Why would you need 2 TB SSD to store 512 MB of data? (we are talking about running a node here, right?) Even if you wanted to store the full blockchain 2 TB HDDs are cheap and would be enough for long time to the future.
How do you maintain all blockchain when block size limit will be 8 MB? Blockchain is almost 50 GB already. It'll be 63 GB before new year. Imagine we see 8 MB blocks every 10 minutes. Even 2 TB would be obsolete in 5 years.
If you don't want any problems you don't store your blockchain in HDD. You need a good SSD. Running Bitcoin Core is very expensive even right now.
Then where will all these transactions come from suddenly? You know that the 1MB blocks were not full until the spamming began? It is not imaginable that suddenly 8MB blocks are always happening. Even spammers could not afford these costs.
So you shouldn't fear these block sizes.
