Asustor AS4004T 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 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 AS4004T performs well considering it only has a dual-core processor. The fastest speed we got from the NAS was 611MB/s read speed with a 10GbE connection with the disks built into a RAID 5 array. While the RAID 5 read speed was good, the write speed at 225MB/s was a bit disappointing – as was the RAID 6 write speed.

With a 1GbE connection the NAS performed as you might expect although once again there was a drop in the write speeds of RAIDs 5 and 6.
