20 8MP cams for 30 days

At that scale the storage should be tiered in a SAN, with all the benefits that provides, with the server just providing the compute engine.
You got it. I figured it wasn't worth going into all the specifics. But it's good to know there's people out there that... Think retail price is the installed system price.
 
Sorry... I didn't say anything about amcrest cameras. I was just commenting that I'd just built a data server for Treaty work and a price. A bit tongue in cheek as I doubted anyone world be interested in that level of redundancy and performance except for governments and businesses that relied on historical data.
If you think this is bad you should see the 250k Dell server to invest and perform metrics on ISR data... And I was going cheap there.
you replied to someone who was asking for advice on storage for his amcrest cameras...
