How do you know the speed of the stick

How do you know the speed of the stick

The main characteristics of the stick, or rather the USB-keychain are its capacity and performance.

Under the capacity to understand the stick reading speed and data recording in megabytes per second.

Learn flash speed can be achieved by the pilot to read and write large amounts of data.

You will need

  • flash drive, the computer



The manufacturer indicates the recording and reading speed stick in its specifications on itsofficial website. The recording speed can be more than three times less than the speed of reading. Performance specified in megabits per second at 8 times less than the speed specified in megabytes per second. The interface provides the technical characteristics of flash drives, where you can determine the performance stick. The most common USB 2.0 port. Its maximum transfer rate of 480 Mbit / s or 60 MB / s. In fact, the performance is rarely more than 30 MB / s.


Specified in the technical specificationsproducer read speed and write data does not match the actual, which depends on the computer and on the operating system. To determine the actual speed it is necessary to test the USB flash drive on your PC operating system installed on it. On the flash drive, first write a big file of 600? 700 megabytes, for example, download a movie, and measure the time spent on it. So we define the recording speed. To clarify the rate to be written about ten small files of the same total volume and measure their recording time. Then we can calculate the average speed of the two results and to further orient it. To determine the speed of reading, carry out the reverse operation in the same order: read the large file stick on the hard drive to measure time reading,We read the same amount of small files, and again to measure time. We calculate the reading speed in both cases. The average of these two speeds will indicate the speed of information reading from a particular stick on the computer with the operating system installed on it.


If the received read / write speed stick is insufficient to handle large amounts of data, you can buy keychain with NAND-memory with a higher performance.
