Review: Transcend USB 3.0 SD/MicroSD Card Reader

0

I recently ordered this Transcend USB 3.0 SD Card Reader to replace the generic microsd reader I have been using for a while. To compare the two I have reran the benchmarks for the 2 microsd cards I have already benchmarked. The updated results are much better, at least for the sequential and 512KB random read speeds, but there are also small gains in a few other areas of the benchmark.
