Mercury Pro
24X DVD, 48X CD Read/Write solution

Mac / PC / Linux / USB 3.0
The All-New Desktop Optical
Configured for your workflow
Now with an updated design, Mercury Pro is the premier drive to bring optical media back to your workflow. With a sleek, durable aluminum chassis, and high-speed USB 3.0 interface, Mercury Pro delivers reliable performance that matches its good looks. It's cooler, quieter, and better than ever.
Universal USB 3.0 connectivity
The new Mercury Pro is plug-and-play compatible with both Mac and PC workflows, making it your versatile premium optical drive. With high-speed USB 3.0 connectivity, playback of optical media, data transfer, and archive all happen as fast as possible, with bandwidth to spare.
The perfect long-term archive solution
M-DISC sets the standard for long-term safe data storage, and the new Mercury Pro supports this revolutionary format, making it the ideal solution for reliable long-term backup and archiving. M-DISC is an archival-quality storage solution that protects your data from degradation and loss for 1,000 years or more.

M-DISCs use a proprietary layer made from inorganic, rock-like material for permanent data storage, protected from data rot and extremes of light, humidity and temperature change. Because the M-DISC ready Mercury Pro engraves the data into this layer, write once and read forever.
Reliability and support you can count on
Like all OWC drives, the Mercury Pro is built to the highest standards of reliability and performance. Because our goal is always 100% reliability, it's rigorously quality tested, and backed by our 1 year warranty and 24/7 Customer Support.

Please note: Apple's DVD Player application only works with an internal optical drive or the Apple's external SuperDrive. To play DVDs with this drive, we recommend the free VLC Player, which can be downloaded from http://www.videolan.org/vlc/.

Rating: 5/5 Fast, solid, reliable October 21, 2016 I've been using a small and lightweight, plastic housed, drive as my primary disc drive for several years now and had forgotten how pleasant it is to have a more substantial and solidly housed drive. With imperfectly balanced disks which would have caused my whole old drive to vibrate and bounce around and which the old drive sometimes couldn't read at all, this drive simply spins them smoothly. So far I haven't encountered a disk which it doesn't read fine the first try, and to date it has successfully burned everything I've thrown at it. And, it is FAST! This drive is very easy for me to strongly recommend to anyone who needs to add or replace a CD/DVD drive.

Rating: 5/5 Fine product June 14, 2016 It easily played my self burned DVDs which 2 other burners wouldn't recognize. I was worried as LG isn't normally considered to be a maker compatible with Macs but it seems to work perfectly in this case.

Rating: 4/5 Works well but a bit noisy May 20, 2016 It works very well but it is a bit noisy when verifying a burned DVD video compared to my previous OWC DVD burner. The other thing is that the supplied USB3 cord and dongle is too short. Order a 3 foot USB3 extender cable so that the burner is not in the way.

Rating: 5/5 Speedy Optical Drive (CD, DVD, etc.) March 19, 2016 Just received the unit and hooked it right up to my iMac. Worked without a glitch. Ripped 3 CDs in rapid order. Two went at ~30x speed, the other was probably scratched and only went at 5x. I'm pretty sure this one would have failed completely on my old Samsung portable drive. At the slow speed the drive was very quiet; at high speed it made a sound like "wind," but not for long as it was done so soon.

What can't be seen in the photos of the unit on the website and was not known by the OWC/MacSales telephone rep I spoke to, is that the drive DOES have an open/close tray button on the front, right side, just below the "super multi" label. This should be pointed out in the specs and photos, as I almost didn't buy it thinking it had no open/close button.

The power brick isn't too large and connects to the AC power with a standard power cable, so the brick can sit on the floor or wherever and DOESN'T block any other AC outlets.

Summary: after just a few minutes of use, I'm quite pleased with what appears to be a solid unit.

I would recommend this item to a friend!
