To find out the actual performance differences between PCIe 5.0 and PCIe 4.0, I ran a series of tests. I started by testing the system with PCIe 5.0, which is the default setting. Then I went into UEFI to change the PCIe settings for the SSD so it would run on PCIe 4.0 and ran the tests again. Before running the tests, I made sure all my software and drivers were up to date. And to get accurate results, I ran each test multiple times and averaged the numbers. Here are the results I got and what they mean:
What do the tests show when using SSD on PCIe finland telegram data 5 compared to PCIe 4?
I started with CrystalDiskMark , a synthetic benchmark that can give you a pretty good idea of how SSDs handle different types of data transfers with both large and small files. The Corsair MP700 Pro SSD was generally faster with PCIe 5.0, especially when reading large files: It was about 50 to 66 percent faster. However, when reading small chunks of data from multiple sources at once, PCIe 5.0 was only slightly slower about 1 percent than PCIe 4.0. On the other hand, for single data requests, it was 9 percent faster with PCIe 5.0. In other words, PCIe 5.0 seems to be great at heavy read tasks that involve transferring large files, but the SSD can perform just as well on PCIe 4.0 for random reads.

The write speed results are also important because they show how well the SSD performs at tasks like saving files or running applications that create temporary files. And when it comes to writing data, the Corsair MP700 Pro SSD on PCIe 5.0 shows better performance than when it’s running on PCIe 4.0. The improvement is huge for sequential writes, with speed gains ranging from 69% to 71%. However, for random write tasks, the PCIe 5.0 SSD was only 2% to 6% faster. Similar to the read tests, these results show that PCIe 5.0 is great for writes that involve large files, but the improvement is limited to a couple of percent for random data.
