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.

    Pretty sure he only has that on loan for brief periods of time. He doesn't own it, too expensive.

    Brian, will you be getting the Exynos 5 octo-core version of the S4 in for testing? I find the SoC interesting.

    Wow biased much? Why did anantech let this guy review this? He's already shown he's biased towards the HTC One.

    he said if X,Y,Z are important to you then get the S4, but if put more weight on A,B,C then HTC one is the better bet. How is that bias? go away.

    Samsung is bringing out the trolls... brrrrrrrrr

    They never stop. It's like they get paid for their comments bashing HTC.
    Oh wait, they do according to DailyTech

    The Samsung astroturf trolling is highly disappointing.

    What a sour taste

    Is 50M S3 users are victims of Samsung brand and marketing?

    The screen mode "The sanest of them all" (we understand they are sick) actually beats both Iphone and especially One on accuracy. And no words about the all important dynamics of the picture.

    And the BSI camera on the S3 is the same quality as the S2? LOL. Every one on this planet shooting with both will know this is nonsense - comparing the international versions. Go to dxomark to get the numbers.

    Why does this admiration of the One leads to this sour subjective nonsense about Samsung and S4?

    Didnt the ultrapixels pan out as expected?

    I like it more professional

    What are you talking about? Look at the table. The iPhone 5, One X, SGS3, Droid DNA, and the One all beat the SGS4 on accuracy, i.e. a lower dE2000.

    And the color charts. Not that the perfect RGB spectrum is the most important.

    And then the all important numbers - or impressions - for dynamics of the picture is missing. Excactly the one most important factor deciding how real we judge the picture.
