USB 3.0 Flash Drive Speed Tests - VID = bda (Realtek Semiconductor Corp.), PID = 301

Welcome to Speed Tests Web site for USB 3.0 Flash Drives/Disks.
In this page, you can find the speed test results of USB 3.0 flash drives or disks, made by USBDeview utility. USBDeview make this test by writing a large file into the USB 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.
