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.

    I usually put phones in a case when I'm going out (and definitely if I'm carrying my smartphone on the job instead of my flip phone), but I like using them naked at home. So design still matters. Reply

    This phone really doesn't even need a case unless the owner is especially clumsy. Gorilla Glass 3 is pretty impressive. My Galaxy Nexus is unscathed after two years with it's "fortified glass" of unspecified brand. Naked phones FTW. Reply

    I don't use cases anyway, so that point to me is not valid. I have the HTC Sensation and ONE X and have dropped them both numerous times on the face and back. The ONE X's plastic case is more worse-for-wear even though its newer than my Sensation. Reply

    Gs4 is a cheap plastic phone. It is cheap because of the played out the design. When I shell out cash for a premium phone I want to feel that it is premium. When I hold a gs4 it feels like playing with cheaper variants that look the same. There is the galaxy note, galaxy s3, galaxy s3 mini, galaxy grand, galaxy mega, galaxy duos and a lot more. Don't get me wrong, i had a galaxy s3 and it was a beautiful phone when it came out. But Samsung abused it's popularity by making all phones look the same at the expense of the premium feel of the galaxy S line. Htc is by far the best designed phone you can get with the same price range. It packs the same punch as a galaxy s4 at the same price with better hardware.

    I believe that plastic is also chosen so it can be removable. Reply

    The Chinese version of the HTC One has a removable back plate with dual sim AND microsd expansion Reply

    I'm living in China now and I just found the removable back one quite disturbing, it boost the thickness to 10.2mm, and I have to give up theunibody aluminum, which is the only thing that one is superior to s4. In this case I would definitely go for a s4 with Exynos 5410 Reply

    I'd like to see that it must be an engineering nightmare to pull that off well. Reply

    Right, because all removable backs up until now (including all Nokia phones from the last 10 years) have been plastic.
    Oh wait!

    Not saying that. the ability of plastic to flex enables the little catches around the case to lock/unlock easily. to do that with alu you need a mechanical release which increases complexity. As a material plastic has advantages over glass/Alu and personally I don't mind it, not saying that I don't appreciate other materials just that as a functional cover it does its job well. Reply
