Solid-state drives have entered the multi-gigabyte stratosphere. With PCIe 5.0 NVMe drives like the Crucial T700 reaching sequential speeds of 12,400 MB/s, gamers wonder whether upgrading from a top-tier PCIe 4.0 drive (like the Samsung 990 Pro at 7,450 MB/s) delivers noticeable real-world gaming performance.
DirectStorage and GPU Decompression
Traditionally, game assets were loaded from the drive, passed through system RAM, decompressed by the CPU, and then sent to GPU VRAM. Microsoft’s DirectStorage API bypasses the CPU entirely, streaming compressed texture assets straight from the NVMe SSD into GPU VRAM for instant hardware decompression.
Real-World Game Load Times:
- Forspoken (DirectStorage 1.2): Gen4 = 1.15 seconds | Gen5 = 0.88 seconds
- Ratchet & Clank: Rift Apart (Dimensional Portals): Gen4 = 0.92 seconds | Gen5 = 0.79 seconds
- Cyberpunk 2077 (Fast Travel to City Center): Gen4 = 5.4 seconds | Gen5 = 5.1 seconds
The Thermal Consideration
While Gen5 SSDs deliver jaw-dropping sequential read/write benchmarks, they generate substantially more heat—often requiring active fan heatsinks or massive passive radiators to prevent thermal throttling. For 95% of gamers, a high-quality Gen4 2TB SSD with DRAM cache represents the most balanced investment.
