Because it is important: DirectStorage is one of several attractive features intended for Windows 11. Until this point, we had been led to believe that the technology, which was originally created for Xbox Series X / S, would be a Windows 11 exclusive. It turns out that is not the case in absolute. It may not be as fast as Windows 11 deployment, but at least Microsoft is serving its existing user base and developer partners.
Microsoft Program Manager Hassan Uraizee saying the company is committed to ensuring that when developers adopt a new API, they can reach as many players as possible with it. As such, games created to use the DirectStorage SDK will also be compatible with Windows 10, version 1901 and later, as well as the DirectX 12 Agility SDK.
Microsoft’s direct storage technology is about maximizing local storage performance by providing an improved link between storage and the GPU. Specifically, it provides a batch-style send / completion call pattern, “relieving applications of the need to individually handle thousands of I / O requests / completion notifications per second.” A later preview will also allow for GPU decompression to improve load times.
One notable difference between the deployment in Windows 10 and Windows 11 has to do with the storage stack. With Windows 11, DirectStorage will have access to an updated operating system storage stack to unlock the full potential of the technology, but in Windows 10, you will have to make use of the legacy operating system storage stack.
