Do you know how fast Samsung Galaxy S4 internal NAND storage speed is? Well, it is almost 4 times faster than Galaxy S4 in term of reading speed. And twice for writing speed. Who care about this? For those wish to swap internal storage with external SD card or move games data to external SD card users. As usual, internal NAND storage is always faster than external SD card. But the question is how much…


Galaxy S4 storage performance with A1 SD Bench

A1 SD Bench is the tool that I used to benchmark. As you can see, Samsung Galaxy S4 internal NAND memory is much faster than external SD card. For your information, Galaxy S4 does not support UHS-I standard. Therefore, my 64GB Samsung microSDXC Pro UHS-1 Card can’t get 70 MB/s reading and 20 MB/s writing on Galaxy S4.

As a result, Galaxy S4 internal NAND memory is 6 times faster than external SD card on reading. And 3 times on writing. Therefore, do take note of the slowness that you will face when swap internal storage with external SD card or move games data to external SD card.
