Samsung official explains why the microSD slot was gone in the Galaxy S6 and is back again in the S7
With the Galaxy S7 and S7 edge, Samsung reintroduced the microSD card slot for storage expansion. Both phones now come with a pretty generous 32 GB / 64 GB of internal memory and accept cards of up to 2 TB. It only makes sense that a flagship capable of 4K video recording would actually have the space to store the clips it takes, after all.
The new UFS 2.0 memory wouldn't gel well, performance-wise, with a microSD card slot, Samsung fearedSamsung head of technology, content, and launch management Kyle Brown spoke for TechRadar, saying that a microSD slot in the Galaxy S6 posed a risk to slow down the device. If you recall, it was the first handset where Sammy introduced its super-fast UFS 2.0 memory, which was almost three times faster than the previously used eMMC 5.0 chips. Samsung was concerned that data stored on the microSD card would be read slower, thus bogging down the phone's performance.
Since the new Galaxy S7 and Galaxy S7 edge handsets are just an upgrade to the fundamentals that were already laid down by their last year's predecessors, instead of an entirely new concept, Samsung was able to work on a solution and “get the best of both worlds”, Mr. Brown said. He continued to note that the return of the midroSD slot was one of the features of the S7 that received the most positive reaction from consumers, but also said that the team is very proud of bringing water- and dust-resistance back to the Samsung flagship line.
A true tech hurdle, or did Samsung just backtrack on a business decision that lost it some customers — what's your take?
