I tried QNAP, WD and Buffalo but Synology is still the best in my opinion. When buying, get the one with more bays than you need as you’ll probably find yourself needing an upgrade sooner than you think. If your budget allows, get a + model, they are worth the extra and you can up the RAM.
220+ is really good but find it noisy compared to my other Synology. I added another 8 GB of Ram to mine.
The 30GB+ (Regularly) is 1080p. For 4K we’re looking at 80GB+ depending on how I rip them and whether I use Handbrake to adjust the size There’s no transcoding with Infuse. This is far better then Plex. So, I’d highly recommend trying it. 🤙🏻
A total file size is really not a helpful unit of measure. A 30GB for a 4k movie is quite small. My Dunkirk 4k rip (under 2 hour film, bitrate 58219 kbps is 45gb. The Matrix 4k (2hr 15min) bitrate 48842kbps is over 50gb. Streaming from your NAS via plex will mostly rely on whether Plex has to do an on-the-fly transcode to play it on your device, or not. That is really what matters.
This unit can stream a 4K file easily over your network. I regularly stream 30GB+ files (Ethernet) to my iPhone, iPad, Apple TV.If anyone has a big library, or big files. I'd highly recommend Infuse by Firecore to stream if you're on iOS devices. A much better experience than PLEX in my eyes. https://firecore.com/infuse
