Mercury Elite Pro
12TB 3.5-inch USB 3.2 5Gb/s External Storage Solution

3.5-inch USB 3.2 5Gb/s External Storage Solution
Continuing the Legacy
The Mercury Elite Pro began OWC’s rich, storied history of storage solution innovations nearly 20 years ago. It has lasted the test of time by continuing to offer an incomparable blend of performance, quality, and value in a single-drive storage solution. The latest generation upholds our commitment to excellence and offers customers convenient access to their data with even more space and higher transfer speeds.
An Essential External Solution for Everyone
Photos, music, and videos are a part of everyday digital life. Add in presentations, reports, record-keeping, and correspondence, and the result is a staggering amount of data that needs to be stored in a single, accessible location. The Mercury Elite Pro is an essential desktop drive for creative pros, small businesses, home office users, and families with ever-growing storage capacity needs.
Housed in a rugged, solid aluminum enclosure, the Mercury Elite Pro is built for modern data management with a high performance 3.5-inch 7200RPM hard drive. It can be used for a variety of personal and business needs including:
  • Pro-level video editing projects
  • Time Machine and File History backups of important business data and irreplaceable personal photos
  • Consolidating files from multiple smaller drives to a single location for faster, more convenient access
  • Migrating data from an existing machine to a new computer
  • Expanding game storage of console gaming systems
  • Freeing up space on a computer's internal drive to improve performance
Purposefully Designed
Offering an ideal blend of form and function, the Mercury Elite Pro’s fanless, brushed aluminum chassis provides maximum heat dissipation to run quietly cool while the shock isolation design keeps the drive – and your data — safe and protected. It fits discreetly on any desktop with the included vertical orientation stand. You can also place it horizontally, using the included non-skid rubber feet, and even stack multiple units to create a capacity “tower of power”.
Ready for Play
The Mercury Elite Pro isn’t just all work and no play. Besides saving and backing up computer data or functioning as a workhorse drive on set or in the edit suite, it can be used to watch videos, listen to music, and view pictures through your gaming console or attached directly to your Smart TV.
Gain Critically Needed Gaming Space
With their stunning realism, modern games have grown to an average of 40GB per game. For example, Xbox One gaming system’s standard 500GB internal drive will only hold 12 “regular” games. How do you play more games — including 4K games that are up to 100GB in size — without uninstalling other games? Easy … for every 1TB of Mercury Elite Pro capacity you add as external storage to your console, you’ll gain space to store up to 24 average-sized games. Besides eliminating the limitations of your internal capacity, you’ll gain the ability to offload the games you play most regularly and potentially load and save them faster.
Certified for Demanding Use
We understand having confidence in gear reliability is paramount to creative professionals. That’s why every Mercury Elite Pro pre-configured solution undergoes a multi-step performance certification prior to shipping. This ensures it arrives operating properly and immediately ready for demanding use.

  1. Sequential read/write (max) performance numbers are based on testing 14.0TB Toshiba HDD with AJA System Test (4KFull resolution, 64GB file size, 10bit RGB codec, file per frame test).
  2. If movie playback from an external hard drive and movie format is supported by your Smart TV.

Rating: 5/5 The Best Drive For The Money. May 18, 2021 I am very satisfied with my purchase. Upon receiving it, I immediately formatted it and created two partitions: One for superduper, and one for time machine. I then proceeded to do full system backups. It worked great.

Rating: 5/5 Excellent enclosure April 27, 2021 Works as advertised! This enclosure is fast and is of high quality. No complaints. I keep this plugged in 24/7 as a remote NAS via router. I use it as a backup drive for all of our computers. I will probably buy another!

Reviewer: aapple Location: California Age: Over 65 Experience Level: Power User Owned Product: less than a month
Rating: 4/5 Good Quality but July 9, 2020 I was really taken aback by the power connector being different from all my previous Mercury Elite Pro enclosures. That means I do not have interchangeable power supplies anymore. This one is a smaller coaxial connector than the others. I also notice that this one powers down the drive without OS interaction. Another difference. Neither is a show stopper just unexpected and not (AFAIK) included in the details of the product description. It is now in full use and working well.

Rating: 5/5 Excellent product, fully supported July 5, 2020 Didn't need help on this order, but have relied in past on OWC support to determine product required for the task. As typical with OWC, needed cables included in the package. Device itself well-built, easy to set up and useful instructions included. I've been ordering from OWC for decades and have never been disappointed, either with quality of product, technical service or customer service.

Rating: 5/5 Reliability in a box June 19, 2020 I was able to format my new drive without any difficulties. It connected immediately to my Mac Mini. This is the second external hard drive that I bought from OWC. My first one is still going strong after 5 years. This drive handles 1 part of my backup plan (Time Machine) The drive runs silently and has its own power supply.
