CPU for file server

[HPUser7]

I am a photographer dealing with 100MB+ raw files and tend through a couple hundred gigabytes a peak week. I am looking to set up an unraid file server for my onsite backup (as opposed to an 8tb hard drive I have attached to my router currently). When purchasing a CPU for the file server do I want to prioritize number of cores or clock speed based on the description of my usage? Or should I just go for the cheapest CPU I can find?

Cheapest, honest a 2c celeron will do just fine.

Find a used Dell Optiplex or a HP Z workstation with 4 cores / 8 threads and that should be plenty for you.

 

ATM, I'm running a FreeNAS VM on my main PC and I've dedicated one CPU thread and 4GB of RAM to it, and it works flawlessly (the bottleneck is my network).

Does transfer speed matter? And do you plan to have more one device uploading and/or downloading content from the server at any one time?

I will primarily only be uploading from my laptop. I have a gigabit Ethernet connection and plan to give the backup system a 512GB NVMe drive as a cache. I would prefer for the network to be my bottleneck so getting speeds of 100MB/s would be nice, though I would be comfortable with being able to backup ~250GB in less than an hour.

Then I would recommend at least  a core I5 2400 grade quad core processor.
