IOMeter & HD Tach


IOMeter is an I/O subsystem measurement and characterization tool for single and clustered systems. It is used as a benchmark and troubleshooting tool and is easily configured to replicate the behavior of many popular applications. One commonly quoted measurement provided by the tool is IOPS.

IOMeter allows the configuration of disk parameters such as the ‘Maximum Disk Size’, ‘Starting Disk Sector’ and ‘# of Outstanding I/Os’. This allows a user to configure a test file upon which the ‘Access Specifications’ configure the I/O types to the file. Configurable items within the Access Specifications are Transfer Request Size, Percent Random/Sequential distribution, Percent Read/Write Distribution, Aligned I/O’s, Reply Size, and TCP/IP status among others.

HD Tach

HD Tach is a program that tests the sequential read, random access and interface burst speeds of the attached storage device (hard drive, flash drive, removable drive etc.). Drive technologies such as SCSI, IDE/ATA, IEEE 1394, USB, SATA, and RAID are all supported.

Version is sadly the final version and the software has reached its end-of-life support. It’s still a nifty benchmarking tool and it can’t hurt to include it in our tests.
