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

The company claims huge numbers as the features of this SSD. Because CS3140 is PNY’s Flagship SSD, it is expected from it to perform properly. Let’s see what are key specifications you are getting with it.

Unfortunately, the company hasn’t disclosed its random read/write speed and the actual TBW limits. This can look a little bit shady but we will check the random speeds further in the benchmark tests. If we talk about the TBW, a 5 Years Warranty is enough to justify its reliability.
