What are the recommended benchmarking tools for measuring Drobo performance?
Our recommendations for benchmarking tools include: For Windows systems: • HD Tune is a good benchmarking tool. Go to hdtune.com to download the latest version. For Mac systems: • We recommend the Kona benchmark tool. This is available under AJA “Kona System Test” at http://www.aja.com/support/kona/kona-3-3x.php • We do not recommend the XBench tool. Research into XBench has revealed a decidedly critical and negative view of this software as a reliable benchmark. • To measure (or view) Drobo performance (in real time while Drobo is actively being used) use OS X’s “Activity Monitor” as a reliable means of measuring drive performance. Select the specific drive under “Disk Usage,” then choose “Disk Activity.” • Use OS X’s Terminal application and the “dd” command as a means of measuring Drobo performance. Example: “dd bs=4096 count=262144 if=/dev/zero of=/Volumes//junk_1GB This command will create the file “junk_1GB” on Drobo and then fill it with 1GB’s-worth of zeroes, in 4KB blocks. It
