The moral of the story? If you want great portable hard drive speeds, USB 3.0 is the only way to go! ATTO Disk Benchmark had a write of 30.8 and a read of 30.5. As you can see from the results below via USB 2.0, the speed drops almost by 100 with the read speed 30.46 and write speed of 30.60 (CrystalDiskMark). The performance does drop considerably when using USB 2.0 but this is not a product issue but rather the limitations of the USB 2.0 interface.

We also tested the drive with ATTO Disk Benchmark and the drive scored speeds of 134 Write and 130 Read which mimicked the results of CrystalDiskMark. In terms of performance, the drive performed well with a Sequential Read speed of 132.0 and a Sequential Write speed of 131.0 thanks to CrystalDiskMark, a popular benchmarking tool. No installation of the drive is required as it is preformatted with the NTFS file system so you basically just connect it to your PC or Mac.
