Select a drive: Computer users select a local disk or a volume to test its performance.

Step 2: Select a drive and set parameters to test the disk performance. And then click Disk Benchmark on the toolbar. Step 1: Download and launch MiniTool Partition Wizard to get its main interface. Here is step-by-step guide to disk benchmark in MiniTool Partition Wizard. It can not only complete hard drive test but also carry out SSD speed test. MiniTool Partition Wizard is also an SSD benchmark tool. This feature is free for computer users and it displays well the relationship between IOPS and Throughput. The Disk Benchmark feature of MiniTool Partition Wizard is recommended. To help you to comprehend the above two indexes, I will show you how to measure disk performance.

But computer users still can refer to it when they buy a hard drive. The real IOPS of a disk in computer will be affected by many factors. However, the calculation result is a theoretical value.

The IOPS values of common hard drive have already been listed on Wikipedia. The calculation formula is as follows: IOPS = 1000 ms / (seek time + rotational delay time). The disk rotational speed will indicate the seek time and rotational delay. Generally speaking, IOPS can be calculated according to the disk rotational speed. Throughput is the total data transfer volume per second.

To understand the result of the disk performance test, I have to introduce Input/Output Per Second (IOPS) and Transfer Rate (also called Throughput).IOPS is the number of I/O operations per second. To know the specific performance, they need to do a disk performance test.īesides, if a hard disk has served for a long time, computer users can also run hard drive performance test in their computers to know whether it still works well, because even the same hard drive has different performance in specified computer conditions. When computer users get a new hard drive disk, they may want to know the specific performance of the hard drive in their computers.
