Microsoft DirectStorage API reportedly makes Older PCIe SSDs as fast as New-Gen PCIe 5 SSDs

Forspoken is the first game to support Microsoft’s DirectStorage API, which significantly improves load times on various generations of SSDs. Compusemble, a tech channel, recently posted a benchmark video demonstrating the game’s difference in load times and frames per second using Microsoft’s DirectStorage 1.1 programming interface.

Microsoft’s new DirectStorage 1.1 API aids in increasing the load time of software, including games, by utilising compression and decompression asset algorithms managed not only by the graphics card used, but also by the solid-state drive controller, while reducing processor strain. As any instructions from the NVMe are reduced, this process results in a higher level of data transfer.

Compusemble tests three generations of PCIe SSDs using Microsoft DirectStorage 1.1 to see how each interface handled the new software.

ADATA XPG SX8200 Pro (PCIe 3.0), Samsung 990 Pro (PCIe 4.0), and Phison E26 drives were used (PCIe 5.0). What was discovered was quite unexpected.

The ADATA XPG SX8200 Pro produced a total load time of 13.838 seconds according to the test results. The Samsung 990 Pro took 10.872 seconds, while the Sony E26 took 10.483 seconds. The difference between the third and fifth generations of PCIe SSD was slightly more than three seconds. However, the raw data throughput difference between the two generations was four times greater on PCIe 5.0 compared to PCIe 3.0.
