Map tested with CrystalDiskMark 3.0.1 x64. Transfer speeds are substantially equal when the memory is placed in the USB media provided or in a SDcard support. The results are (in MB / s): Sequential Read: 19.2 11.3 Write, Random Read 512KB: 18.9 0.8 Write, 4KB Random Read (QD = 1): 0.009 4.4 Write, 4KB Random Read (QD = 32) 4.4 Write 0009 MB / s. So "correct" rate for large files, the catamaran for small files. Worse than a cheap key noname purchased in supermarkets there 2 years (test on same machine). The included drive is small, but the flared part, certainly aesthetic embarrassment to the establishment of another USB stick side. Fortunately, it is possible to shave a bit this flared part because it is only the body.
