New Lexar NVMe SSD speeds over 7 GB / s

This is the fastest PCIe 4.0 SSD.
Not so long ago, consumer solid-state drives with PCIe 4.0 x4 interface and NVMe protocol support began to appear on the market. All of them were built using the Phison PS5016-E16 controller, therefore, they demonstrate similar speed indicators – about 5 GB / s.

The situation may change with the release of SSD, a prototype of which was demonstrated by Lexar. This device should be released in the second quarter of 2020, but for now it does not even have a name. However, the manufacturer claims that the drive can reach speeds of about 7 GB / s in sequential read mode and 4 GB / s in sequential write mode.

In the Crystal Diskmark test, the performance was approximately equal to 6.2 GB / s and 4.2 GB / s, and in the Iometer test the read speed did exceed 7.5 GB / s.

Lexar does not disclose details about the components used in the SSD, but it is likely that it is the unreleased 12-nanometer Phison E18 controller that supports the NVMe 1.4 protocol and 96-layer 3D TLC NAND flash memory. The M.2 2280 size drive is equipped with a radiator.
