Hey everyone,

I just bought a Sandisk Ultra Fit 64GB USB 3.0 flash drive.

I highlighted everything on my desktop and dragged it into the flash drive window. In total it is about 36GB.

It takes about 4 hours for the flash drive to write that 36GB.

I have it plugged into a 3.0 port on my Lenovo Edge e330 laptop.

The computer says the USB is 3.0 connected.

It just seems like this is a hell of a long time for a supposedly super speed flash drive to write 36GB. Or is it not?

Thanks for your advice.

That would put it at about 2.5MB/s, which is pretty slow, even for a USB2.0 drive.

Where did you buy it? Are you sure it's genuine?

I bought it from a major retailer here in Australia.

First you should check that the port you are using is actually working as USB3. Remember that a USB2 device on the same branch of devices can slow other things down to usb2 speeds- things lik your mouse are usb2 so put it onto a USB2 port- there's no advantage using a usb3 port and possible disadvantages. The device manager will tell you if it's working properly or not.
