QNAP TVS-872XT-i5-16G 8-bay NAS Review

We tested the TVS-872XT 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

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

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

Digital Video Surveillance
160GB file size, 128K Block size, 90% Read 10% Write, 100% Sequential, Boundary: 512K, I/O depth 64 Threads/Workers: 8

While the File and Web server tests produced much faster average speeds when using either a Thunderbolt 3 or 10GbE connection than the 1GbE connection, the Database test produced results that were a lot closer between the three connection speeds.

The fastest performance in the second group of workload scenarios came in the Media Streaming Test using a Thunderbolt 3 connection and a RAID 6 array which gave an average speed of 877.15MBs.
