Test USB Flash Drive Read & Write Speed With Graph Plotting

To gauge the optimal read & write speed of your USB Flash drive sometimes become a hassle because there is a lack of requisite tools and softwares on the internet. Normally the data transfer rate varies drastically during our operations on the PC, sometimes you will observer a data rate of almost 25 MB and in some instances it might drop down to almost 2 MB.

I guess that checking the optimum potential of the read & write speed of your flash drive is quite worth doing because this process can determine that what other PC processes running at back end are hampering your flash drive read & write process. So recently I tried a very useful application that will very much solve this issue, have a brief look at it:

In the following table, you can find a summary of speed tests sent by the users of USBDeview utility, for USB drives that accumulated 5 speed tests or more. Each line in this table represents the combination of device name, VID, PID, and rounded drive size (‘USB Drive Details’ columns).
Here’s some more remarks about this table:

  • All read/write speed values are displayed in MB/Sec.
  • Very low speed values and very high speed values were removed from this summary, assuming that these test results were erroneous.
  • The ‘drive size’ in table is rounded to the nearest integer value. The drive size displayed in this table is not always the offical valueGB.
  • The ‘Tests Count’ column displays the number of tests that the users sent for this specific USB device. When this number is higher, the average values of read/write speeds should be more reliable.

Select your USB drive from the Drive drop-down menu and click Benchmark to begin testing the USB read and write speed.

This will start generating a graph according to your USB’s read/write speed and present you with a conclusive numerical and graphical representation of the test result. The Read rate is displayed with a green line, whereas, the write rate is displayed as a red line. Benchmarking is shown in a list on the main interface. The result can take up to 20 minutes for completion so make sure that you do not cancel the test. Once the test is complete, you will be able to determine the precise read and write rate of your pendrive according to the amount of data being transferred.

Once the test is completed, a URL will be provided for viewing the details of your test results on the developer’s website.

You can also check out the various USB types and their calculated speeds to determine your USBs read/write rate without even having to go through the benchmarking tests, provided results for your USB model is available
The result on the developer’s page will provide you with a summarized version of the benchmarking result including the USB model, serial number, manufacturer’s name, file system, as well as the read and write speed.

USBFlashSpeed works on Windows XP, Windows Vista and Windows 7.
