The sleek design features a sliding USB connector, which smoothly extends from the drive at the push of a thumb. The capless mechanical design eliminates the hassle of lost drive caps. The USB connector can be made ready for use with just one hand, for greater convenience when speed is a must. USB 3.0 High-Speed Transmission Interface. The USB 3.0 interface implements dual-channel transmission mode to deliver read speeds as high as 40MB/sec, and write speeds up to 25MB/sec, while retaining full backward compliance with USB 2.0 ports.
