| Now, the truth is that when it comes to flash memory, the concept of random and sequential reads/writes doesn't really apply, because it comes from the world of hard disk drives. But just so you get the general gist of it - in random read and write operations, blocks of data aren't written in neat, organized clusters, but randomly spread all over the disk space. This is usually the case with most user applications, and in hard disk drives, it results in a reduced data throughput. That's because it involves lots of spinning of physical plates and a hard drive head rushing to get to the correct chunks of data in time, introducing latency - the original performance killer.

Sequential read and write speeds are important in regards to accessing and storing large files (such as high-resolution multimedia content). Single large files tend to be stored in uniform clusters of data on a singular region of disk space, in easy to follow sequences. Thus, even though flash memory doesn't really care how data is arranged, good sequential read and write speeds means nice performance in file operations. And with those hi-res video files and losless music taking up sizeable chunks of our mobile devices' disk space, it goes without saying that sequential read and write speeds matter. With all that into account, let's see how Samsung's flagship smartphones compare with the best of last year's technology in terms of memory performance. Looking at the impressive results posted by the former, it seems Samsung wasn't joking at all when it rallied about the Galaxy S6 & S6 edge's memory speeds. You've never seen anything like this in a smartphone! Unfortunately, it will be a while before UFS 2.0 memory reaches to mid and low-end tier devices, because right now, it's rather expensive to produce and is, thus, going to be a feature of flagship products.
