I'm backing up approximatley 25-30 tb, so i was thinking of getting a 5 bay synology nas (ds1522+) but everything seems confusing (I mean i am not even sure which synology one would work well for me there are so many product sku codes that my attempt to create a nas falls through).
I've picked 5 toshiba 20tb drives, so i'm hoping i can do dual redundancy and the odd disk (the 5th one) could be some sort of check digit disk if 1 drive fails?)
I've also seen Ugreen - not sure how strong this brand is and whether i can trust my data to be out in the open internet, or how secure it is (does it use truenas linux?)
ideally I want to have 40tb of space to play with (with redundnacy so actualy hard drives might be like 100tb capacity) but i need 40tb to play with
the other option is I have to make my own nas server, maybe using minisforum base hardware (although I haven't figured out which hardware yet)
