QNAP TS-451D2-4G 4-bay NAS Review

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 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.

QNAP quotes Sequential throughput performance for the TS-451D2 as up to 220MB/s for reads and up to 224MB/s for writes with both LAN ports being used in Link Aggregation mode. With a single Ethernet connection (the way we tested the NAS), the official figures are 113MB/s reads and 112MB/s writes which we could confirm with the ATTO benchmark, with an average figure of 116.25MB/s for both read and writes for the five tested arrays.
