Android devices, entry level Intel, and some Linux type boards comes with varying degrees of quality of internal eMMC Flash storage, that the Firmware, OS, Software & Apps runs from.

There is also cheaper microSDHC cards that can be used for device storage, but they are slower for day to day usage, especially when saving Random bits of Artwork, Thumbnail data etc, that Kodi does regularly - and long term regular, cheap microSDHC is not as reliable.

So it's a trade off, do you want cheap - or something faster, with better long term reliability.

The ODROID N2 has removable high quality, fast eMMC flash storage modules available that can be user configured to any OS you want easily.
The CoreELEC edition of the N2, uses a more robust, Industrial spec. Sandisk microSDHC - but it will still be a bit slower vs eMMC flash storage.

Thank you, so eMMC flash storage can be installed on the N2 simply as plug and play purchasable piece of hardware and swapping the Corelec OS from the default SD card to the new flash drive us doable from a layman's perspective ? Asking because an about to order an N2,

Yes you follow the instructions HERE (click) after SSH logging into CE running on the N2. (all further info is on the CE forums)

The 16GB eMMC modules are faster vs the smaller 8GB ones.

Just be aware if you want to flash any other OS to eMMC you will need one of these (click) You then use a microSDHC > SD card adapter as well.

Also I highly recommend a separately purchased MINIX A2 lite mini keyboard remote. It makes for a seamless OFF / ON functionality with CE on the N2 once setup.

MINIX are about to release an updated, backlit version of that A2 lite remote.
