While real world benchmarks are a better look at what you can expect to get out of a product, synthetic ones are good for quotable numbers and the reliability of repeatable tests.
So for our Synthetic tests, we ran the HyperX Savage 128GB USB through CrystalDiskMark and the Atto Disk Benchmark. Each test will be performed twice via USB 3.0 and 2.0 to ensure accuracy.
As you can see, this batch of synthetic tests shows that the Kingston HyperX Savage 128GB USB drive has very close performance to what is advertised on the box over a USB 3.0 connection, which is very impressive.
USB 2.0 performance is limited, with speeds hovering just under the 45 MB/s mark for both read and write. This is quite the performance hit compared to USB 3.0 but should still hold up well against other USB 2.0 drives.
The ATTO Disk Benchmark performance measurement tool is only compatible with Windows. It essentially measures your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. You can use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives.
Our ATTO results remain consistent across both tests, showing very high read speeds with lower writes in comparison. This test was performed on USB 3.0.
