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.
Synology quote throughput figures for the DS918+ at up to 226MB/s for reads and 222MB/s for writes but this is with both Ethernet ports being used in Link Aggregation mode. With a single Gigabit connection we got an average of 118.8MB/s for reads and 115MB/s for writes. The write average was lowered by the drop off in performance when the disks were in a RAID 5 array.
