Ditching the ultra-convenient microSD card slot on the Galaxy S6 was probably one of Samsung’s most ill-advised business decisions in years, but aside from the profit-boosting aspect of it all, there was also a noble goal behind it.
Specifically, we were told this new Universal Flash Storage technology would be slowed down by external expansion, so if we wanted the highest possible data writing and reading speeds, we had to settle for local 32 or 64GB containers.
Now, it’s unclear exactly what might have changed in the past year, but the S7 and S7 Edge again feature microSD slots. Meanwhile, Samsung continues to innovate as far as internal storage is concerned, taking the wraps off the industry’s first 256-gigabyte embedded memory based on the UFS 2.0 standard.
Wait, does that mean a 256GB Galaxy S7 configuration is on the way? It’s not out of the question, yet most Western markets seem to be merely offered 32GB variants. No 64, and obviously no 128, as the latter model doesn’t exist, as far as we know.
It could perhaps mean the Galaxy Note 6 will skip microSD capabilities, but that’s unlikely to please a lot of S Pen-supporting phablet enthusiasts. Ultimately, this is probably another future-proofing move, as was the case for the 6GB RAM breakthrough, with actual commercial plans left to be worked out down the line.
It’s worth pointing out that, in addition to accommodating more data than before, the new flash memory chips are also smaller than external microSD cards, “giving greater flexibility to smartphone designers”, and provide transfer speeds exceeding those of SATA-based SSD solutions for PCs.
Yup, you’re looking at a mind-blowing 850MB/s sequential reading velocity and 260MB/s sequential writing acceleration, which combined with USB 3.0 standards, will allow the transfer of a 5GB-equivalent Full HD video clip in 12 measly seconds. Wow! Just… wow!
