The most important factor in determining the maximum data transfer rate of card readers is the device's USB standard. The descriptions for MAXGO MG-3004 model usually say USB 2.0 based. This means a maximum speed of 480 Mbps (approximately 60 MB/s) in theory. But in practice, due to the class of the memory card used (e.g. UHS-I, UHS-II), the device's internal controller, and the quality of the connection, speeds are usually lower, often around 20–30 MB/s. Comparative Look Features USB 2.0 0 Card Reader (MG-3004) USB 3. 0 Card Reader (Alternative) Theoretical Max. Speed: 480 Mbps (~60 MB/s) 5 Gbps (~625 MB/s) Realistic Average: 20–30 MB/s 80–100 MB/s (dependent on card class) Suitability: Everyday use, small file transfers Professional photo/video, high-resolution files Recommendation: If you're only transferring small files (photos, music, documents) via phone/tablet, the MG-3004 should be sufficient. • However, if you are working with high-resolution photos or 4K video files, it is much faster and more efficient to choose a card reader with USB 3.0 support.
