NAS storage is no where as fast as direct connected usb drives local hard drives etc. It has to travel across the wire or wireless not supprised you are seeing this with video at all since video needs al lot of speed and is very time dependent. NAS storage was never desiqgned to be the speed of local attached drives SAN's give you that level of speed. NAS is for storage backups etc. Copy files off NAS to local pc and run

 

Hello Networks, thanks for the reply, I am surprised that USB is faster as I was thinking that network devices should be faster especially as the a network has a working speed of 100 mbps (or greater if gigabit) and USB only 12mbps.
So I have decided to make use of the USB hd connection of my router and will buy a Hitachi - XL-2TB Desktop hard drive, which is also cheaper, I realise its not quite the same network result.

 

in most cases the network is faster then USB but with NAS devices if you are not careful enough the NICs they use for them are very cheap and can only support certain bandwidth of traffic for incoming and out going ..yes they will say its a gigabit NIC but very very cheap one
if the device has the option to tweak those settings under network then try that if not then try your way

 

Thank you loda117, that's very interesting its a shame this is not mentioned in equipment reviews, as I have not found an exact explanation why some NAS are very much more expensive than others this could be the reason, buts does it make such a difference to the cost.

 

well david this def does because the better parts cost more
so before buying anything now a days specially don't look at the cost too much but to look at the specs look at them at the manufacturer's website and make sure to know what you are getting before buying
I have 2 8TB NAS sitting right now not doing anything because the previous IT guy was thinking of using them for backup and ya they share things fine but writing backup to them is just horrible 300Gb in 10 hours so always research
