Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times.
AS SSD Benchmark is a straightforward tool for measuring the speed of your SSD drive.
Simply launch the program, choose your drive, click Start, and it'll test your SSD's read and write speed in a variety of ways, delivering a score for each when it's done. And if that's not enough, there are also additional file copy and compression-related benchmarks available from the Tools menu.
Your benchmark results can then be exported in plain text, as an XML file or PNG image, ready to share with others.
But if you'd like to compare your results with SSDs on other systems that you access, then the easiest way is just to unzip the program's download file to a USB flash drive. It's fully portable, so there's no installation required: just plug the USB drive into any convenient PC with an SSD, run the benchmarks, and save the results back to the USB key for analysis later.
