Asustor Drivestor 4 (AS1104T) 4-bay NAS Review

We tested the Drivestor 4 with a number of scenarios 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
Transfer Size: 8K Reads: 80% Writes: 20% Random: 80% Boundary: 8K Outstanding IO: 64 Threads/Workers 4

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

Mail Server
80GB file size, 32K Block size, 58% Read 42% Write, 95% Random, Boundary: 4K, I/O depth 64, Threads/Workers: 8

Digital Video Surveillance
160GB file size, 128K Block size, 100% Read, 100% Random, Boundary: 4K, I/O depth 512, Threads/Workers: 8

We also tested the NAS in a few scenarios it might be used for in an office environment. The best performance with all the tested arrays came via the File Server test. The fastest speed of 215.33MB/s came from a RAID 5 array while the slowest, 193.38MB/s came from a RAID 6 array.
