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.

    Why did you use the 3rd gen ipad instead of the current model? Just because than Apple would have been at the top of every GPU chart?

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

    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

    My current model is IPhone 5 and IPad Mini.

    Are there any official test or comparisons done.
    If there is, please provide website links or email to me: davidsegar77@yahoo.com.
    Thanks

    I know this is years late, but my S4 is utilizing an IMX135, not an IMX091.
