Test System

The following are the crucial system specs for this test.



When testing the drive we wanted to evaluate the general speed of the drive under a couple of different conditions. As many users are still without USB 3, especially in a corporate environment, we also felt that testing the potential of the drive under USB 2.0 was important. Ideally a fast USB 3.0 drive should max out the available bandwidth of USB 2.0 - 480Mbps or 35MB/s theoretically - rather than only show an improvement under optimal conditions.

USB 3.0

The Maximum theoretical bandwidth of USB 3.0 is 5Gbps (625 MB/s); under the most common data encoding parameters this figure drops to ~400MB/s, still dwarfing the spec limits of the Datatraveler HyperX 3. Though the absolute maximum data transfer rate for the drive under reasonable conditions is generally of primary importance, it's also sensible to capture the performance with small file sizes and IOPS to allow a detailed comparison with other USB 3 drives and usage scenario's.

For now, we only have the facility to test the drive in relative isolation and against previous generation USB 2.0 drives. Over time we hope to have the opportunity to increase the data pool by testing additional thumb drives.

USB 2.0

Here, all we wish to test is the speed of the drive in relation to more affordable USB 2.0 drives, and assess whether it can make the most of the 35MB/s available in this configuration. We will be comparing the DataTraveler HyperX 3.0 to a Kingston 8GB DataTraveler SE9, which has fairly typical specs for USB 2.0 flash drives.

Testing Notes:-

1. Poorly configured or malfunctioning USB 3.0 ports may not recognise USB 3.0 devices, but still work in USB 2.0 mode for USB 2.0 devices. Do not assume that the drive is at fault if this occurs, especially if other USB 3.0 devices have yet to be tested.

2. For reasons unknown, some USB 3.0 ports may be limited to ~135MB/s read/write operation. Though not an issue for most drives, external USB 3.0 SSD enclosures and flash drives which are capable of greater speed will suffer.

3. The DataTraveler HyperX 3.0 comes pre-formatted at FAT32, allowing file sizes up to 4GB. In order to test with larger files, we re-formatted the drive as NTFS.
