Does anyone in here using N5200 for video editing storage devices on the network?
i have try using N5200BR with RAID 5 on video editing the performance on copying is fast but when writing some data from the editing fail due to report "destination disk too slow".
If anyone have same experience i might to know your comment too.
Thanks!

I have not tried the N5200 for video editing but a few comments. Video capture and encoding at high resolutions demands high disk throughput. The demand depends partly upon what format your are storing in. Uncompressed SD-TV can tax even an internal ATA drive running at 35 -45 MB/sec sustained rate. Compressed formats use considerably less storage space and bandwidth and will run fine with the same drive. Many software manuals will spell out write speed requirements. Typically you are better doing the editing on a fast internal hard drive and using external storage for archiving and playing.
Part of the issue if you are using a networked drive can be the network speed. To even try this I would recommend using a giga LAN. 100Mb/sec is marginal for doing this even with no other LAN traffic. Don't use a hub use a giga rated switch or connect direct to the n5200 from your PC.
You might want to think about using Raid 0 as well but this won't help much if you are on just a fast Ethernet LAN. The network limit would be the limiting bottleneck.

I use the N5200 (5x400GB in RAID5 mode) for storage when editing minidv footage in Cinelerra. My workstation has a gigabit network connection (1500 MTU. IE, no jumbo frames) and it works reasonably well. Using a 100MBit switch is too slow, even though minidv footage bits per second is less than 100MBit. IO caching is certainly helping out, as the max IO on the N5200 is roughly the same as a single SATA drive in a desktop.
