Even if you do not need more storage for your computer right now, you might want to consider grabbing one of these Western Digital Amazon deals because we do not know how long they will be. Today, Amazon WD 10TB sells My Book Desktop External Hard Drive for $ 8073 percent of list price and 4TB My Passport for $ 55 ] 65 percent of and far below the previous low price of $ 90.
We're big fans of Western Digital devices here at PCWorld and name WD My Passport as our favorite external backup device. Like this device, My Book also uses USB 3.0 and comes with 256-bit AES hardware encryption to store sensitive files. They are also loaded with Western Digital's excellent suite. You can even use them with a Mac, but they must be reformatted first.
The last time we checked these units, they were almost twice as much, so it gives you a pretty good picture of how insane they are. When writing this, they were both re-ordered with a week, but even if you have to wait to get them, they are still worth it.
