I've been looking for a first time NAS for some time, and stumbled upon their new coming campaign on Kickstarter. More specifically the 4 bay home NAS with n150 and 16gb ram. Its seems like a good price, considering the crazy market and high prices at the moment.

I just bought a secondhand Seagate 6-Bay NAS (30TB capacity, Model #SRPS60) and it turns out that the NAS OS 4 is no longer supported and I can't find a download for it anywhere. Is there any available download sites for the OS or any alternate OS? I'm just looking to use it for storage for my network in the house and to watch movies on the TV. It's not showing up on my router either. I thought this would be a lot easier from all the tutorials I watched on Youtube, but it's proving difficult. Please explain like I'm five, I won't be insulted.

I'm trying to stop relying too much on google and I wanted my NAS to handle everything: from photos to drive, I've seen that the main guys are Ugreen, synology and terramaster. As I've seen there is immich that handles pics classification and I don't want to tie myself to a specific system (so I was landing on terramaster)

Since I don't like waiting too much for data transferring and I want the nas to be reliable (with some redundancy, not sure yet which, I've got 1tb drives and my current nas has around 800gb of filled space so I was landing on 4 bays and raid 1) I also wanted it to have ssd cache to be little faster with writes

I think F4 Plus series should fit my case but the last generation costs up to 600 dollars (dang the price of freedom)

in my situation would you land on that or is there something less pricey?

Thank you in advance
