Solidigm D7 Data Center SSDs – The Industry's Most Advanced PCIe 4.0 Portfolio

Solidigm is adding two new product lines to its high-performing D7 Series of solid-state storage drives (SSDs) for cloud and enterprise workloads. The D7-P5520 and the D7-P5620 data center SSDs (formerly Intel®) are further expanding the industry's most advanced PCIe 4.0 SSD family. The D7-P5520 is designed for read-intensive and light mixed workloads and the D7-P5620 is designed for mixed workloads. Available in an extended range of form factors and capacities, the D7 Series SSDs offer accelerated performance and reduced total cost of ownership (TCO) by enabling a smaller storage footprint and lower power consumption.

The new D7 Series is the first product family that Solidigm is launching as a standalone company after SK hynix acquired Intel 's NAND and SSD business in December 2021. Solidigm's deep industry expertise and customer insights are reflected in the D7 SSD Series as they are designed with zero tolerance for data errors and have been tested to the industry's highest standards. 

Solidigm SSD D7 Series

The D7 Series comprises the industry's most advanced PCIe 4.0 SSD family of products given their capacity offerings, breadth of form factors and optimized performance capabilities. These SSDs are optimized for real-world workloads and reflect insights gained from deep technical engagements with leading cloud service providers, OEMs, and storage innovators. The D7-P5520 and the D7-P5620 are the culmination of these insights and of multiple 3D NAND and PCIe 4.0 generations, which enable us to deliver a best-in-class offering and a new paradigm in solid-state storage. Designed and tested with zero tolerance for data errors, consistently durable IOPS and QoS, and with near-zero lifetime performance degradation, they can be deployed with the utmost confidence.

D7 Series SSDs - Product Views


D7 Product Series Highlights

With Solidigm D7-P5520 and D7-P5620 SSDs performance has been significantly boosted across the board compared to the previous generation of PCIe 4.0 products. This enables workload acceleration in read-intensive and mixed applications.

Up to 42% higher 4K random reads, 17% higher 4K random writes, with up to 43% better latency generation to generation. It also delivers up to 40% better read responsiveness in the presence of write pressure as compared to the competition, a key consideration for real-world workloads.

Up to 56% 4K higher random reads, up to 53% higher random writes, with up to 76% better latency generation to generation.


Key Benefits of D7 Series

  • Accelerated performance across a range of workloads.
  • Reduced total cost of ownership (TCO) through the combination of higher performance and expanded capacities. For example, OEMs designing for a 10M IOPS 2U server can reduce the storage footprint up to 27% while reducing power consumption up to 28% generation over generation.
  • Deployment in a wide array of storage configurations, including 1U and 2U tiered and monolithic configurations in compute and storage servers. The drives are available with extended capacity ranges and in multiple form factors, including E1.L and multiple E1.S offerings.
  • Streamlined qualifications since Solidigm's D7-P5520 and D7-P5620 family of products share common NAND, firmware, and controllers across SKUs.
  • Quality and reliability are designed into these drives. For example, extra firmware checks are added to validate that data was saved accurately in the event of power loss. Additionally, the drives have been rigorously tested beyond industry specifications and common industry practices.

Target Application Examples

Cloud compute services are used across a range of scenarios such as data backup, disaster recovery, databases, email, and virtual desktop. These usages present a highly random, mixed workload environment valuing low latency to improve the user experience, and the Solidigm D7-P5520 delivers nearly 11% better response time than prior-generation drives. Server-based storage solutions using virtualization software are another common cloud storage workload. VMs in these workloads create a mix of reads and writes that can be random or sequential. Compared to prior-generation drives, the Solidigm D7-P5520 accelerates these workloads with up to 13% better random read IOPS and up to 11% better sequential write throughput.

As the name implies, general purpose servers (GPS) support a range of workloads that can span databases, email, unified communications, content delivery, and more. Given the nature of these servers, throughput and latency in a mixed environment is valued. Compared to the prior generation, the Solidigm SSD D7-P5520 accelerates 80/20 sequential/random read throughput up to 15% and reduces latency up to 13.5%. Data pipelines serving advanced workloads such as big data, machine learning, and AI are increasingly deployed in enterprises. I/O patterns vary widely through the pipeline phases, and the Solidigm D7-P5520 delivers with up to 7% better throughput for data-ingestion workloads, up to 6.7% read latency improvement in a 50/50 workload for data preparation, and up to 23.7% higher random read IOPS for training workloads compared to the prior generation.


ByteDance partnered with Solidigm early in product development and qualified the D7-P5520 with outstanding results before live deployment in March 2022. The drives are delivering a breadth of capacity and performance improvements over prior generations, which has allowed them to boost performance by 33% with dramatic TCO improvement for database and cloud software-defined storage. The D7-P5520 will also be used in ByteDance's public cloud services platform Volcano Engine.
