Samsung Galaxy Note 5 will not get microSD slot
Samsung Galaxy Note 4 has one key feature for quite a few users, namely the microSD slot that Galaxy S6 devices pushed aside. Unfortunately, it looks like the high-end next-gen phablet by Samsung will drop this feature as well and its users will no longer by able to extend the amount of available storage with the help of a microSD memory card.
Despite the speculations that claimed Samsung launched the Galaxy S6 and Galaxy S6 Edge without a microSD slot because they had to remove it to achieve the desired thickness, the truth is different. While all competitors of the S6 family feature eMMC 5.0 internal storage, Samsung's flagships use UFS 2.0, the fastest internal storage technology available right now on the market. Unfortunately, while UFS 2.0 can perform writes and reads about two times as fast as eMMC 5.0, it is also too fast for any microSD card to keep up and requires a separate controller.
Since eMMC 5.0-powered devices can easily use a single memory controller for both the internal storage and microSD cards, things are not the same with those that use UFS 2.0. Given the major data write/read speed advantage of the S6 family over its predecessors, there is little doubt that Samsung will use UFS 2.0 storage for the upcoming Galaxy Note 5 phablet.
They may still find a way around the issues mentioned above and keep the microSD slot around, but that remains to be seen. For now, nothing is official yet.
