Vdbench!

CrystalDiskMark is a small HDD benchmark utility for your hard drive that enable you to rapidly measure sequential and random read/write speeds.

Disk Speed Test is an easy to use tool to quickly measure and certify your disk performance for working with high quality video! Simply click the start button and Disk Speed Test will write test your disk using large blocks of data, and then display the result. Disk Speed Test will continue to test writes and reads from your disk so you can evaluate both performance and readability over time.

As the Iometer Users Guide says, Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 - since then it got wide spread within the industry.

A feature-rich and versatile storage testing tool, Diskspd (version 2.0.17) combines robust and granular IO workload definition with flexible runtime and output options, creating an ideal tool for synthetic storage subsystem testing and validation.

SQLIO is a tool provided by Microsoft which can also be used to determine the I/O capacity of a given configuration.

CCSIO Bench measures the maximum possible read/write speed for a given file system location, including local volumes, virtual drives and remote shares. In plain terms, it measures how fast one can possibly read/write very large files from/to specified location.

IOzone is a filesystem benchmark tool. The benchmark generates and measures a variety of file operations.

2U load generation appliance, also runs under a VM, A leading commercial performance validation product for networked storage infrastructure. We help companies reduce risk and save millions of dollars by aligning storage deployment decisions to application workload performance requirements.
