The Thunder Drive is the fastest, smallest, and most reliable external drive for Thunderbolt 3, USB C, and USB. It works with any PC or Mac and is designed not only to provide additional storage but to make your computer faster. The biggest limitation in most computers is the hard drive speed and this is the easiest way to upgrade it. It features two ports for linking drives to give you additional speed. This means just two drives can deliver up to 2,000GB at 1,100MB/s.
