Samsung will be releasing its first PCIe 4.0 SSDs dubbed the 980 Pro, and on that PCIe Gen 4.0 link it achieves read speeds of up to 6.5 GB/s, there will be three models.
At this time specific specifications have not been detailed, so details of the controller and specifications of the NAND flash are unknown. However, the connection interface supports PCIe 4.0 x4, and the sequential access speed reaches up to 6,500 MB/s for reading and 5,000 MB/s for writing.
The 6th generation V-NAND, the latest 3D NAND from Samsung, will be used for NAND flash memory. The number of stacked layers has increased to 128, and not only capacity and access speed but also power efficiency have been improved compared to the previous generation V-NAND.The table below compares speed and power consumption with the previous model 970 EVO Plus. When using the 980 PRO with PCIe 4.0, the power consumption is the highest, but the performance per power is the highest.
Also, when using the 980 PRO with PCIe 3.0, power consumption is greatly reduced and it operates with lower power consumption than the 970 EVO Plus, so it has an advantage in the PCIe 3.0 environment. Three models will be released, 250GB, 500GB and 1TB. The release is scheduled for the second quarter of this year
