PNY XLR8 CS3140 M.2 NVMe SSD Review: Is it the fastest NVMe?

I tried testing this SSD on my Intel i5 computer that has 8GB 3200MHz RAM on it. The results were pretty impressive. You can see them below. I used CrystalDiskMark and AS SSD Benchmark software to run these tests.

Average sequential read6,087 MB/s
Average sequential write5,516 MB/s
Average 4K Random Read82.3 MB/s
Average 4K Random Write235.6 MB/s
Average 4K Deep Queue Read1,458.2 MB/s
Average 4K Deep Queue Read 1,123.1 MB/s

You can clearly see that the PNY XLR8 CS3140 is offering impressive results. The tests results were not the same in this software but I tried to give you the average numbers which you can expect on an i5 computer.

The results will surely vary as per your overall system configurations, total space filled, and the storage variant as well.

Note: This SSDs requires a PCIe 4.0 supported motherboard and an M.2 PCIe 4.0×4 slot to offer their maximum performance. The PNY CS3140 surely has a backward compatibility with PCIe 3.0×4 but installing it on a PCIe 3.0 slot will bottleneck its highest speed.
