WD My Book Studio 2TB USB 3.0 HD

As a writer, I always have a number of books and magazine articles in various stages of preparation. Those pending publications represent years and years of future income, so I can't afford to lose those files. While the MAC version of My Book Studio is more expensive than the plastic-cased My Book of the same capacity, its aluminum case dissipates heat more efficiently, and keeping the drive cooler should improve the reliability and lifespan of the drive. Moreover, the aluminum-cased drive has a longer warranty. A few bucks extra isn't much to pay for better security. I use one drive for Time Machine backups, and additional drives for manual backups using PROSOFT Data Backup software, rotating these extra drives on a schedule so that a recent backup is in a bank vault, another backup is in a fireproof vault at home, and a third is in my office. I also back up to a cloud service. When a decade's worth of pending income is on my computer, not to mention a treasure trove of family photos, a secure and redundant backup system is essential. The BIG TRUTH here is that anything worth backing up is worth backing up at least twice. I have learned this the hard way. Moreover, those backups should be made on the highest quality drives one can find. That's the My Book Studio for MAC. If you use a PC rather than MAC, it's easy to reformat this drive for your PC.
