Re: Bitcoin will increase the sales of storage devices at the end of 2015...
Even with 40 GB at the end of 2015, my 1TB HDD can handle it, probably another 5 years as well - probably the HDD will die sonner before I need to upgrade 
Well as long as someone in this thread isn't using a 20GB Solid State Drive from a few years ago there is not really a concern of maxing out space
Otherwise I would start considering moving it somewhere else lol.
