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.
240GB MyDigitalSSD ATTO Benchmark Results
The MDM242-SB-256 m.2 drive provided to Benchmark Reviews for testing produced 545 MBps maximum read speeds that plateau when the file size reaches about 256KB, and 431 MBps peak write bandwidth that plateaus starting at 64KB. Both of these numbers meet or exceed the specs for this drive, which are 545MB/s for reads and 410MB/s for writes. While the sequential write speeds are a little below state-of-the-art, the read speeds are very good:
In the next section, Benchmark Reviews tests sequential performance using the CrystalDiskMark 3.0 software tool…
