Geth eats to much space, can someone help ?

Hey together, i want to setup my own ETH node with GETH, so far so good, i bought a fast 2tb nvm 2 SSD and start syncing, now after near 6 weeks of syncing just 5 month are remaining but my disc space is near end, i have only 60gb left from the 2tb.

I assume the 60gb will not be enough for the remaining 5 month -.-

So what is here the issue ? Do i need to prune something or do i really need a 4tb ssd?

thanks for any help
