I have a freebsd server with a bitcoind server. But the blockchain is getting to large for me. So I just bought some new sas drives so I can keep it up. I now have 218GB of total space. 40GB is for the OS, programs and all files. The rest is for the blockchain(178GB). I do not want to buy more SAS drives than I have now.
I am afraid that the blockchain will get to big again in 1 or 2 years. Is there a way to reduce the blockchain size or is there a cryptocurrency where this problem is solved?
