Lexar's new NVMe drive with 7 GB / s read speed (3 photos)

Developers of the American corporation Lexarcreated a prototype of a new solid-state drive that supports the NVMe protocol and is equipped with a PCIe 4.0 x4 interface. According to representatives of the company, the new device will be able to provide significantly higher data transfer speeds than modern SSD drives working with the PCIe 3.0 x4 interface.

It is assumed that the first solid statedrives of the new architecture, even without a brand name, will be released in the second quarter of 2020 and will provide a read speed of about 7 GB / s, and sequential write speed will reach 4 GB / s.

During testing of the prototype presented, the testCrystal Diskmark showed a read speed of 6.2 GB / s, and a write speed of 4.2 GB / s. At the same time, company-wide Iometer test results showed read speeds in excess of 7.5 GB / s.

More detailed specifications of the newSSD developers keep secret. However, experts believe that already published data may indicate that the device uses a Phison E18 controller. In the production of the new SSD drive, a 12-nm process is used, NVMe 1.4 is supported, 96-layer 3D TLC flash chips and LDPC ECC technology are used. The drive also uses the M.2 2280 version equipped with a radiator. The price of the device was not disclosed, and market entry is expected in the second quarter of 2020.
