Notes

For more information on the compatibility of each expansion unit, please refer to this article.
Please upgrade to DSM 6.2.1-23824-5 or later version before using it with 15 and 16 series models (excluding DS1515, DS716+, and DS716+II).
To have better performance, we recommend creating storage volumes physically located within the same NAS or Expansion Unit, rather than creating volumes across your NAS and Expansion Unit.
