Implementation of the server for the return of mp4 files. Correct server specification?

Question

Network administration

There is a working server on nginx for serving small mp4 files 200-600mb with the characteristic: Xeon L3426, RAM 16 Gb, 2 x 2000 TB SATA RAID 1, port 1 gigabit traffic is not limited, I set up a good system. admin. Everything was great, the video loaded very quickly, but then the traffic came and when there were 40-80 people watching per minute, there were freezes. It turned out that the HDD can not cope with the load, several admins said that you need to install an ssd.
Please tell me a server for an adequate price with similar characteristics: 1 gigabit port, ssd capacity 2-3tb, amount of traffic from 100tb (ideally unlimited) per month, 16 GB RAM. Perhaps there is an option to optimize the load and leave the hdd?

Answer 1

Turn on block reading with large handles and aio in nginx and everything flies
