As AMD officially released the second generation EPYC processors, the popularity of PCIe 4.0 SSD in the server and data center also opened the curtain. Samsung immediately offered a big gift by announcing its first PCIe 4.0 SSD, PM1733, after AMD officially releases Rome-the second generation EPYC 7002 processor.

Recently, Samsung exposed the first PCIe 4.0 SSD and model is PM1733. The SSD has a 2.5-inch size, U.2 interface, a maximum capacity of 30.76TB, TLC NAND flash and the Samsung designed controller. In tests, the speed of Samsung PCIe 4.0 PM1733 reaches an astonishing 7.19GB/s while that of PCIe 3.0 was able to reach only 3.47GB/s. The gap between them is twice.

Samsung previewed the PM1733 as early as last Autumn and unveiled it at the product launch of second-generation EPYC processors, which will replace the PM1723b and makes the most of the ultra-high bandwidth advantage of PCIe 4.0 SSD.
Samsung PM1733 features its own developed controller with its own fifth-generation V-NAND flash and a single die capacity of 512Gb (64GB),which are available in two different styles: one is a 2.5-inch disk, with a dual U.2 interface, each of which is PCIe 4.0 x4 bandwidth and adds up to PCIe 4.0 x8. The maximum capacity of it is 30.72TB.

The other is the PCIe half-height and half-length expansion card, which is directly first to use PCIe 4.0 x8 bandwidth, with a maximum capacity of 15.36TB.

The current high-performance M.2 SSD is a PCIe 3.0 x4 channel with a bandwidth of 4GB/s. While the new generation PCIe 4.0 specification doubles the bandwidth, the speed of PCIe 4.0 x4 reaches 8GB/s and the speed of PCIe 4.0 x16 is as high as 64GB/s. Samsung PCIe 4.0 SSD PM1733 can provide up to 128 full-speed PCIe 4.0 connections in a single way. AMD also pointed out that applications, such as NVMe storage and networking, have high demand for bandwidth, where PCIe 4.0 SSD use. Samsung, Melanox, Xilinx, Broadcom and other manufacturers also display their PCIe 4.0 SSD and storage networking products in the spot.

In fact, there are now a large number of manufacturers in the market launched PCIe 4.0 SSD, including GigaByte, Galaxy, Pirate Ship, Patriot Memory, A-Data and so on, of which are all based on the Phison PS5016-E16 controller and are consumer-grade products. Interestingly, Samsung PM1733 is an enterprise-class SSD. There is no definitive information about when Samsung will launch the consumer-grade PCIe 4.0 SSD.

The PM1733 drive will be available industry-wide this quarter in both U.2 and HHHL variants, and will be backward compatible with PCIe Gen 3 architectures, providing exceptional flexibility for existing and future server applications.  The drive also features Dual Port capabilities to support storage as well as server applications.

In addition to Samsung’s PM1733 SSD, Samsung has provided its full lineup of RDIMM and LRDIMM DRAM products for AMD EPYC 7002 Series Processors. Using component architectures of 8Gb and 16Gb DDR4, Samsung is able to offer DIMM capacities ranging from 8GB to 256GB. With Samsung high density DIMMs, users can tap into as much as 4TB of memory per CPU.
