Solidigm releases D7-P5810 - fast SLC SSD for write-intensive workloads

Published by


Solidigm has launched the Solidigm™ D7-P5810, an ultra-fast Single-Level Cell (SLC) SSD designed specifically for write-intensive workloads within the data center sector. This product marks Solidigm's inaugural foray into the realm of SLC solid-state storage drives (SSD). The D7-P5810 operates on the PCIe Gen 4.0 platform and is constructed using Solidigm's established 144-layer SLC 3D NAND technology.

This addition bolsters Solidigm's existing D7 Series lineup and is engineered to accommodate high-endurance and exceptionally write-intensive tasks. This Storage Class Memory (SCM) SSD delivers impressive performance metrics, offering up to 50 Drive Writes Per Day (DWPD) for random operations, 65 DWPD for sequential tasks, and demonstrating a 2X performance improvement over competing alternatives for functions like caching, high-performance computing (HPC), data logging, journaling, and more. Remarkably, this comes at a cost that is less than approximately 20% of non-NAND SCM technologies.

The D7-P5810 fulfills the role of a storage accelerator, particularly when positioned in front of high-capacity tiers, such as QLC-based SSDs. It proves advantageous in various scenarios, including:

  • Metadata and logging applications, where performance-critical data like metadata or logs can benefit from SLC as a dedicated Write-Ahead Log within Ceph clusters.
  • Caching purposes, with SLC SSDs serving as efficient write buffers or caches, eliminating performance bottlenecks, enhancing application performance, and optimizing Total Cost of Ownership (TCO).
  • Data tiering, where data is initially written to the SLC SSD for expedited commits, followed by faster subsequent reads. As data cools down, it can be aggregated, compressed, and written in bulk to underlying higher-capacity QLC drives (e.g., Solidigm’s D5-P5336) to achieve space-efficient storage on that media. Additionally, write-shaping software like Cloud Storage Acceleration Layer (CSAL) further augments density, TCO, and sustainability advantages for QLC in diverse workloads.

Greg Matson, VP of Strategic Planning and Marketing at Solidigm, noted, "With the introduction of the D7-P5810, Solidigm has expanded its industry-leading endurance coverage. We are delighted to offer an ultra-fast data center SSD with compelling specifications tailored to meet the demands of high write-intensive workloads."

The D7-P5810 is currently available in an 800GB U.2 15mm form factor, with a 1.6TB version slated for release in the first half of 2024.
