CrystalDiskMark is a small HDD benchmark utility for your hard drive that enables you to rapidly measure sequential and random read/write speeds.
1000MB Files Test Benchmark on the HGST TOURO Pro 500GB:
The HGST TOURO Pro was able to reach 122 MB/s read and 62 MB/s write in the sequential test. Not bad performance numbers from a 7200 RPM notebook hard drive, but we are clearly limited by the hard drive and not the USB 3.0 interface with these test results.
ATTO is one of the oldest hard drive benchmarks that is still used today. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that you can easily interpret. The benchmark was run with file sizes from 0.5kb through 8192kb with the total length being 256mb.
Benchmark Results: The HGST TOURO Mobile Pro 500GB USB 3.0 external hard drive was able to reach 125 MB/s read and 126 MB/s write in ATTO. The WD My Passport Edge 500GB USB 3.0 drive that we reviewed last year was hitting 123 MB/s read and 120 MB/s write, so the performance of this drive is solid.
