Too expensive. I'll just set up a server at home and be done.
Not really.
Let's do some napkin math with some pretty generous cost assumptions in your favor. I'm also going to assume that Plex Cloud customers have no data caps, fast internet, and a need for a lot of storage.
I'm not up to date on server costs, but I'd imagine it is around $500 to buy the case, CPU for transcoding, the central guts (motherboard etc.) and all of those hard drives (I currently need 3TB for Plex, so that's 6TB in RAID 1). I don't think those little NAS boxes on Amazon can transcode, so I don't think they are an option here. Assuming the server is built powerful enough to run those big 4K files of the future, you can probably amortize it for 5 years. Let's just say $100 per year.
If you keep your server on for convenience, (like most people do since it
is a server), you are dropping an average of $10 a month for the power alone. So let's say about $90 a year since I'm sure that new CPUs are very efficient.
Then add in maintenance costs, which can be anywhere from $10 for a blown fan to the failure of a hard drive that costs $70. Let's assume that one component fails every 2 years, so let's say $25 a year in maintenance costs.
So on average you will pay $215 per year to have that server for five years. And I'll give you a 25% discount on top of that because this is napkin math and I'm drunk. So $160 per year, sound fair?
With Plex Cloud I'll save $60 every year, and I'll save a ton of time not dealing with all of the above. Even if you have
perfect luck when it comes to things breaking,
I don't think there is any question that this will cost more than the old fashion way of having your old server. The question is whether it will actually work.
I'm skeptical that Amazon will store many terabytes per customer when the average customer uses under 100GB. I'm skeptical that they won't mind if people uploading pirated media en masse. And while I have a gigabit fiber line, I'm really skeptical that very high bitrate 4K streams will be feasible from Amazon's end, cost-wise (many Plex users don't care about ridiculous bitrates, of course). But this is a beta to test scaling-up, so I don't think Plex minds the skepticism
Given that I like to stream my media at a very high bitrate, especially when it comes to 4K, I'm probably going to stay with my server

I'll still gladly try this out though! Honestly, I should probably just use a Bluray player instead.
Also I just edited a bunch of stuff due to aforementioned drunkenness
