Located alongside power and USB 3.0 ports on the back, a rear power switch turns the drive on and off.
SMILE SOFTWARE DISCLABEL FOR WINDOWS PRO
Measuring 6.6″ wide by 8.3″ deep by 2.2″ tall, the new Mercury Pro is a large and solid-looking external drive, using a Mac-matching sandblasted finish on the front, sides, top, and bottom, except for a large stripe of brushed metal on the centers of the top and bottom surfaces. A subtly convex button on the front right side manually opens and closes the disc tray, though your Mac can eject a disc in software. There are also 100GB M-DISCs, which sell for $20-$25 per disc, and are not compatible with either Mercury Pro, as they require a BDXL M-Disc burner. These 25GB discs work with the $135 Mercury Pro Blu-ray burner, and can be had for under $5 each in bulk OWC sells them in 3-packs for $14.97 or 15-packs for $67.50. Next are 25GB Blu-ray Discs, which is enough capacity that eight discs could fully back up the average person’s most precious photos.
The first are 4.7GB DVDs these are the only M-DISCs that work with the entry-level $78 Mercury Pro, and sell for $2-$3 each. There are currently three types of M-DISCs.
Department of Defense,” resisting “extreme conditions of light, temperature, humidity and more.” As blustery as the claims may sound, independent tests have subsequently demonstrated their superior resistance versus standard recordable optical discs. M-DISCs will certainly survive much longer, and much harsher conditions, than typical recordable discs. Millenniata, the developer of M-DISC, boldly promises that “your data will be safe for centuries,” and notes that the discs have withstood “rigorous testing by the U.S. While the chemically-induced color changes in standard recordable discs wear off over time, M-DISC’s pits - like vinyl records and professionally-mastered optical discs - remain intact so the disc can continue to be read for years. Unlike most recordable CDs, DVDs and Blu-rays, which store data by making microscopic color changes to their rings, an M-DISC writing surface becomes physically pitted with real grooves during the burning process.
OWC’s new Mercury Pro ($78/$135) external drives are designed to help Mac owners burn M-DISCs. Separately, Millenniata debuted M-DISC, an archival disc technology that lets anyone burn DVDs or Blu-ray Discs guaranteed to last “centuries.” While M-DISCs must be written using new burners, they can be read by traditional DVD and Blu-ray players, ensuring broad compatibility. “BDXL” Blu-ray Discs can now store up to 128GB of data, and Ultra HD Blu-ray Discs can hold full-length movies for 4K Ultra HDTVs. Today, except for a single MacBook Pro model that hasn’t been updated since 2012, Macs are physically too thin to accommodate optical drives, and that’s not going to change any time soon.īut optical disc technology has soldiered on, adding new features to hook serious video and photo fans. Citing Blu-ray Disc licensing issues and the growing popularity of Internet streaming, the company was able to leave CD, DVD and Blu-ray drives out of new Macs without suffering any drop in sales. Apple gave up on optical drives several years ago.
