Asustor AS5202T Nimbustor 2 2-bay NAS Review

We tested the AS5202T with a number of scenario’s that it may face in the real world. The settings for these scenarios are as follows.

File Server
512MB file size, 16KB Block size, 80% Read 20% Write 100% Random, I/O queue depth 128

Web Server
1GB file size, 16KB Block size, 100% Read 0% Write 100% Random, I/O queue depth 64

Workstation
1GB file size, 16KB Block size, 70% Read 30% Write, 50% Random 50% Sequential, I/O depth 1

Database
2GB file size, 4KB Block size, 90% Read 10% Write, 90% Random, 10% Sequential, I/O queue depth 128

Media Streaming
160GB file size, 64K Block size, 98% Read 2% Write, 100% Sequential, Boundary: 4K, I/O depth 64, Threads/Workers: 8

The Asustor AS5202T displays strong performance in our workload scenarios, even when it's using the 1GbE connection. The best figure we saw from the tests was the 340.87MB/s for the File Server test with the disks built into a RAID 1 array, using a 2.5GbE connection.
