PM1743: Adata and Samsung show NVMe SSDs with PCIe-Gen5 and 14 Gbyte/s

Adata and Samsung have announced the first NVMe SSDs that support a PCIe Gen5 interface for particularly high data transfer rates. They reach a speed of up to 14 GByte/s sequentially.

Fast PCIe Gen5 SSDs from Adata and Samsung

We have already reported about the two Adata models Blackbird and Nighthawk . Both cards in the M.2-2280 form factor come to a speed of 14 Gbyte/s when writing and come to capacities of up to 8 terayte.

Samsung, on the other hand, is taking a different approach with its NVMe SSD with PCIe Gen5 connectivity, as the newly introduced PM1743 is designed for servers. The SSD is to be offered in 2.5-inch U.2 and E3.S Ruler formats. Depending on the model, between 1.92 TB and 15.36 TB of capacity will be realized.

Samsung does not reveal which controller and flash memory will be used. However, it can be assumed that the Koreans will use their own developments. Adata uses Innogrit IG5666 (Blackbird) or Silicon Motion SM2508 (Nighthawk) as controllers.

Almost twice the performance

According to Samsung, the PM1743 manages up to 13 GByte/s and 2,500K input/output operations per second (IOPS) in read mode. Writing, after all, is said to realize up to 6.6 GByte/s and 250K IOPS. Compared to the older PM1733 model, this corresponds to 1.7 to 1.9 times the performance, while efficiency is also 30 percent higher.

Volume production of the PM1743 is scheduled to begin in the first quarter of 2022, and partners are already receiving the new SSD for use. Intel’s Sapphire Rapids SP is among the first server platforms that can handle PCIe Gen5. The platform is also scheduled to launch in spring 2022. AMD follows suit with the Epyc 7004 shortly after.
