The Samsung Galaxy S6's Memory Is So, So Much Faster Than Other Phones

MWC 2015 had some pretty impressive announcements, but nothing as high-profile as the Galaxy S6. Here's the thing, though -- the next Samsung flagship smartphone has a huge improvement in one crucial, but under-appreciated area.

The Samsung Galaxy S6 and its S6 Edge counterpart will be the first released in Australia to feature UFS 2.0, a brand new flash memory standard that is at least three times faster than the eMMC 5.0 and 5.1 used in current and last-generation phones like the LG G3, HTC One M8, Samsung's own Galaxy S5 and even the relatively new Galaxy Note 4.

The difference isn't just incremental, it's enormous. When you're talking theoretical numbers of 250MBps for eMMC 5.1 and a massive 725MBps for UFS 2.0, that's a threefold increase in potential performance just from one aspect of the smartphone -- not even taking into account similar improvements with the S6's octa-core Exynos 2.1GHz + 1.5GHz processor and LPDDR4 RAM. This is quantum leap stuff.

Crucially, UFS supports simultaneous reads and writes -- so your phone can actually multi-task like its multicore processor suggests it'll be able to. Despite that, it prioritises incoming transfers, so if you're moving a bunch of movies or music onto your phone it'll happen as fast as possible. The actual difference? Testing in AndroBench the Galaxy S6's result of 77.2 is miles ahead of the Note 4's 20.6, the LG G3's 15.71 and the Sony Xperia Z3's 14.78. The difference between that first number and the last three is enormous.

That kind of yearly improvement is genuinely surprising. Samsung was one of the first to pioneer HEVC in smartphones, so it's great to see the company constantly improvement.

Need a bit more background info? Coming to us via the guys at PhoneArena again, here's a video explaining the differences between UFS and older mobile memory tech:



    And all this great meaningless stuff is in expense of battery life, hurray!!!

      Yeah its battery is tiny compared to the Z3. Let's see it last 14 hours :P

        Don't know why you're both going on about battery life. The S6 uses octacore cpu based on the little.BIG technology, of which slower 4 cores will probably be used for less intensive tasks to save battery, plus with faster memory it means data transfer will be quicker which again will result in less battery use, not more.

      Flash memory uses incredibly little power no matter what variant it is. This is pretty much just free read/write speeds.
      Phone Battery usage is basically Screen > Processor >>>>> Everything else (like 5% total)

      @ilusha and@kie723 OK education time. Although the S6 ships with a 2600 mAh battery, it has the fastest and most efficient processor on the market 35% more efficient than previous models. So if you combine a super efficient processor with other aspects of the phone, Samsung ensured it would not burn a ton of battery so having a smaller battery means nothing. Until test results come out it will most like last as long if not longer than previous models. You have to take into account all specs of a phone not just the battery size. Samsung assured everyone at MWC they would not have have a non-replaceable battery unless it was one of the best.

      Even though it's supposedly more energy efficient than emmc?

    Testing in AndroBench the Galaxy S6′s result of 77.2 is miles ahead of the Note 4′s 20.6, the LG G3′s 15.71 and the Sony Xperia Z3′s 14.78. The difference between that first number and the last three is enormous.
    A comparison to the iPhone 6 and 6 Plus would have also been nice. That's Samsung's real competitor.

      Anandtech included storage performance benchmarks in their review of the iPhone 6 (and Plus):

      Sequential read: 249 MB/s for the iPhone 6, 253 for the Plus, and 315 for the Galaxy S6. Sequential write: 86 for the iPhone 6, 82 for the Plus, and 139 for the Galaxy S6.

      Even larger differences in random read: 15.9 MB/s for the iPhone 6, 16.5 for the Plus, and 77.2 for the Galaxy S6. Random write: 1.4 for the iPhone 6 (a major regression from the iPhone 5), 1.3 for the Plus, and a whopping 19.8 for the Galaxy S6.

        ^How nice was that? A question was asked, a bit of research was conducted and a helpful reply was given without trolling, flaming etc. Colour me impressed.

      It's androbench, not iosbench

        So what? A lot of Android dedicated websites have comparisons to non Android phones. Get with the times.

    Battery life is around 22 hours. Also it has 10 min fast charge which gives u 30% battery. Considering iPhone 6 has half the battery life of the note 4. The s6 will stay alive far longer than any other phone. Samsung screen tech is the best by a mile. IPhone 6 injust 24 hours has been made to look outdated .

    The battery is a real shame!!! And in this price not even a fucking fm radio. My note4 is fast and lagless and all i waiting is to the siny xperia z4

      I heard it can't even send faxes either!

    This is awesome with wifi-direct... pretty sh*tty with the s6 usb 2.0...
