The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize 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 manufacturers 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.
The results from the ATTO benchmark shows that it doesn't matter what type of drive mix you use, the BeyondRAID technology in the Drobo 5N2 builds them into effective arrays, all of which topped 100MB/s for reads and writes.
Why didn’t you do the benchmarks with link aggregation enabled? The 5N2 has 2 gigabit LAN ports. This is one of the main reasons anyone would want to upgrade.
