Should I Choose a PCIe 3 or PCIe 4 SSD for Windows 11?
Asked by
TechNinja2023
I'm currently using a 1TB PCIe 3 NVMe SSD for my system and planning to upgrade. I'm considering adding a 4TB SSD for games and a new 1TB SSD specifically for Windows 11. If I stick with my older PCIe 3 SSD for Windows, will I notice any significant difference compared to using a PCIe 4 SSD? I have the budget for the upgrade, but I'm curious if the performance difference is worth it or if I can save that money for something else.

You'll really only see differences in benchmarks, not so much in actual gaming performance. Even in high-demand scenarios, the random I/O speeds have a bigger impact on your OS than the peak sequential speeds of the SSDs.

If you’re asking whether you’d notice a difference day-to-day, probably not much. Unless you’re looking at benchmarks or doing very specific tasks, both types of SSDs can deliver a smooth experience in general usage.

What really matters is the SSD's DRAM cache. A PCIe 3 SSD with a good DRAM cache can outperform a more expensive, DRAM-less PCIe 4 SSD in file transfer speeds. So keep that in mind when choosing your SSD!

PCIe 3.0 SSDs generally hit around 2.5-3GB/s, while PCIe 4.0 can reach about 7-8GB/s. You probably won't feel this difference during regular use, but if you're frequently loading large files, the speed boost from PCIe 4 can definitely come in handy.

In everyday tasks like gaming or web browsing, the performance difference between PCIe 3.0 and PCIe 4.0 SSDs isn't that noticeable. For most users, PCIe 3 is still very capable. However, if you handle large files or do tasks requiring fast storage, then a PCIe 4 SSD could be noticeable during those specific activities.
