Ideally one that can use more than one disk so that i can expand it later when i can. Have some minimal experience with Synology since there’s one at work and i have interacted with it a couple times and like the interface, but am not married to any brand as long as it works.
Located in EU if it makes any difference.
Seems like OP wants a hardware-based solution. But for anyone else considering setting up a PC-based NAS, I’ve had a great experience using Open Media Vault. It made setup far easier for me, and it has been quite reliable even with USB-attached drives.
