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.

    Anyone who complains the iPhone is too light need to reevaluate their priorities. Reply

    Plastic does NOT get either dirty or scratched easier than metal, this is from an owner of 2+ year old galaxy S+, who never used any sorts of protective cover. The only marks on it are from dropping it on concrete from about 1.6 meters.

    This "it must be metal" madness should stop. Go apply that to other gadgets.

    If it doesn't come off looking like a 5 dollar chinatown toy, then yes. Don't get me wrong, there's nothing wrong with plastic, HTC and Nokia does it well, but the fisher price mode that samsung is in, i can't help but to feel Samsung could of done it a lot better. Reply

    Your argument is invalid. Smaller display is not a con for many people. You can't judge battery life by the capacity alone. Larger because of the speakers, I prefer larger any day to cuping the phone with my hands like an idiot and trying to hear something. Resistance to breaking or scratching still unknown. Heavier? yes, aluminum is heavier than plastic. Reply

    Smaller display IS a con. It's just that it often comes with a benefit: smaller overall phone.
    Samsung did the impossible and made a phone which is both smaller and has a larger display than the competition.
    If the Galaxy S4 was of the same size but with a 4" display it would suck.

    Resistance to breaking might be unkown, but it is known that light plastic devices survive better to drops than heavy alluminium ones. Plastic is light, absorbs shock and let waves pass through. Perfect material for a phone. If you want an heavier phone noone stops you from attaching a lead plate to its back.

    "but it is known that light plastic devices survive better to drops than heavy aluminium ones"

    Oh, "it is known"?

    That kind of attribution is not acceptable.

    Are you really denying that plastic is more shock-absorbant than metal? Reply

    Smaller display in not a con in this situation. The HTC has a better ppi and it has a LCD3 display which is actually better than the AMOLED screen on the Galaxy S4. The colours on it are just better and the blacks are not that bad. 0.3" is not much difference, if you want 25 reasons why HTC One is better check this video out from PhoneBuff on YouTube: Reply

    From the review;
    "If you compare the all-plastic Galaxy S 4 to the all-metal HTC One, there's a difference of 13 grams."
    I've seen several articles saying that Samsung is going to be upping their build quality because of the HTC One and iPhone and the constant perception by so many people that Samsung phones and tablets feel and look cheap.
