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.

    Thanks for the review - I look forward to Part 2. Also, it's good to know the highway is clear so you can run away from the killer bee swarms.

    A request to Brian Klug, and Anandtech!

    Any chance you'd start implementing comparisons of heat measurements for smartphones. Some of these latest flagships have so much horsepower in the them, the back cover heats up quite a bit under heavy use (not only games, but also navigation). It's almost like early light-n-thin laptops that became unusable cause of the heat on the palmrest or underbelly. Just hardware wise, such heat is detrimental to the phone itself in the long term. It could be a problem with last years flagships, so I'm guess this years ones could be more. A more strict analysis/measurement of how these smartphones manage and dissipate heat would be greatly appreciated!

    I'm amazed that people want anything OTHER than plastic in a phone. If you go with anything metallic you have to jump through major technical hoops to get good reception. Why even consider spending all that design money, not to mention making the many unseen compromises that this involves?

    For me this phone hits all the right points, including these two key items:

    • SD card so I can easily swap media sets in and out. Internal fixed memory can't begin to compete with with the speed, capacity, and convenience of micro/SD chips.

    • Replaceable battery , so that when it eventually dies I DON'T have to send the phone in for service.

    nothing wrong with plastic, as long as it isn't fisher price plastic.

    which it is

    Internal memory is much faster than microsd, fact. It is more convenient if everything is in the same place rather than having to swap things out, no? If you really need 32/64GB+ then sure microsd might be better for you, but with USB OTG this is not a big problem at all.

    Why did they have to use the cheapest plastic found in 25 cent toys from a gumball machine? I have a plastic phone, a Nokia 900, which kills this phone and any Samsung phone made in feel and durability.

    The GS4 is evolutionary, not revolutionary.
    Reminds me of a Cupertino company and their latest phone.
    Oh, how the Sammy trolls berated them for that.
    HTC One FTW

    And the HTC One is evolutionary (compared to HTC One X).
  • berantle - Wednesday, April 24, 2013 - link

    Compared to the HTC One X (and the rest), the HTC One is revolutionary in at least a 3 ways.

    1. The front-facing stereo speakers. If it was evolutionary, it would have been making a better quality rear-ward facing single speaker.

    2. The 4Mp UltraPixel camera. If it was evolutionary, it would have followed the herd towards 13MP camera and even smaller pixel-size sensors than the 8MP camera.

    3. The HTC Zoe (which I understand is short for "Zoetrope"). Automatically packaging short movies and photos taken into a simple 30 second presentation. You don't find that with other phones as best as I can see to-date. This is a big change from how it is done by cameras. Reading the reviews of the S4 here and elsewhere, what the S4 is doing seems like a belated response after seeing what the HTC One could do. A lot of people were caught flatfooted by what the HTC Zoe could do.

    These are 3 main revolutionary things that the HTC One has done. The S4? I can't see anything revolutionary. The Samsung Galaxy S4 is all about putting everything but the kitchen sink into it. If Samsung could shoehorn the kitchen sink into the S4, they would do it too - just to boast that it has a kitchen sink and no other phone has it.
