HD_Speed is a simple yet very useful free application for testing the speed of data recording‭ for various devices.‭ It can work with hard disks, optical disks, USB memory sticks and other data media. HD_Speed can work with both logical partitions and the whole disk.‬‬‬

HD_Speed is a portable application, i.e. it does not require installation on a computer.‭ Besides, this program does not use too many computer resources and has a simple UI.‬‬

Key features of HD_Speed:

‭- Tests the speed of recording and reading from different types of devices.‬‬‬
‭- Shows the current and average speed of the storage device performance.‬‬‬
‭- Carries out tests for blocks of different sizes — ‬from‭ ‬16‭ kB to‭ ‬1‭ MB.‭ It is possible to either specify the ‬‬‬‬‬‬
exact block size or use the “floating” mode in which the test is performed for variable block sizes.‬‬‬‬‬‬‬‬‬‬‬‬
‭- Provides an ability to test the peak read/write speed.‬‬‬
‭- Carries out tests in several modes: reading, writing, reading + writing, reading + writing + verifying.‬‬‬
- Provides an ability to save test results to a file.
‭- Shows the number of errors detected during the test.‬‬‬
‭- Visualizes speed changes using a graph.‬‬‬
‭-‬ Provides an ability to display speed in different units: bytes/sec and bits/sec.‬‬‬
‭- It is possible to test both the media as a whole or just certain parts of it.‬‬‬
