I have recently purchased a sandisk ultra 64gb pendrive usb 3.0 and I am not happy with the product performance.

I am getting an average write speed of 6-10 Mbps as against the expected speed of at least 50Mbps (and that’s too bad for usb 3.0 pendrive).

As comparison, My 32GB Sandisk SDCard (Class 4), gives a consistent speed of 7.5 Mbps on Usb2.0 port itself.

Note : I also purchased a 64gb sandisk ultra micro sd card (class 10), it has much better and consistent write speed of avg 15 mb on Usb2.0 itself. It doesn’t start high and then comes down to 7-9 Mbps like this pendrive.

It seems your USB 3.0 drive is underperforming. Try these steps:

  • Make sure you’re using a USB 3.0 port (usually blue).
  • Test the drive on another computer.
  • Run a speed test with a tool like CrystalDiskMark.
