Comes with 4TB (2 x 2GB) of Western Digital Black Enterprise storage drives, AC adapter, spare HDD mounting screws and a set of keys to lock the hot-swappable drives in the unit. Will arrive factory-reset and in original retail box, hard drives have been securely wiped and installed in the unit.

I recently upgraded to a 5-bay Synology NAS after running this DS713+ and falling in love with Synology.

I'm sure there are plenty of reviews of this awesome little NAS box you can read... other than the 2 Enterprise drives included, this unit is pretty much stock as found in the retail version.

Please don't hesitate to ask questions!!
