Samsung has announced a new SSD with PCI-Express 5.0. However, they are not intended for private customers, but are intended to serve themselves in enterprise servers. According to the manufacturer, they will transfer data almost twice as fast as the previous generation and at the same time require up to 30% less power. This should significantly reduce the operating cost of the servers. The new SSD models run under the name PM1743 and integrate Samsung’s sixth-generation V-NAND.

According to its own statements, Samsung is already working in the background of products based on PCIe 6.0 to secure a position as a leading SSD provider for business customers. Intel worked on tests of the new PM1743. Together we were able to master the technical challenges in this early implementation phase of PCIe 5.0. The new NVMe SSDs are said to offer huge advantages especially in the areas of AI and Machine Learning as well as high-performance databases.

PCIE 5.0 allows a bandwidth of 32 gigatransfers per second (gt/s) – Samsung uses a proprietary controller to support the new standard. This means that sequential read speeds of 13,000 MB/s are possible with the PM1743. The random read speed is 2,500K input/output operations per second (IOPS). The write speed is 6,600 MB/s for sequential writes and 250K IOPS.

In addition, SSDs are much more efficient than previous models. There will be different capacities – from 1.92 TB to 15.35 TB. Samsung wants to offer the drive in both 2.5-inch and 3-inch EDSFF (E3.S) form factors. Furthermore, the new PM1743 is said to be the first PCIe 5.0 SSD with dual port support. To guarantee security, you implement your own security chip and Root of Trust (ROT). Secure boot is also supported in server systems.

Samsung is already supplying the first samples of the PM1743 to chipset and server manufacturers to develop the system simultaneously. Enterprise SSD sales will begin in the first quarter of 2022.
