Results: Sandra

On Sandra we run the File System Benchmark module and used two parameters, the overall performance (called “index” by Sandra), measured in MB/s, and the random write speed, also measured in MB/s. Usually write speeds are lower than read speeds, so it is also very important to know the write speed, not only the read speed of an USB drive.
