The product images explicitly detail a "Real Test" result, indicating an average write speed of 18.02 MB/s and an average read speed of 21.50 MB/s. These figures are entirely consistent with the expected performance envelope of a USB 2.0 interface, which possesses a theoretical maximum bandwidth of 480 Mbps, translating to approximately 60 MB/s in ideal conditions. Actual speeds vary based on many factors.
The real-world impact of these transfer speeds depends heavily on the characteristics of the files being moved, specifically their size and quantity. The provided test results illustrate this: transferring 100 photos, each approximately 2MB, takes 10 seconds, while 100 MP3 files, each around 6MB, require 30 seconds. A critical, transparent warning on the product image states, "Small files will seriously slow down the transfer speed!" This insight is vital for managing user expectations. Users must understand that transferring numerous small files, a common scenario with document backups, email archives, or image thumbnail libraries, will not achieve the peak speeds observed with larger, contiguous files. This can lead to frustration if expectations are misaligned.
Compared to modern USB 3.0 or USB 3.1 card readers, which are engineered to offer significantly higher speeds, often upwards of 100-300 MB/s, the Kebidumei reader operates at a more modest pace. This speed difference represents a logical trade-off, balancing its affordability and its broad compatibility with older computer systems that may not feature newer USB standards. For routine backups of personal photos, school documents, or small project files, USB 2.0 speeds are often entirely sufficient. However, for professionals regularly transferring massive video files, extensive RAW image libraries, or large software installations, the slower speed could undeniably become a significant bottleneck. Patience is required for larger transfers.
