5600 vs 7200 HDD in DX517?

[akahan]

In a DX517 connected to a DS920+ on a 1GB LAN, and used primarily for storage of media for playback using Plex, is there any playback advantage (e.g., number of simultaneous plays) in 7200rpm drives vs 5600rpm drives? Or is the bottleneck elsewhere? Thanks!

Both 5400 and 7200rpm disk will fill up the 1GB lan easily, so don't worry there. A 7200rpm has better access time, but that is irrelevant for multi media.
5400 rpm is less noisy, consumes less power and theoretically last longer.

Perfect, exactly what I was looking for, thanks.

Way back when…. When DV for consumer was “good enough” and non linear editing was (relatively) new for consumer, but available for those with deep pockets…..
I learned that abandoning 5400 and below drive RPM’s was a necessity, as, at some point things will align “Just So”, that even though on paper it should work….you will spend hours trying to determine why something that ‘had the bandwidth on paper’ JUST WON’T WORK!
7200 RPM drives with large cache, or 10K/15K drives…. If you could afford it, Was the Answer! At work, I’d order hand selected 7200 RPM Drives with custom firmware in them. To optimize for speed.
To this day, 7200 RPM Drives with large cache’s are the MINIMUM drives I use.
SSD’s Preferred, (Even do Raid0 arrays for ‘Temporairy fast storage’) but if HD: 7200 RPM at a minimum.
That’s where/when I came up with the 2.2 Multiplier: Calculate what bandwidth you need On Paper…. Multiply it by 2.2, and if your drive/array meets that spec, you can be confidant you will Never have to chase ‘Dropped Frames!’ Anything slower than 7200 RPM’s is a waste of money. $.02

Just looking at the network…

If you are using both of the DS220+’s 1 GbE LAN ports then it’s not a 1 Gbps network anymore. On a 1G switch the port to port would be 1 Gbps, but with multiple devices the network paths can achieve higher when all device-device activity is added together. With binding the NAS can serve multiple clients up to 2 Gbps, theoretically. Same goes for SMB multichannel.

That’s also assuming there isn’t a single 1G link between clients and the NAS’s switch.

Thanks - fortunately I am neither editing nor binding ports… I’m just not that fancy!!
