Install to internal to speed things up (Mecool M8S Pro+)

I'm running Libreelec from USB at the moment on a Mecool M8S Pro+ in dual boot.

It works, but sometimes it's a little sluggish. This is probably due to my USB stick, which is not the fastest but it was the only one lying around.

I've read that it's possible (though not recommended) to run Libreelec from the internal eMMC.

This should speed things up a little right?

What are the (real) disadvantages of ditching Android and run Libreelec from internal eMMC?

Is there a way to revert back to Android if I need to eventually?

As far as I know the M8S Pro+ has DRM – Widewine Level 1 and HDCP 1.x certificates. How can I backup them?

Is running from (fast) SD really an advantage?

I'm not trying to be a cheapskate but just checking what suits my needs best.

Any one that could help me out here?

Don't do it.

I know this is what most people recommend.

But what is the problem exactly of doing it?

Thanks guys, much appreciated.

If I would buy one of these Sandisk Ultra 16GB Micro SDHC UHS-I I'm golden?

You can try this:

[HOWTO] Boot from SD card, use internal memory for data

Setting it up this way will only use the SD card for booting and all data (that needs to be read fast) is on the internal eMMC, is that correct?

Thanks for the explanation.

With the symlinks you mean "[HOWTO] Boot from SD card, use internal memory for data"?

Or are there any other symlinks I need to know?

At the moment I'm convinced to not install to internal eMMC and use a microSD.

But I don't have any lying around so I'll have to buy one anyways.

What will be faster -> slow SD with data on eMMC or ultra-fast class 10 SD card?

Ok, cool. Thanks!

I'm in doubt:

Lexar 633x (LSDMI16GBBEU633A)

Sandisk Ultra 16GB Micro SDHC UHS-I (SDSQUAR-016G-GN6MA)

Ok, I read the whole thread.

I'll give a fast microSD a change.

Probably the Lexar one or are there any better ones in same price range?

Thanks for your answer as well!

Though I have to buy a new microSD card because I don't have one spare.

So if you are in my shoes and new to buy a new card anyways.

Would you buy a cheap (slow) card and put the data on eMMC or buy a faster microSD and run all from that?

Cheapest microSD (4GB) I can get is 6 euro.

The Lexar mentioned above can be mine for around 13 euro or the Sandisk for 10 euro.

One more question...

Why not use a (fast) USB stick instead of microSD?

Any disadvantages of doing that? Or only because they are more expensive?
