Question about os choice in my specific use case
I want to build a NAS for cloud storage, streaming and surveillance recording. I have a i5 11th gen and 16 gb ram. I was thinking about using unraid because i dont plan on buying all the drives i need in one go and it is cheaper for me to buy mismatched drives used ( ie: 2 4tb wd purple then 2 8tb wd red plus, then 2 8tb wd gold). Is it better to just try and get 2 8tb drives in one go and use a free os? I dont need tooo much storage but i also dont have tooo much money. I was thinking about 500-1000gb of space for cameras, about 4-6 tb for cloud storage and about 4-8 tb of 4k movies and maybe music. Can anyone give me a piece of advice? I would pay the 250 euro price for the unraid (with lifetimes upgrades) if it means saving costs on the drives. I also plan on adding 2 ssds maybe as cache or for apps and movie thumbnails n stuff. Thanks!
My budged is around 400 for drives (hdd, ssd)
