Samsung Develops High-Performance PCIe 5.0 SSD for Enterprise Servers

Samsung today announced that it has developed the PM1743 SSD for enterprise servers, integrating the PCIe (Peripheral Component Interconnect Express) 5.0 interface with Samsung’s advanced sixth-generation V-NAND. PCIe 5.0 offers a bandwidth of 32 gigatransfers per second (GT/s), doubling that of PCIe 4.0. Samsung’s PM1743 will feature a sequential read speed of up to 13,000 megabytes per second (MB/s) and a random read speed of 2,500K input/output operations per second (IOPS), offering 1.9x and 1.7x faster speeds over the previous PCIe 4.0-based products.

Write speeds have been elevated significantly, with a sequential write speed of 6,600 MB/s and a random write speed of 250K IOPS, also delivering 1.7x and 1.9x faster speeds, respectively. These remarkable data transfer rates will allow enterprise server manufacturers deploying the PM1743 to enjoy a much higher level of performance. The new Samsung SSD can provide improved power efficiency of up to 608 MB/s per watt, which represents about a 30% boost over the previous generation. This is expected to lower server and data center operating costs significantly, while also helping to reduce their carbon footprint.

Available in a wide variety of capacities from 1.92 terabytes (TB) to 15.36TB, the PM1743 will be offered in the conventional 2.5-inch form factor, as well as in a 3-inch EDSFF (E3.S) — an increasingly popular SSD form factor designed specifically for next-generation enterprise servers and data centers.

The Samsung PM1743 is expected to be the industry’s first PCIe 5.0 SSD with dual-port support, guaranteeing server operational stability and high availability when a connection to one port fails. Samsung plans to begin mass producing the PM1743 in the first quarter of 2022. The Samsung PM1743 has been designated a CES 2022 Innovation Awards Honoree in the category of Computer Hardware & Components.
