So, storage is probably the biggest concern for Bitcoin self hosted nodes, at least full nodes is that the storage requirements might outpace what general consumers usually have or require. I don't think it'll be an issue for the capability we have in manufacturing larger hard drives, but it'll be what is available to the general consumer at a decent price, which the lesser demand probably means a lot of people could be out priced. Thoughts?
It's valid concern, but IMO time for initial block download (IBD) is bigger concern. I expect some people who interested to run full node discourage time for IBD could take some time.
Drive prices are falling insanely fast even with all the chip shortages and shipping issues all over the world. I just got an 18TB drive (on sale) for $300 1 & 2 TB are under $50.
While I know that may be a lot of money for some people in parts of the world those are new prices. I have seen 1TB used for under $5 in places.
Time to download is probably not as big a concern then people who have bandwidth amount limited plans.
Yes with 1meg download speed it can take close to 2 months to download the entire blockchain. BUT if you only have a 100GB max download a month total before extra billing or fees kick in then do you pay more or take 6 months to download?
