This is a set consisting of a Synology 2-bay NAS "DS716+II" and two SEAGATE "IronWolf Pro 6TB" NAS-grade high-endurance HDDs (6TBx2). The DS716+II was purchased around 2017, and the HDDs were purchased around 2022. Both were in use until the spring of 2025. There were no reported issues during the period of use. This is being sold due to a NAS upgrade. The NAS accessories are as shown in the photos; only the LAN cable is missing, and everything else is included. (Main unit, power cable, drive bay lock keys x2, instruction manual, outer box) The HDDs will be packaged and shipped while installed in the NAS. There are no noticeable scratches on the main unit, but there may be minor scuffs.
