Asustor Drivestor 4 (AS1104T) 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 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.

Asustor rates the Sequential (SMB 512KB) read/write performance of the Drivestor 4 as 214MB/s and 266MB/s respectively. These figures were obtained from a Drivestor 4 loaded with four Seagate IronWolf 110 SSDs built into a RAID 5 array. We used 6TB WD Reds to test the NAS and the best figures we got with the ATTO benchmark for a RAID 5 array were 205MB/s for reads and 138MB/s for writes. The fastest speeds we saw were 225MB/s for reads and 272MB/s for writes when the drives were tested in a RAID 0 array.
