One of the big bets of AMD with the Ryzen 3000 is the implementation of the PCIe 4.0 interface. This one for graphics cards contributes little, but it does contribute a lot for M.2 SSD units. Through this PCIe 4.0 interface, high transfer speeds are being achieved. As is the case of the unit presented by Lexar that reaches 7GB / s.
The PCIe 4.0 interface for data transfer can offer almost 8GB / s for four channels. It makes obsolete not only mechanical hard drives, it also wrecks SATA SSDs. These high speeds are especially interesting for those who work with large files, such as photo and / or video editing.

We must understand that one thing is the theoretical data and another thing is the results in real environments. No unit on the market can reach the prescribed speed, normally they usually stay at 10% of the marked speeds. There are thermal problems, the communication process and the computation process, which reduce technical speeds.
This Lexar drive in the IOMeter stays pretty close to the configuration specified by the manufacturer. What this software measures is in heavy files, so it shows that it is a great unit for photo and / or video editing. On the other hand, in CrystalDiskMark it reaches 6.2GB / s of reading and 4.2GB / s of writing. These are really interesting facts.
Lexar has used 3-layer 96D TLC NAND type memories that have been manufactured by Toshiba. It has a heatsink, which is said to be quite ugly and does not seem one of the most efficient seen for M.2 drives. On when this unit will reach the market or what its sale price will be, no data has been given.
