Hey everyone,

I just got the UGOOS AM9 Pro and I’m looking for the best microSD card to boot CoreELEC from.

Any recommendations for something reliable and fast? Mainly looking for good stability and boot performance.

Would really appreciate your suggestions 😊
Thanks!

Looking for real-world input from CoreELEC-only users. Not interested in Android TV opinions — purely CE playback use case.

My situation:

•	Primary use: CoreELEC only (booting from USB/SD)

•	Content: 4K Blu-ray remuxes and full disc ISOs, frequently 80–120GB+

•	Must-haves: DV Profile 7 FEL passthrough, VS10 tone mapping, stable high-bitrate playback

•	Future-proofing: want the box to handle whatever codecs come next (AV1 especially)

What I’ve found so far:

The Homatics Box R 4K Plus (S905X4-K) seems to be the community favourite for the “does everything” crowd.

But the FEL situation concerns me. CE-NG is EOL. If FEL on the Homatics only works reliably on a dead branch, that’s not a stable long-term setup — that’s a ticking clock.

The Ugoos AM6B+ keeps coming up as the gold standard for FEL specifically, but it lacks AV1 hardware decode and stock availability is getting tight.

My actual questions:

- Can homatics play high bitrate movies with dv fel 7 smooth ?

- Is dobly 10 tone mapping working fine homatics ?

-is homatics future proff for codecs like av1 and vp9?

-or i can look at other devices if you have a suggestion pls?

Thanks for you answer
