USB Flash Drive Speed Tests - VID = 4b4 (Cypress Semiconductor Corp.), PID = 6830

Welcome to Speed Tests Web site for USB Flash Drives.
In this page, you can find the speed test results of USB flash drives, made by USBDeview utility. USBDeview make this test by writing a large file into the USB flash drive, and then reading back the same file to getting the read speed. The speed is calculated and displayed in Megabytes per second (MB/Sec). Be aware that all these tests are made by making a sequential read and write operations of a single file. When you use multiple small files, you'll probably get much lower read/write performances.

If you want to test the read/write speed of your own USB drives and share the results with other people, you can follow the instructions in this page: Test and publish the speed of your USB flash drive.

There is also a summary page, which contains a summary of speed tests for USB drives that accumulated 5 speed tests or more.

Some Remarks

To more easily compare the speed of USB flash drives, you can filter the list according to drive size group:

1 GB or less 2 GB Group 4 GB Group 8 GB Group
16 GB Group 32 GB Group 64 GB Group Larger than 64 GB

Notice that the USB devices of last size group (above 64 GB) are not really flash drives. they are external hard disk drives plugged to USB. I originally created this Web site for flash drives, but because some people already submitted the speed test results of external USB disks, I added a group for them too.
