AS SSD Benchmark is a free, portable utility for measuring solid-state drive performance. It tests sequential read and write speeds, input/output operations, and response times, then displays a score for each test. Additional file-copy and compression-related benchmarks are available from the Tools menu. Results can be exported as plain text, XML, or PNG. No installation is required, so it can also run from a USB drive.

AS SSD Benchmark is a free, portable utility for measuring the performance of solid-state drives. It is intended for SSD owners who want to check how quickly a drive reads and writes data, assess its response and input/output performance, or compare results across different systems. The program runs directly without installation, making it suitable for occasional checks as well as testing several computers from a USB drive.
The main benchmark measures sequential read and write speeds, showing how quickly the drive transfers data in larger, continuous blocks. It also tests input/output operations and access times, which help indicate how the SSD handles smaller requests and how quickly it responds. To run a test, the user selects a drive and starts the benchmark; AS SSD Benchmark presents a score for each test when it finishes. These results offer a practical way to compare storage performance under the same testing method.
Additional tests are available from the Tools menu. The file-copy benchmark measures how the drive performs when copying data, while the compression-related test examines speed with data that can be compressed to different degrees. These workloads provide context beyond sequential transfer rates, since everyday tasks often involve copying files or working with data in varied formats. Results can be exported as plain text, XML, or a PNG image for record keeping or sharing.
The utility can be used to check a newly installed SSD, investigate whether a drive is performing as expected, or compare storage devices in systems the user can access. Because it is portable, it can also be kept on a flash drive and run on another compatible computer without a setup process. Saving results to the same USB drive makes it easier to review measurements later or keep a simple record of tests from multiple machines.
AS SSD Benchmark is freeware for Windows. Its workflow is deliberately direct: choose a drive, run the tests, and export the results if needed. Benchmark scores are most useful when compared under consistent conditions, so results from different systems or test runs may vary with hardware and system activity. The tool focuses on SSD performance measurements rather than general system diagnostics.
