NVMe In The Enterprise: 3 GB/s Sequential Reads?
We've been patiently waiting for the first NVMe-based hardware since the specification was released in early 2011. As you can see from Samsung's roadmap, the wait is almost over.
Earlier this year, Samsung announced its XP941. While this M.2-compliant drive is connected through a two-lane PCI Express link, it still relies on AHCI. It's intended for Ultrabooks and may not be sold in retail channels. At least in the client space, we'll need to wait for the XP941's successor before getting introduced to NVMe.
The news is more promising on the enterprise side. Samsung announced its XS1715, which is NVMe-based.
In fact, the XS1715 is the first 2.5" SSD employing NVMe and an SFF-8639 connector (set to become the de facto for enterprise connectivity). The drive's high-density interface facilitates SATA, dual-port SAS, or third-gen PCIe x4 with accompanying reference clock and sideband signals. This product's specifications are truly amazing. With sequential reads rated at 3 GB/s and random reads in excess of 700,000 IOPS, it'll easily outpace most of today's PCI Express-based add-in cards.
All of that performance in a 2.5" enclosure with reportedly low power consumption should garner a lot of attention from enterprise customers. Unfortunately, Samsung was tight-lipped on availability and pricing.
