CCSIO Benchmark

CCSIO Benchmark (short for Cold-cache Sequential I/O Benchmark) is a simplistic yet useful utility that helps you accurately determine the maximum speed you can read or write bulky files to and from various locations. What's more, this featherweight utility can also be employed to help determine the read/write performance of systems running on shared remote drives and even virtual devices (encrypted file containers and RAM disks).

Key Features:

• Does not require installation


• No need for full administrative rights


• Simple download and launch via executable file


• Compact main window with clear UI


• 300 benchmark tests (180 read tests and 120 write tests)


• Test completion in about 1 second


• Automatic skipping of tests exceeding 64 MB limit

Viewing Results:

Once a benchmark test is completed, you can view the results (read and write speeds) within their designated sections, displayed as graphs on the lower part of the main window. There's also a raw data mode, offering a more detailed view of all benchmark details. Additionally, the application allows you to view test reports, save them, or share screenshots with visible results.

Taking everything into account, CCSIO Benchmark proves to be a well-thought-out utility, capable of accurately measuring how fast your computer's disks can read and write large files with just a few mouse clicks.
