The 2TB will hold 1792 x MP4 movies, more than 70 hours of 4K compressed movies, 512,000 x 12MP images, and 531,344 x MP3 songs. There is also a 1TB version.
It uses a zinc-alloy case for durability, is 72mm x 26.94mm x 21mm, and has a 5-year warranty. At its release in February it will have the full-size USB A connector – USB-C users (like Mac owners) will need an adaptor but that should not affect read/write speeds.
USB 3.1 Gen 1 offers the same ease of use and plug-and-play capabilities as previous generations of USB, but with a 10X performance increase and better power management.
In theory, it can achieve up to 5Gbps (practical speed 300-350MB/s) compared to 480Mbps (35-40MB/s) on USB 2.0.
