The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system's performance with various transfer sizes and test lengths for reads and writes. Several options are available to customise your performance measurement, including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturer's RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage. ATTO uses RAW or compressible data.
We are using version 4.1 for our NVMe disk tests, with a set length of 256 MB, and testing both read and write performance simultaneously. We are introducing ATTO 5.0, which brings new features, enhancements and changes for more accurate testing of the latest drives.
Using version 4.0.02 of the ATTO benchmark, we couldn't get close to the official read Sequential maximum of 14,000MB/s, with a test result of just over half that at 7,480MB/s. This has nothing to do with the drive; it's down to this version of ATTO and how it deals with the latest Gen 5 drives. A look at the ATTO version 5 results for the drive confirms this.
ATTO 5.0 brings new features, enhancements and changes for more accurate testing of the latest drives. Using this, we were able to confirm and even better, the official maximum Sequential figures with test results of 14,930MB/s and 13,490MB/s for reads and writes, respectively.
