Type C USB C to Micro B Cable External Hard Drive Cord For WD Westgate iPhone 3m [Product Features]: Full duplex data transmission. In USB 3.0, in addition to the 4 main lines, two sets of cables are added (each set has a pair of signal lines and ground lines, wrapped in aluminum foil for shielding, and do not interfere with each other). One set is used to send data and the other set is used to receive data. This means that USB 3.0 can perform read and write operations synchronously at full speed. Previous USB versions did not support full duplex data transmission. Ultra fast transmission speed, USB 3.0 is also known as SuperSpeedUSB, greatly increasing bandwidth, up to 5Gbps full duplex or 625MB/S, but the actual transmission rate is about 3.2Gbps, or 400MB/S, while USB 2.0 is 480Mbps half duplex, or 60MB/S. USB 3.0 can transfer a large number of files (such as high-definition movies) at the storage rate limited by the storage device. For example, a flash drive using USB 3.0 can transfer 1GB of data to a host in 15 seconds, while USB 2.0 takes 43 seconds. Supports USB 3.0 (5Gbps), compatible with USB 2.0 (480Mbps) and USB 1.1 (12Mbps) specifications. Supports Windows 2000/2003/XP/Vista/WIN 7SP1 and Linux Apple IOS.
