NAND Performance

The Galaxy S 4 ships with either 16GB or 32GB of NAND on-board, but allows for expansion via a microSD card slot. The latter is a quickly disappearing feature on modern smartphones, but it remains a point of differentiation offered by Samsung. We were sampled a 16GB version of the Galaxy S 4, which arrived with 9.62GB of usable space after the OS and app pre-load.

As always we're using Androbench (with modified settings) to quantify NAND performance. Thankfully NAND performance has been steadily improving on modern smartphones/tablets, and the Galaxy S 4 is no exception. Sequential read performance actually sees a tremendous boost compared to most of the other devices in our charts here. Optimizing for sequential read performance makes a lot of sense, but it's good to see Samsung being competitive on all fronts here.

It is worth pointing out that NAND is treated very much as a commodity in these devices, and it's entirely possible that you'll see performance deviate from what we've shown here depending on what controller/NAND/firmware combination you get in your device.

    What, no 3G, 4G and wifi comparative data bandwidth tests? Communications power is a big part of the things "raison d'etre" ! Reply

    Hi,

    I have problem with wifi connection at some hotspots and hotel rooms.
    I was told IPhone and IPad wifi power are not strong comparatively with Samsung or other android phones.

    Is it true ? Are there any official test or comparisons done.
    If there is, please provide website links.
    Thanks
