Storage Architecture Evolution: PCIe Gen 5 SSDs and DirectStorage on Modern Operating Systems

High-speed storage with throughput above 12 GB per second is often held back by a bottleneck in the CPU's data decompression process before it is finally sent to graphics memory.

DirectStorage removes this obstacle by letting the graphics card read compressed assets directly from an NVMe SSD and decompress them in parallel using GPU cores. CPU load drops sharply while loading wait times shrink to milliseconds.

Beyond gaming, this breakthrough matters greatly to data scientists processing AI model training files hundreds of gigabytes in size without memory transfer latency.

The tight integration of fast storage and compute accelerators has become the new performance standard for modern computing systems.
