 blockchain data. By default this is the _.bitcoin_ subdirectory of your
 home directory. Depending on your configuration, this can use from about 10
 gigabytes to almost 1 terabyte as of this writing, with the maximum size
 expected to increase by several hundred gigabytes per year.

 deleting old blocks. Use this on a resource-constrained node that can't
 fit the full blockchain.  Other parts of the system will use other disk
 space that can't currently be pruned, so you will still need at least
 the minimum amount of space mentioned in the +datadir+ option.

 this size on high-end hardware to read and write from your disk less

 expense of using your disk more frequently.
