When you say 'sequentialize' the data, are you talking about changes in how data is stored today versus in the past?

That’s exactly right. And the guys that are most aggressively doing this are the hyper-scalers. They control their file systems. They control the way data is delivered to the storage layer. For example, the fact that they’ve done this gives them two benefits. One is the differentiation between flash and disk on a performance basis. But it also allows them to take advantage of shingle magnetic recording, which is very well optimized to a sequential workload.

Those changes, and the fact that they are able to accelerate those changes, is one of the levers that continues to give them a big advantage over a traditional systems company that has more ‘heavy lifting’ to do in their file systems.
