Samsung has published some preliminary details about its enterprise-grade SSDs featuring a PCIe 5.0 x4 interface. The drives will be available in an E3.S 1T form-factor within a year, just in time for the first PCIe 5.0-supporting enterprise platforms, like AMD’s EPYC Genoa and Intel’s Sapphire Rapids, to hit the market.
Samsung’s PM1743 solid-state drive will be based on the company’s proprietary controller as well as 6th Generation TLC V-NAND memory, reports ServeTheHome. The SSD is rated for up to one drive writes per date (1 DWPD) and is designed for mixed workloads.
The Samsung PM1743 drive will feature a PCIe Gen 5 x4 (single-port) or dual x2 (dual-port) interface and will come in an E3.S 1T form-factor (111.5 mm × 31.5 mm (L×W) designed to increase storage density in a server. There is no word about performance of the PM1743, but a theoretical peak throughput of a PCIe 5.0 x4 interface is about 15.7 GB/s.
In any case, the PM1743 should be faster than the PM9A3 (which is designed for data center applications and which is one of Samsung’s fastest PCIe 4.04 x4 SSDs) which offers an up to 6800 sequential read speed. As for power consumption, an E3.S 1T drive can consume up to 25W of power.
