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.
In Sandra ATP ToughDrive 1 GB also has achieved the best reading performance, being a little bit faster (3.45%) than Patriot Xporter XT 2 GB and Geil David 100 256 MB, which achieved the same performance level. It was 30.43% faster than OCZ Rally 2 GB and 36.36% faster than OCZ Rally 512 MB.
As for writing performance, ATP ToughDrive 1 GB also achieved the best result, being 7.14% faster than OCZ Rally 2 GB, 25% faster than Patriot Xporter XT 2 GB and 50% faster than Geil David 100 256 MB. Here Patriot Xporter XT 2 GB was 20% faster than Geil David 100 256 MB.
