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.

    Brian, can you please have a head to head comparison between the Exinos and Qualcomm variants of the S4? I am really curios whether the Octa really means something in terms of battery and performance...

    I think, Samsung's design is more repairable. So, for most of the people, its design is practical, easily repairable, makes the parts cheap and longer availability of parts compared to other phones... Yes they could have offered a better hardware design. But the amount of useful customization on the software side cannot be overlooked. I think software is the way to go because the hardware by itself is basically useless. Samsung's is the most customized OS in the android market. And, that hasn't affected the device's battery life or performance is a great achievement. So, as much as I hate the look of the phone... I will have to say the cost of the phone is worth it. Just for argument sake, how much do you think iPhone or SZ would cost with as many features as S4?

    If the build quality is good, then it wouldn't need to be repaired.

    Soon i will have it in my hands but once more the back cover is not the best and you can't use it withaout a case.. One drop and you have to search your pockets very deep! I'am looking for S4 cases and so far i have found only http://www.caseutopia.com to order some protection cases... better be safe than sorry. I hope someday samsung will produce smartphones with stronger materials. This is the only negative i find on this phone everything else is cool!

    Whaa Plastic... Whaa aluminum... Noooo HTC is best... Nut uh Samsung is better... Ya know what.. I have a Galaxy Note 2, am very happy with it. Get whatever phone suits you best, but before you buy, know this... Not a single phone out there tastes as good as, or, looks as good as pussy... Pussy, because any phone can order a pizza. That is all!

    If you compare them, please remember to mention that the Galaxy S4 only offers 9GB of storage for Apps(SD-Cards don't do anything to increase storage for most functions) where as the HTC One offers 25GB for available storage. Music and Pictures can be streamed/uploaded via the Cloud and those are the only two things that the SD-Card really will do for the Galaxy S4. With games getting bigger and bigger and Google Music streaming the minuscule amount of storage on the Galaxy S4 makes the phone feel pointless combined with the excellent underlying hardware. It's like having a Ferrari with a Lawnmower's gastank, where as the HTC One is a Lamborghini with an actual gastank.

    I'll admit I got the One for the looks and the camera. But I've found I really like Sense5 and Blinkfeed. Before I got it I thought I would never use it, now I use it constantly. There's a lot about touchwiz I don't like. All personal preference though.
