NVMe SSDs have transformed the responsiveness of modern PCs. But with the arrival of PCIe 5.0 models, the question arises: is it really worth paying more for a 5.0 SSD, or is a good PCIe 4.0 sufficient? We'll sort through the marketing figures and real-world usage.

Theoretical Speed: PCIe 4.0 vs PCIe 5.0

A good high-end NVMe PCIe 4.0 SSD can reach:

  • Up to 7,000 – 7,500 MB/s in sequential read.
  • Around 6,000 MB/s in write.

PCIe 5.0 SSDs aim for even more extreme figures:

  • 10,000 MB/s and more in read.
  • 8,000 MB/s and more in write.

The difference is impressive on paper. In gaming, the noticeable gain remains small compared to a good PCIe 4.0 SSD. For FPS gains, it's better to optimize RAM and GPU first.

Real-world usage: gaming, office work, creation

For a gamer, the difference is mainly seen in game loading times and heavy patch installations. But between a good PCIe 4.0 and a PCIe 5.0, even in gaming, the feel remains very similar. Where PCIe 5.0 makes sense:

  • 4K/8K video editing.
  • Massive transfers of large files.
  • Very intensive professional workflows.

Motherboard compatibility and cooling

Before you jump on a PCIe 5.0 SSD, check two critical points:

  • That your motherboard supports PCIe 5.0 on an M.2 port (see our motherboard guide).
  • That you have an suitable M.2 heatsink: 5.0 SSDs heat up significantly more.

Our verdict: PCIe 4.0 or 5.0?

For a gamer or a typical user, a quality PCIe 4.0 SSD is largely sufficient and offers the best performance/price ratio. PCIe 5.0 is a luxury useful only in very specific professional scenarios.
