SCSITool - NEW
A very comprehensive diagnostics and benchmarking tool for SCSI storage devices. Currently supported device types are: harddisk, tape, cd-rom, optical and removable disks. Learn more about the SCSITool and download the program by following the link above.

RAIDmark
The only benchmark we have found that was specifically created to measure the performance of RAID arrays. RAIDmark benchmarking program by DynaTek Automation Systems Inc., measures cache size, system overhead, and application-level performance. Includes MS-DOS and Novell versions. Unfortunately, the source code is not included. As far as we know, this was the last release of RAIDmark; DynaTek no longer supports or does any development of this benchmarking program.

Qbench
DOS hard disk benchmark from Quantum Corporation which measures data access time and data transfer rate. Just a nice little benchmark for quick results. No source code included.

COREtest
DOS disk benchmarking program created by CORE International. CORE Disk Performance Benchmark is distributed as a DOS binary, no source code included.

		UNIX Windows DOS

		Please note that we have only collected benchmarks for measuring I/O performance. There are tools available for benchmarking various other system components. Very often, it is very hard to get objective I/O performance results from your storage vendor. They use proprietary benchmarks or their benchmarks get tuned to their particular storage device. This makes it very hard to compare different products from different vendors. To overcome this, you can download one of the benchmarks for "open systems" we have here and then run it with different vendors' storage devices. This will give you results which can be compared against each other, thus giving you an opportunity to buy a storage solution that is right for YOUR company. A word of caution. You can get great I/O performance results as indicated by one of the benchmarks but in a REAL APPLICATION environment at your company, the performance can be not at all up to par. If at all possible, always try to test a storage device offered to you in YOUR APPLICATION environment. DON’T just rely on benchmark results! We hope you will find these benchmark programs helpful. Please check this page often because we will add more I/O benchmarking programs as we find them. If you would like to send us the results of running any of the above benchmarks on your hardware, please feel free to do so. We will post the results here when we get an adequate number of responses.
