Solidigm D7-P5810 PCIe Gen 4.0 Fast SLC U.2 Up to 800GB SSD for Write-Intensive Workloads

Solidigm announced the D7-P5810 SLC SSD for the data center market.

The D7-P5810 is a PCIe Gen 4.0 drive built on company’s 144-layer SLC 3D NAND.

An addition to the firm’s D7 Series, it is designed for high-endurance and extreme write-intensive workloads. This Storage Class Memory (SCM) SSD offers up to 50 Drive Writes Per Day (DWPD) for random, 65 DWPD for sequential, and up to 2x better performance than the competition ⁽¹⁾ for caching, HPC, data logging, journaling, and more, at less than ~20% of the cost of non-NAND SCM technologies.

SLC as storage accelerator
The D7-5810 is suited as a storage accelerator in front of highly dense capacity tiers (like QLC-based SSDs), adding significant benefit in the following use cases:

Metadata/logging: Placing performance-sensitive data such as metadata or logs on SLC can accelerate system performance by using SLC as a dedicated Write-Ahead Log in Ceph clusters, for example.

Caching: SLC SSDs can act as a write buffer or cache to help remove performance bottlenecks, improve application performance, and improve TCO.

Tiering: Data is written first to the SLC SSD so commits are fast, and subsequent reads are faster. As data becomes colder, it can be aggregated, compressed, and written in bulk to underlying higher-capacity QLC drives (like Solidigm’s D5-P5336) for space-efficient storage on that media. Write-shaping software such as Cloud Storage Acceleration Layer (CSAL), further delivers a solution that extends the density, TCO and sustainability value of QLC to more workloads.

“By introducing the D7-P5810, Solidigm has now further expanded its industry-leading endurance swim lane coverage. We are pleased to offer a new ultra-fast data center SSD with compelling specifications to serve customers’ very high write-intensive needs,” said Greg Matson, VP strategic planning and marketing.

Availability:

The D7-P5810 is available in 800GB (U.2 15mm form factor).
A 1.6TB version will be available in 1H24.
