ReadyNas 3138
I have a ReadyNas 3138 which has a Quad Core Atom processor and I want to use for surveillence storage. We have three surveileence records with about 150 cameras. How do you think this system will ho...
Any guestimate on the MB/s the cameras will require?
Not sure. I'm recording at 8 fps on majority of the cameras and 6 fps on the rest using H264.

The bitrate is what matters. Also, whether the cameras are only recording on a motion alert of some kind, or if they are always recording.
It should be possible to get some sizing from your current storage system (perhaps with some help from your network IT guys). Most servers collect ethernet stats, so you would be able to get some average loading from that.
Are you trying to record in real time to the NAS, or is it backup storage for files captured on the DVR(s)? If it's backup, you probably won't have a problem. If it's real time, do I read your message correctly that the DVR(s) send(s) three multi-camera streams to the NAS, not one per camera? One per camera sounds like pushing your luck. Three might be OK.
Sorry, I should have spoof read my post. I have three Ocularis recording servers and right now my live storage is going to two different places, one being the ReadyNas 3138. I didn't purchase the ReadyNAS, my predecessor did, but I want to put it to use as the main storage for our surveillance system. I have around 150 cameras total. All of the internal cameras are recording at 8fps and the external ones are recording at 6fps, all using motion detection. I recently purchased some Western Digital Surveillance drives that I'm going to install later this week and I'm hoping they will improve performance quite a bit seeing how the ReadyNAS is just using regular cheap drives currently. I guess my question should have been this....
How much does the CPU matter in the ReadyNAS's performance vs the quality of the hard drives used?
