Why would a router modem/router need so much onboard ram 1GB and 4 GB Flash memory my old PC has only 4GB DDR2
Linksys recently released their own OpenWrt router, the
WRT1900ACS, dual 1.6GHz CPU, 512MB RAM, similar other specs, but only 128MB flash. So really the Turris is rather similar to commerical OpenWrt routers but with extra flash - I'm sure the designers had good reasons for their decisions.
EDIT:
I should have also included this from the website explaining the design considerations -
More than just a router. The open-source center of your home.
Home router is necessary to connect you to the Internet but it is idle most of the time, just eating electricity. Why not use it for more tasks?
With powerful hardware, Turris Omnia can handle gigabit traffic and still be able to do much more. You can use it as a home server, NAS, printserver and it even has a virtual server built-in.
