Samsung XS1715 1.6TB 2.5-inch NVMe PCIe Enterprise SSD. Samsung has many firsts under their belt, with the world’s first 3D NAND and 3bit MLC (TLC) products leading the way. Pairing innovative hardware with a new interface technology capitalizes on the performance advantages of flash storage. Samsung also led the NVMe race with the XS1715, the industry’s first certified product (5/31/2013) on the UNH-IOL NVMe Test Consortiums Integrators List (IL).
NVMe standardizes interaction with non-volatile memory on the PCIe bus through an optimized register interface, command set, and feature set. We dive in deeper into the details in our Defining NVMe article. Intel brought the first NVMe products to the retail market with the Intel DC P3700, but the XS1715 has been in production behind the OEM curtain for a longer time.
The Samsung XS1715 is a 2.5″ NVMe PCIe SSD that comes in 400, 800, and 1.6TB capacities. Performance density is the most impressive aspect of the XS1715, it can deliver 750,000 random read IOPS and 115,000 write IOPS in an amazingly small 2.5″ 15mm package. It also offers a beefy 3,000 MB/s in sequential read speed and 1,400 MB/s of write performance. Samsung recently announced mass production of the SM1715 series, an NVMe SSD in the traditional HHHL form factor, and capacities up to 3.2TB courtesy of 3D V-NAND. The V-NAND powered SM1715 delivers a 10DWPD threshold, which is higher than the 5.6 DWPD (1.6TB model) from the XS1715’s 19nm Toggle NAND.
Dell currently sells the XS1715 in their popular PowerEdge R920 series as the PowerEdge Express Flash NVMe SSD. The XS1715 connects to a backplane and provides Dual-Port PCIe 3.0 x4 speed via the new SFF-8639 connector. Front bay access increases serviceability and brings hot-swapping capability to the PCIe interface. It also increases the potential number of NVMe drives deployed per server. Dell utilizes PCIe extender adaptors that allow four NVMe devices per motherboard PCIe slot. This maximizes performance and capacity density. Two of these extenders allow utilization of eight NVMe SSDs, and still leaves PCIe slots open for other hardware, such as networking and co-processors.
