One of the good things about USBDeview is it’s still actively supported and updated.įind your USB device which should be highlighted in green with a device type of “Mass Storage”, right click on it and select Speed Test (Ctrl+T). Another feature is the option to benchmark a flash drive and optionally publish the results to the Nirsoft Speed Tests webpage for viewing and comparison. USBDeview is a portable utility by Nirsoft that lists or allows you to uninstall current and any previous USB devices attached to your computer. Here’s a selection of 8 free tools to benchmark your USB flash drives or media cards to give you an idea of how fast they are. If you buy a slow USB flash drive with a high capacity, it could literally take hours to fill it up completely.īut if you already have some USB flash drives in hand, do you know how fast they actually are at reading and writing? A drive that only writes at 5-6MB/s could take a while to copy large files like movies, whereas a fast USB3 flash drive could do the same copying tasks much faster.

With hard drives and SSD drives, you will be looking at capacity and read/write speeds, and it’s a similar story when you purchase a removable memory card or USB flash drive.Īpart from having to worry about USB drives being the full capacity and not being fake if you buy from somewhere like eBay, the performance of a flash drive can vary by massive amounts depending on manufacturer and the type of memory used.

Whenever you buy a new piece of computer hardware, whether it’s a CPU, memory, hard drive etc, one of the factors that will help to determine your purchasing decision would be the performance of the component.
