I have no idea. Everything else they make is SSD. Just put a 128GB in there and let the spinner die.
Especially considering that:
A - They are hella cheap
B - Everything is on some sort of a cloud so local storage is irrelevant
I have an interesting issue so to speak that requires a bit of a back story.
I have a Roku TV, and as it is obviously a streaming client it has network connectivity both wired and wireless, it also has what is called private listening mode which is ability to use either a networked remote or the remote app on your phone to stream audio to connected headphones as opposed to outputing it to speakers/soundbar. The feature is rather handy when everyone in the fam goes to bed at least 2 hours before you do.
I also recently got an XBone, which of course also has network ability also both wired and wireless and since everything is in the cloud these days that is how I get my games as opposed to physical disks.
Since 4k streams are rather large when I originally set up the TV I used a wired connection (I also had a slower wi-fi network at the time). So figuring that since my network is now 802.11ac and Xbone is pretty new and not wanting to run a wire to it I set it up for wi-fi. However the game downloads were rather slow (and they are big ass downloads) so I decided to switch it to wired and put TV on wi-fi. That didn't actually speed up game downloads that much as it appears their server is the actual bottleneck because even the Xbone built in speed test shows speed capability of at least 5x of what it runs at.
At first it didn't seem like the TV was much affected by being on wi-fi, that is aside from private listening going all wonky, it would get out of sync, randomly go silent, sometimes fail outright with a message. Last night was the worst so I switched the TV back to wired and the issues disappeared... I'm thinking that those big 4k streams are using up all the bandwidth so there isn't enough left for the audio stream. Not a huge deal obviously but is a little weird.
