I’d like to add I’d agree with the parent comment and add some specifics.

Buy storage servers from 45drives they basically build same hardware as Backblaze uses. Add copper 10G nics to the servers.

Get necessary switches 10G with 40G uplink ports. Whatever your favorite. Use 10GBaseT to the servers.

Install hardware in a quality data center. Like one of theirs -

And get 10G virtual cross connects to AWS.

Back of the envelope calculation you need 30TB raw, so about 60 servers. They aren’t really that power hungry so 10 per cabinet. 6 cabinets. at least 6+2 switches.

Software wise you have lots of options with this infra. High upfront cost but low MRC vs all other options. Assuming you have skilled sys admins who know what they are doing.
