Performance: h2benchw 3.12

h2benchw was written by Harald Bögeholz, senior editor of the German magazine c’t, and has been our primary hard drive benchmark program; you can find the latest version for download on the c’t website (currently version 3.12). It is a command line tool that outputs a text file with test results. We consider this design a huge advantage, as we typically create batch files to automatically benchmark several hard drives, or to run benchmark sequences on one of multiple drives, according to our needs.

The benchmark tool requires a blank hard drive without any physical partitions. You simply open a command window and execute the file to get an overview of the benchmark options. For a regular hard drive review, we have the tool run all of the benchmarks, and we also include write tests. This requires the tool to be executed with the parameters –a (all tests) and -! (to enable write testing) and we add the parameter –w plus a file name, so the program writes all results into a results file. The command has to conclude with the physical drive number, which are numbered starting with 0. So if the test drive is the third drive, we execute “h2benchw –a -! –w testfile.txt 2”.

We use the text file to create a data transfer diagram for read and write operations (not shown above), and also use most of the other numbers that the benchmark provides. h2benchw provides results for typical application scenarios, such as the swapping RAM data into a swap file, installing software to the drive, running applications, copying data from and to the same drive, and a simulation of the F-Prot anti virus tool. However, we decided to use PCMark Vantage’s HDD benchmark, as its test suite is more up to date. h2benchw also returns read and write access time (Zugriffszeit) and various technical parameters, which may be helpful.
