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


• Quick and easy to use


• Compact main window


• Clear-cut UI with detailed information

Technical Specifications:

• Total of 300 tests (180 read tests and 120 read tests)


• Each test takes about 1 second to complete


• Benchmarks completed in 5-6 minutes


• Results displayed as graphs


• Raw data mode for detailed view

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, which offers a more pragmatic and thorough view of all the benchmark details.

For your convenience, the application also makes it possible for you to view test reports, save the reports, or share screenshots with the visible results.

CCSIO Benchmark proves itself to be a fairly well thought-out utility, capable of helping you accurately measure how fast your computer's disks (volumes) can actually read and write very large files, all with just a few mouse clicks.
