This is a OWC Mercury Elite Pro Dual with 3-Port Hub external storage enclosure for 2.5-inch and 3.5-inch SATA HDD and SSD drives with optional hardware RAID and a hub with 2 USB 3.2 10Gb/s USB-A ports and 2 USB 3.2 10Gb/s USB-C ports (one is used to connect to the computer). 0TB No drives included. Includes the power supply and cord, and a USB-C cable.Like new condition, very gently used for a few weeks. I changed to a 4-bay OWC enclosure, so I no longer need this 2-bay enclosure. Will ship in the original box inside the original OWC shipping box.
