ATTO Disk Benchmark
The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.
256GB Transcend ESD400 ATTO Benchmark Results
Although the results are much faster than those from an external USB-powered hard drive, the Samsung is still relegated to the very bottom of the chart for this benchmark. However, note that in this benchmark the maximum read speed of 456MB/s exceeds Transcend’s specification of 410MB/s, while the maximum write speed of 341MB/s is slightly less than the 380MB/s spec.
