So I was wondering, what is exactly the use case of owning a server rack with huge CPUs and 256GB of DDR4 RAM with 1PB of storage?
Obviously, I'm kind of exaggerating here, but it does seem that most homelabs are big server racks with at least two CPUs and like 20 cores in total.
Why would I want to buy a server rack with all the bells and whistles when a low-power, small NAS can do the trick? What's the main advantage of having a huge server, compared to an average Synology NAS for example?
Honestly, I only see disadvantages tbh. It consumes way more power, costs way more money and the processing power it provides is probably only relevant for (small) businesses and not for an individual like me.
So, convince me. Why should I get a homelab instead of a regular NAS?
As data hoarder this is a goal to achieve :)
You can do much more things much more efficient. If you're out for a NAS, get a DiskStation, even the simple ones with 2 slots are absolutely fine. Get a Seagate Exos X20 with 20 terabyte of storage, or 2 of them for a RAID, and you're good to go. Or build something yourself with an external case and a Raspberry Pi.
Right now I'm using Docker and I'm hosting an ActivityPub server and a front-end (client) for it, a web server, a Minetest gaming server, a web Git platform and a custom application for some specific logging i'm doing. The same server also runs a reverse proxy and a Docker management platform. All on one older SOC machine with a recycled 1TB SSD. I couldn't do this with just a NAS, even if the DiskStations are (were?) very "hackable".
If you want to do anything more than just providing files via network, build a custom setup that fits your needs.
