We have set up a private Ethereum node for our blockchain application connected to the mainnet. The node runs on a server with 2TB SSD, 4 CPU and 6GB memory. It's been syncing for about a week and is currently at block ~5,000,000 (around 900GB of disk space).

Since it's taking quite a long time to sync compared to the fast sync mode - which also takes less disk space - I wonder if there's any obvious benefits to running it in the archive mode and if we could potentially run into problems if we were to switch to the fast mode.

Archive nodes are only necessary if you're going to be querying historical nodes that are no longer on the state trie.

That said, even fast-pruned nodes allow you to inspect some (configurable) depth of history on the state trie, so whether it's sufficient depends on your use-case.
