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.

    The smaller display on the HTC is a plus point.
    However even the HTC is too large for me.
    The perfect phone for me would probably be the Xiaomi Mi2S. The only thing it lacks is MicroSD, and popularity(support from XDA for alternative roms).

    You could get an S4. It is smaller than the One.
    It's never the display that is too large. It's the phone.

    You might have a point if everything you said wasn't wrong.

    Form follows function, if it does what it is supposed to and fits your need then that is what matters. If you just want the fanciest piece to show off to friends then you should speak to a professional about inadequacy issues or buy a gold plated iPhone. What are you going to do with it, use it, or just sit and stare at it as if it were a rare jewel. It's a phone/toy/tool not a Rolex to wear to dinner parties.

    I'd rather not have a phone that's built to be destroyed on FIRST impact...since I paid so much money.

    Because S4 buyers don't buy for looks or vanity? S4 is a looker to some people, there's no denying that. I'm sure we can all imagine an ugly 5" phone.... So don't erect straw man. HTC One is just better in the looks department to most.

    lol look at all the designer labels, appearance matters in real life I assure you.

    He didn't say he would.

    Is it that hard to realize that a lot people don't actually use cases for their phones?
  • darwinosx - Wednesday, April 24, 2013 - link

    I never use a case. Lots of people don't. Quit making excuses for Samsungs cheapness.
