A great entry-level NAS, with a powerful CPU for the price. The CPU is an ARM based quad core 1.4GHZ. It's got easily more than enough CPU and RAM performance for the Movie Streaming(Once converted to H264 Mp4 files they work flawlessly sending to the ChromeCast), and the m4a and mp3 streaming is second to none.
Works with Chrome and Opera browsers I've tested it with(Chrome and Chrome based Chromium on Linux), and Chrome and Opera on Windows 10. My video files I had to convert to the H264 files as I said, had to figure it out from a post on the QNAP website(that I needed Mp4s) and from choosing the most popular one on a Video Converter on windows(H264 Mp4 files).
File copy of my work copies across the LAN to the NAS at 65Mb/s. Very nice!. I'm not using a Gigabit Switch for the NAS, when I do copying from the NAS will be a better speed.
It was right within my bugdet of 270 odd dollars including shipping. And for what I could spend, it exceeds expectations. A more expensive one will be better in some ways, but I'm quite satisfied.
