I am aware of the problems when both reading/writing HD video to an unRAID system.

 

Can unRAID handle reading a 25gb HD video file with an average bitrate of 20Mb/s to one computer? After looking around the forums at permformance tests it seems like this should be possible. Do you think I would ever receive a glitch while playingback video at 20Mb/s?

 

Thanks

Actually should work with multiple streams.

 

Will you ever receive a glitch?  Here are possible sources of glitch:

 

- If you are using the network for other tasks it's possible that your read stream could get locked out long enough to cause a glitch.

- If the source disk experiences a read error it's possible you would see a glitch due to disk read retries.

 

I play HD transport streams from my unraid all the time without issue.  Very few of them hit 20Mbit but a few are close.

you can even play 35mbit+ hd files without any problems....

Okay, the worst case scenario that I ever see being possible for me is this, and I was wondering if the unRAID server can handle that.

 

Two HD transport streams recording, two SD MPEG-2 encoded streams recording, and watching HD on two different PCs, with a third PC playing music.  Actually the true WORST case scenario for this would be all of this happening while I was trying to download games using Steam to the unRAID server as well.

 

I figure the HD streams recording would be 15-20 Mbps (although I guess the possible maximum per stream is 40Mbps?), the SD streams, well I'm not quite sure what bitrate they'd be, but I'd estimate 5-10 Mbps.

 

Preferably, I'd need at least 100 Mbps sustained write, and around 100 Mbps sustained read.  Is that type of performance possible?  What would be the average sustained read/write for the unRAID server?

If you really need that, unRAID probably isn't your solution, IMHO.

Well, what kinds of average sustained read and write speeds are you getting?  That would be more helpful.

 

Keep in mind that this is Mbps that I'm talking about, not MB/s.
