After native macOS Sierra build from source of the latest tag, I installed and set up what I thought was a configuration which allowed me to store the large blockchain "blocks" files on an external (USB 3.0) drive.  I ran with this configuration for some time before realizing just how slowly it was synchronizing the blockchain.  I found the following issues:

• Bitcoin OPEN Issue 10736 (https://github.com/bitcoin/bitcoin/issues/10736)
• Bitcoin CLOSED Issue 10647 (https://github.com/bitcoin/bitcoin/issues/10647)

The latter had some useful suggestions to keep the "index" (and "chainstate") LevelDB folders on the internal disk as they are high i/o frequency.  I summarized my experience in the pull request 10922 (https://github.com/bitcoin/bitcoin/pull/10922)
which simply adds a new "file-partition.md" doc with example steps to separate the larger "block" files out of their default $datadir location while keeping the high i/o frequency "index" and "chainstate" folders on the internal drive.
If this information is redundant or better shared in a different fashion, please feel free to redirect me.
Thank you very much.
