Title: Stream HD/Blu-ray Movies + Copying speeds
Post by: Zaim on April 03, 2012, 05:29:54 AM
Hi, Does anyone know if this will stream blu-ray movies to say a PC/ Media player (WD TV Live) ?

Also what transfer speeds can I expect connected to a gig router?

Thanks.

Yes, the DNS320 is capable of streaming Bluray media files, comes down to if the media receiver can decode them.

The max transfer speeds are upto 20mb/sec

Ah cool, do you have to use RAID or can I just have 2 separate drives in it with different data?

found a answer in the manual :P

Would appreciate if someone could post write/read rates when copying large files?

I can get an average 20mb/sec when copying video files to and from the unit. Its doesn't go higher than this.

Ah cool, thanks for your reply. I've ordered one now.

Are your seeing 20 mbps download speeds on a wired GB network? I would expect higher throughput.
Is your client PC NIC card set to GB speeds? Are you using Cat6 cables and a GB router?

Yes to all those. I've never seen anyone or any review hit over 20mb/sec so I've never questioned the speed. Its only a budget unit.

I get 24mb/s write and 35-40mb/s read. Awesome NAS considering the low price.

These values seem more aligned with what I would expect.

Ok, never spent any time looking at read speeds, but your right I max out at 40.1 MB/sec  :)

That's more like it!  ;)

we talking megabits or megabytes?

at most ive seen is about 5 megabytes write, which translates into 40 megabits.

read was a little better at about 15-20 megabytes, which translates into 120-160 megabits.

gigabit router, nic and cat 5e cables. no further than 2 feet between router and nic.

Why would we be using megabits?   ::)

Router and wireless card manufacturers use megabits to label network card/router hardware technical specifications (e.g. 300 mbps wireless network card, 450 mbps router, 900 mbps router, etc).

I have a gigabit router and gigabit switches throughout my house connected with CAT6, I have two 500GB Maxtor DiamondMax 10 7200RPM drives installed in RAID0 configuration. I see on average 20-25 MB/s for both read and write. FTP seems to be on the higher end of this average, and I sometimes see short bursts through FTP where the speed can reach 50 MB/s but that only lasts for a few seconds at most. I have noticed the more services I have enabled, (P2P, NFS, AFS, etc) the more it can affect the fluctuation of these speeds (always negatively). I try to limit the enabled services to FTP, and only enable the others when I need them, and then disable them as soon as I am done with whatever task I needed them for.

I have had no troubles with streaming HD content from this unit. For what I paid, I'm pretty happy with it. Definitely not the fastest NAS out there but its probably one of the best performers dollar for dollar.

All true. Many of the services on this device increase overhead and reduce performance. Users should be mindful of this fact and only enable the services they are using on a regular basis. Just enabling UPnP alone (on other ShareCenter devices I've used) has a measurable performance impact.
