In our tests the Kingston DataTraveler HyperX 3.0 64GB flash drive peaked at 259MB/s read and 149MB/s write with sequential transfers. Random transfers were lower, meaning that the drive has been designed mainly for moving large media files around instead of using this as a system drive.

Real-world file benchmarks scored extremely well. The HyperX drive was able to transfer 9GB of data in less than two minutes and it took just over a minute to transfer 6GB of data.

The five-year warranty of the drive adds piece of mind and we had to complain about something, it would be the drive's rather big size, at least compared with other flash drives. The above-average width would obstruct adjacent ports of your laptop, so that's worth bearing in mind if your laptop's I/O ports are particularly close together.

In case you have more money to spend, Kingston also offers a 256GB of the drive :-)

The good

• Very fast sequential transfer speeds with large files
• High capacities offered ranging from 64GB to 256GB
• Durable design
• Five year warranty

he bad

• Weak random write speeds
• Big size
