussed here since having an ISO of a Blu-ray means that you have ripped it and in turn broken any copy protection on the disc, which is illegal in NZ isn't it?

Opinions are my own and not the views of my employer.

i work with a lot of nas drives and even though they say they have gigabit, it is usually the processor in the unit that slows them down.

Haha, if he/she owns it then the police will not even bother.
As far as i know the copy protection rules are being changed?

Cheap Gigabit NAS devices do not reach peak gigbit speeds, you would be better off using an old PC as a file server if you want to transfer that much traffic.

NOTE: Streaming 40GB over 100 minutes is 7MB per second.

No, the laws still make format shifting of video illegal if it is copyrighted.

However, apart from a mention of the dark night or two, it could've been assumed everyone was talking about non copyrighted blu-ray discs. After all your ever own blu-ray writer will set you back only $350, and theres nothing illegal about ripping your own/non copyrighted discs.

But because it was mentioned, i have a feeling the topic will be locked.

Do you have any recommendations for a faster NAS? QNAP has a single bay NAS with a 500mhz CPU but it's about 3x as much as the DNS-313 cost.

I've had a good run with qnaps, admittedly i've only used ones that are raid. I can buy qnaps at cost if you want me to price one up.

I went through this about a year ago, and in the end gave up -

1) NAS was either too expensive to get the thruput required,
2) was limited in the HDD dept - a dual HDD NAS was getting up there in $
3) The NAS OS was also hosted on the HDD, meaning if you lost the HDD, you would be hard-pressed to replace the faulty HDD. Same applies for dual (Raid) HDD NAS.
4) The cheaper NAS units were limited to around 15-20mbs transfer speed - generally slightly better on the reads.

Threw caution to the wind, re-jigged an older HP P4 with 1 gig PCI lan card, a couple of SATA adapters, threw in a few spare SATA and PATA HDD's, installed Windows Home Server, and away I went. Can add in HDD's as required, duplicate across HDD's, etc.

Can data to / from transfer at 200mbps (peak), but will generally truck along at around 75-80mbps

I'm no MS fan, but WHS is a pretty reasonable product, and does what it is supposed to do well. IMHO !

You could do the same thing in Linux, if you are so inclined.

Are you able to obtain the new TS-219P Turbo model?
If so what approx cost?

That is exactly what I did, put a gigabit nic into an old celeron 1.7ghz ubuntu box. works a treat.

I thought about putting together a PC instead of using a NAS, but I don't have the space for it or the time to do it. A NAS is quieter and uses less power too- some have some nice additional features as well e.g. BT Client,

Looking at a Synology DS109 or DS209 now, much cheaper than the NZ list price if you import them from from the US.
