What information do you lose if you prune Geth? : ethereum

I’m studying the {hardware} requirement for Geth right here and I seen this portion:

On the time of writing (September 2022) a 2TB SSD is advisable for a full node working Geth and a consensus shopper. Geth itself requires >650GB of disk house for a snap-synced full node and, with the default cache measurement, grows about 14GB/week. Pruning brings the full storage again right down to the unique 650GB

Knowledge rising 14GB/week sounds very costly and therefore the flexibility to prune which brings information again to 650GB seems like a really helpful function…

However query is, what functionality do you lose if you prune? Are there some information you now will not be capable to entry?
