Even if you do not need more storage for your PC at this time, you may want to consider one of these Western Digital Amazon offers, as we do not know how long they will last. Today Amazon is selling the 10 TB My Book Desktop WD external hard drive for $ 80, 73 percent of its price and the MyTubport unit of 4TB for $ 55 , 65 percent discount and below the low previous price of $ 90.
Our big fans of the Western Digital units here at PCWorld, named WD My Passport as our favorite external backup unit. Like that unit, My Book also uses USB 3.0 and comes with 256-bit AES hardware encryption for confidential files. They are also loaded with the excellent suite or software of Western Digital. You can also use them with a Mac, but first they must be reformatted.
The last time we highlighted these disk drives, they were almost double, so you have a good idea or how crazy they are. At the time of this writing, both were pending delivery for a week, but even if you have to wait to get them, they are still worth it.[[[[Today's offers: 10TB Wd My Book for $ 80 and 4TB WD My Passport for $ 55 on Amazon]
