USB Flash Benchmark is a plain and simple speed testing program for USB flash drives. Comparing results is very important to see whether your devices are working properly or not. The community is pretty big, so it’s easy to find similar devices to yours. You can also share your results with the community. You can see the result in real-time and after it’s done, you can save the results. Select your drive from the drop-down list, and run the kind of test you want. If you have a faster drive, try increasing the setting to 500MB/1GB. Running the test for your USB drives shouldn’t take long at all. CrystalDiskMark is designed for much faster devices that can satisfy many enthusiasts, so it can be very powerful. You can choose either portable, installer, or themed versions of the software.īefore you run the test, we recommend that you drop the default test size to 50MB/100MB and the number of passes to 1 or 2 for slower USB drives. It can be used to test the performance of hard drives, SSD, and USB drives. CrystalDiskMark is probably the most famous USB tool to measure sequential and random performance (Read/Write/Mix).
