While I am in the process of building a FreeNAS server to get some experience with it, I wasn’t planning on switching all three of our NAS over to the one system. I’ve been running two Qnap NAS for a while now and I love the flexibility they offer on the software side. So with the move to getting our data storage tucked away better in our rack, it was a perfect time to check out a rack-mounted NAS from Qnap. Specifically, their TS-453DU which has a matching non-rack mounted option in the TS-453D with that version also having 6 and 2 disk models and the rack-mounted version having 8 and 12 disk capacity options as well as a second 4 disk model with a redundant power supply. These are Celeron J4125 quad-core based and feature dual 2.5G network ports. This means we can do some testing to see how the 2.5G network that is coming with a lot of net motherboards can offer in real-world performance. So let’s dive in and see what the Qnpa TS-453DU has to offer for hardware, software, and performance!
