Unless you're serving some quite demanding clients, I'd expect 16GB in
an NAS to be a complete waste of money.
There is the rub! A flat file server needs a solid IO system, but not
much computing horsepower. In this respect, media files are no
different than any other files. The twist comes in if the server is
offering up video files in formats that are not native to the clients
and must recode the files on the fly. My main server has an Asus
Sabertooth 990FX motherboard with an 8 core AMD FX-8350 processor and
16G of memory. When doing simple file operations, especially primarily
reads, the CPU frequency usually hovers around 2.4GHz with at most two
or three cores running at moderate load and plenty of free memory.
When a request comes along to recode an HD MPEG-II file to h.264 or
vice-versa, the CPU clock jumps to over 4.0 GHz with all 8 cores
slamming away at over 80% utilization and the memory usage pegs.
IOW it all depends about what kind of NAS you're designing, and with
what kind of connectivity and software.
Absolutely.
