Today, Samsung announced that it has developed the PM1743 solid-state hard drive for enterprise servers. The PM1743 solid-state drive has the latest PCIe 5.0 interface and Samsung’s 6th generation V-NAND flash memory technology.
Samsung said that PCIe 5.0 can provide 32GT (Gigabit transfer) bandwidth per second, which is twice that of PCIe 4.0. PM1743 adopts a controller specially designed for the latest PCIe standard, which can provide good read and write speeds to meet the performance requirements of data centers.
Samsung PM1743 has a sequential read speed of 13000MB/s and a random read speed of 2500K input/output operations (IOPS) per second. Compared with the previous PCIe 4.0-based products, the speed is increased by 1.7 times. And 1.9 times.
In addition, the writing speed of Samsung PM1743 has also been significantly improved, with a continuous writing speed of 6600MB/s and a random writing speed of 250K IOPS, which are respectively increased by 1.7 times and 1.9 times. At the same time, this new solid-state drive has higher energy efficiency, up to 608MB/s per watt, which is about 30% higher than the previous generation.
Samsung PM1743 has a variety of capacities from 1.92TB to 15.36TB and can provide a traditional 2.5-inch form factor, as well as a 3-inch EDSFF (a solid-state drive form factor designed for a new generation of enterprise servers and data centers). Compared with the use of 15 mm 2.5 inches, users who use 7.5 mm EDSFF solid-state drives can double the system storage density.
According to reports, Samsung PM1743, as a PCIe 5.0 solid-state drive that supports dual ports, can ensure the stability and high availability of the server even if one port fails. At present, Samsung is providing samples of PM1743 to global chipset and server manufacturers for subsequent joint system development. Samsung hopes to start mass production of PM1743 in March 2022.
