Seagate's most recent portable storage products are named Backup Plus, recognising the importance of this fact. Oddly, of the two products we have in for review, one is rather unsuitable for backing up data to. The good thing is users have a choice between safety and speed. We put both to the test, to help buyers decide which one is better suited to their needs.While the Backup Plus Slim is pretty much a basic drive in a very small enclosure, the Backup Plus Fast is actually two drives sandwiched into one body. Of course, the two are very different in terms of weight and portability, but they're intended for very different buyers.High-speed USB 3.0 and 2.0 connectivity offers plug-and-play functionality on your PC without the need of an external power supply.Slim is an easy way to protect and share your digital life. Ready to go with 2TB of storage space for your most important files, it also features a sleek and protective metal finish in classic black.
