DiskTester™ 2.0 Information Page
WelcomeDiskTester™ measures disk performance, especially RAID setups. But it can also be used for testing digital camera cards, network performance, or comparing single-drive performance with SATA, FireWire and USB. Its sophisticated testing approach offers the most consistent and reliable results available today. Disktester is used for internal testing by several manufacturers of RAID and SATA hardware cards to test their products as well as performance-review sites (see below). If you’re a digital photographer, sooner or later hard disk performance will become an issue for you. Don’t miss the diglloyd.com blog, which usually discusses photographic issues, but regularly provides tidbits on hard drive setup and performance. How does DiskTester work? Please see the DiskTester User Manual for complete details. See also example output for all the commands and the software license. If a command-line interface makes you uncomfortable, please see Command Syntax Primer. DiskTester is not limited to testing RAID setups; it can test digital camera storage cards and network drives, too. Utilized by performance-review site barefeats.com DiskTester is frequently used by the popular Macintosh performance test site barefeats.com, which began using DiskTester when it was first released. To date, a number of performance reviews at barefeats.com have used DiskTester“Though DiskTester lacks GUI and must be run via Terminal, it has turned out to be an invaluable tool for simulating capture and playback of DV footage”—April 15, 2005 "Speed Tests". Here are various performance reviews at barefeats.com which have used DiskTester (partial list, there are many, many more reviews using DiskTester as of June 2008): Sonnet’s PCI Express SATA Host Adapter with Port Multiplication Fibre Channel VideoRAID from Medea Sonnet Tempo-X eSATA 8 Port External PCI-X Host Adapter HighPoint RocketRAID PCI-X host adapter TransIntl's SwiftData 200 Puts 5 Drives INSIDE A G5 Power Mac What Set of Four SATA Drives Creates The Fastest RAID 0 (striped) Set?

FAQ (frequently asked questions)Is DiskTester a 64-bit application? No. The 64-bit version (we’ve built one) offers no testing advantage whatsoever over the 32-bit version and is a much larger binary. What makes DiskTester the best choice? DiskTester has proven itself over several years as offering consistent and reliable testing results. Pretty graphs don’t cut it—only solid results you can trust. What other features does DiskTester have? Aside from performance testing, reliability is critical. We recommend that all users setting up “production” systems run a full 24-hour reliability test with DiskTester. Testing your system with the asynchronous I/O test is also a good idea (run-async-test). DiskTester can also create and read hieararchies of files and folders—a great tool for testing real-world performance with repeatable results. For example, a file hierarchy can be created, and then Finder-copy and backup tests performed. Or you can use DiskTester to test that file hierarchy directly. Finally, disktester can “dump” information about all your mounted volumes in convenient text form for diagnosis and analysis.
