Officially: to access NAS, get raw market-data files (tens to hundreds of gigabytes a day), not needed on laptop every day, but only once in a while to fix or analyze something.

Really: because I can, and it is fun. I upgraded my home lan to 10G, because used 10G hardware is cheap (and now 25G enters the same price range).

"because I can, and it is fun." The best answer! I am most of the way done with upgrading most of my homelab to 100G from 10G, but there really isn't a practical reason for it. 100G has dropped in price so much as datacenters are all about 400/800G now.

Nice! Cool to hear from a fellow admirer of overkill-lan setups ;)

Which cards do you prefer for 100G, and what is the situation with dacs/optics?
