describes it, "To become certified, a USB drive must pass a battery of certification tests, as well as undergo self-hosting across a variety of PCs to test-drive for high performance compatibility with Windows 8.1 and Windows To Go. Additionally, certified drives must:
- Be built for high random read/write speeds and support the thousands of random access I/O operations per second required for running normal Windows workloads smoothly.
- Have been tuned to ensure they boot and run on hardware certified for use with either Windows 7 or Windows 8.1.
- Be built to last. Certified drives are backed with manufacturer warranties and should continue operating under normal usage."
