Capacity Difference between USB2.0 and USB3.0 32GB Flash Drives


Recommended Posts


I recently bought a USB2.0 32GB Flash Drive, Model No. CMFVYA32GB. And I also bought another USB3.0 32GB Flash Drive, Model No. CMFVY3S-32GB.


I plugged-in both in my WindowsXP based laptop, but both of them show a slightly different total capacity. The USB2.0 drive shows a capacity of 32,479,637,504 bytes. The USB3.0 drive shows a capacity of 32,094,744,576 bytes.


I am getting about 367Mb less capacity on my usb3.0 drive, even though both are 32GB drives. Can you please explain if this is by design? and why?
