Probably too late to help but I would strongly recommend BitCore
https://bitcore.ioThe api is better and much faster, it is built on top of bitcoind too.
You can see the guide on starting a full node
https://bitcore.io/guides/full-node/For your storage requirements, for long term stability I would suggest at least a 100GB hdd or ssd. The ram should be enough unless you are doing very intensive transaction analysis or other high computing services
ok. thanks.
not late, but this is new for me..
need this install too?
first need install bitcoind and after install BitCore or only BitCore?
