After being unable to get my Subsonic DLNA server to show up reliably in my Xbox One S’ Media Player, I decided to use external storage for video playback instead. I was about to drop $50 on a 128 GB USB stick when I remembered I had a 64 GB Kingston Class 10 UHS-1 microSD card laying around. Buying a USB media card reader seemed like a more efficient solution, so I started looking into doing so.
Apparently – nearly 3 years after Xbox One’s release – no one’s bothered to try this. Or at least they never bothered to write about it, because my Google searches and forum posts turned up nothing definitive.
I wound up having to get a couple readers and try them out myself, and both of them worked. This leads me to conclude that the Xbox One does in fact support media cards via USB readers. That said, you definitely want to get the fasest reader, and the crown for that goes to the Kingston MobileLite G4. This is the only reader I found with USB 3.0 and UHS-II support, which should future-proof you for ultra high bitrate (e.g. 4K) playback given a correspondingly fast microSD card. The G4’s only downfall is it supports SD and microSD only, but when’s the last time you saw any other media card in use in the wild?
You can pick the G4 up for as little as $8.95 online, which is much less than the $50 I mentioned earlier.
A local option is the Insignia NS-CR2021 USB 2.0 SD/MMC Memory Card Reader which, as its name suggests, also supports MMC and MMC+ cards. Unfortunately it’s limited to USB 2.0 only and there’s no mention of UHS support anywhere.
