The Advantages of Data Compression in Gaming SSD
This is not a novelty, sinceUsers of PS5 and both Xbox Series already enjoy the advantage. At the transfer speeds of an NVMe SSD, if we need to decompress the data as it is being transferred, we may find that not one, but several processor cores, have to be exclusively responsible for said task, thereby cutting performance. The trick? Add data compression and decompression units inside the graphics card.
Well, in the image above you can see the comparison when transmitting information from the SSD to the memory of the graphics card using DirectStorage and the integrated decoder in those that are compatible with DirectX 12 Ultimate. For stream 5.65GB of information, the process reduced from 2.36 seconds to 0.80 seconds and a CPU usage from 100% to 15%. So the process of decrypting the compressed data does not take any extra seconds. The main advantage of this? To have game installations taking up less space on the SSDbut above all to end the bottleneck of the lack of video memory.
It’s not just for games
Moreover, thanks to the DMA mechanism that every graphics card has to connect to the main RAM, we can use the GPU to decompress data from other applications. so all in the future they could be installed in compressed format. Which will mean that not only take up less space on the SSDbut because of its smaller size your transfer will be easier.
In any case, the applications where this is going to have the most impact are video editing and graphic design applications with large files. Since it will only be necessary to have in RAM the part of the file that we are editing and not all of it at the same time. Which is a huge performance advantage and will prevent speed drops in those cases.
In any case, we must remember that DirectStorage is exclusively available for Windows 11 and there are still no applications that take advantage of it, but once they do, we will see a substantial difference in the way many applications perform. So data compression on the SSD is going to completely change the paradigm for many applications that we use on a daily basis and will definitively retire the use of the hard drive. However, such applications will need to adapt to use this new capability.
