5 replies on PCI Express 4 vs PCIe 3: Is there a performance improvement?

  1. Sequential Read / Write in SSD? says:

    OK, performance is better when doing sequential read/writes, great. But since it is generally recommended to not do disk defrag on SSD’s, exactly how do is a user supposed to optimize his drive to allow sequential anything on SSD?
    .
    Does the Win10 drive optimizer help any with this requirement/preference?

      First of all, thanks for reading. 🙂 The fact that performance is better in sequential read/writes means that the SSD is very fast at copying and moving large files, such as when you are copying ISO files or videos (each having sizes of several gigabytes). Optimizing a SSD doesn’t mean defragment it (that’s actually a bad thing for SSDs), it means trimming the SSD.

    I wanted a system that would be good enough to use for at least 5 years so when I build a new computer I try to use components that are less than 1 year old.

    Hi There, I just wanted to say thank you for running the benchmarks showing the difference in performance between the PCIe 3.0 vs 4.0. I have an X570 TUF mobo with a 4.0 slot and will be upgrading my GPU. This information was extremely insightful. I’m a competitive gamer so I focus primarily on high FPS at low graphic settings. Based off your stats, the 4.0 would appear to benefit more like a video-editor than a competitive gamer. There are GPUs out there that run on 3.0 interfaces that outperform the ones running on 4.0 slots. Really appreciate the info! Thank you for your work.
