QNAP TS453be vs Asustor AS5202T I am new to NAS and looking at my first purchase. In short, I would like to be able watch media locally by HDMI using a service like Plex, have some further space for backing up material and have the ability to access the drive over the internet. I think my budget will extend to a 2-bay NAS and I expect my initial storage to be 4TB in RAID 1 or 6TB in RAID 1. After much research, I think i have narrowed my choice to between the QNAP TS-253Be and the Asustor AS5202T. I am having difficulty in deciding which to opt for. In support of the Asustor, it appears to be a little cheaper, it supports HDMI 2.0 (and so can play higher quality media and is somewhat future proofed over HDMI 1.4 in the QNAP), and it has DDR4 RAM. The QNAP appears to have a more powerful quad-core processor. Further, though I am less clear on this, I think the QNAP better supports its HDMI output.
Qnap in fact released TS-251D which is an alternative to AS5202T Nimbustor 2 NAS. It features the same Celeron® J4005 dual-core processor and 2GB more DDR4 RAM. It also comes with HDMI 2.0 connection. The 2.5Gbe ports will probably not be any useful if your existing network is 1GbE. Also, Qnap features PCIe slot which is a very handy thing if you want to upgrade your NAS to 10GbE or SSD caching.
So I would choose AS5202T if I wanted to connect to HDR TV and stream HDR movies. Its HDMI2.0a connections support this, whereas Qnap does not.
TS-251D would be a great choice and affordable solution for 4K streaming via HDMI2.0. Also, this would be an option if I planned to upgrade it later on.
TS-253Be would be almost 50% faster NAS which could be used for things like Virtualization, web server and more.
