## Long description

OWC Mercury Elite Pro 3.5" Silver is a single-bay external HDD/SSD enclosure designed for 3.5-inch SATA drives. It supports Serial ATA I/II/III interfaces with up to 6 Gbit/s transfer speed and connects to a host via USB Type-B (host cable to USB Type-A). The unit is supplied with an installed 3.5" hard drive providing a total capacity of 12 TB and is intended for use as external storage for backups, media libraries and expanded desktop capacity.
Advantages

The enclosure offers straightforward plug-and-play connectivity over USB using a Type-B port and a host cable to USB Type-A, and it supports SATA III speeds up to 6 Gbit/s for compatible drives. Its form factor allows horizontal placement with non-skid rubber feet or vertical placement on the included stand, enabling discreet desktop installation and stacking multiple units for increased capacity.

How to use
Connect the enclosure to your computer using the supplied USB Type-B to USB Type-A host cable. Place the enclosure horizontally on a stable surface using the rubber feet or mount it vertically on the included stand to save desk space. The enclosure is intended to be used with the pre-installed 3.5" drive; power the unit and wait for the operating system to recognize the external drive. No additional drivers are typically required for modern operating systems; format or partition the drive as needed for your workflow and begin copying files, configuring backups, or mounting the drive in applications that access external storage.
Usage recommendations
Place the enclosure in a well-ventilated area to ensure passive cooling through the aluminum chassis. For regular backup workflows, use verified backup software and periodically check SMART data of the installed drive. When stacking multiple units, ensure stable support and avoid covering ventilation surfaces to maintain heat dissipation. For use with consoles or media players, connect directly to the host device via the supplied USB cable and ensure the device supports external storage formatted in the drive's file system.
