Building from multiple generations of PCIe 4.0 and deep industry insight, this is the industry’s most advanced PCIe 4.0 portfolio with performance tuned for real-world applications. They efficiently accelerate compute and storage workloads in cloud and enterprise across a breadth of 1U and 2U server configurations. Designed and tested with zero tolerance for data errors [2] and consistently durable performance, [3] they can be deployed with the utmost confidence.
TLC 3D NAND SSD series highlights
Compared to the previous generation of PCIe 4.0 products, performance has been significantly boosted across the board, enabling workload acceleration in mixed and read-intensive applications.
Read intensive
Write intensive
Form factor and capacity expansion enable server modernization opportunities spanning a broad range of 1U and 2U
With NAND media, firmware, and controllers common to all SKUs in the family, customers have an opportunity to ease qualifications across form factors and capacities, given the possibility of data sharing.
Advanced feature set
Building on our previous generation PCIe 4.0 data center SSDs, the Solidigm D7-P5520 and D7-P5620 offer a wide range of new features (in addition to features supported by the Solidigm D7-P5510) that are essential to building modern data centers. Some of the notable drive features include:
Optimized for real-world cloud and enterprise storage workloads
Overall performance improvements combined with our deep, industry-wide technical insight deliver performance tuned for the real world, helping to efficiently accelerate compute and storage workloads for cloud and enterprise.
Examples of unlocking cloud storage workloads—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%6 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. [7]
Examples of unlocking enterprise storage workloads—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%. [8] 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. [9]
TCO savings opportunities
Whether solving for storage-footprint optimization or for performance density, expanded capacity ranges and accelerated performance enable a range of cost-saving opportunities.

Deploy with confidence
Solidigm D7-P5520 and Solidigm D7-P5620 drives are designed and tested with a passion for—and a relentless focus on—quality, reliability, and consistency, so you can deploy them with confidence.
Quality and reliability designed into every drive:
- In-house design or design control of all critical components
- Robust third-party component quality assurance (QA) program
- Enhanced Power Loss Management firmware checks to ensure data accuracy [12]
Drives validated and tested above and beyond:
- Data reliability: Data reliability is enhanced on multiple levels with PLI testing that simulates real-world conditions, UBER testing to 10x beyond JEDEC specification, and SDC testing at the highest levels in the industry.2
- Drive reliability: Proven reliability delivers AFR significantly better than JEDEC in high-volume manufacturing. [13] Robust RDT and margin-corner testing helps ensure drives perform reliably in real-world conditions.
- Consistency: Up to 90% IOPS consistency and <0.3% IOPS variability provides consistent performance over life of the drive [3]

Notes
[1] Comparing Solidigm™ D7-P5520 to key competitors where Solidigm is the only supplier offering E1.L and co-leads U.2 and E1.S capacity ranges. Also factors in read responsiveness under write pressure comparing D7-P5520 and similar competitor drive using Intel® Server Board M50CYP2SB2U, Intel® ICE LAKE - P5 4GXRAV D, Number of CPUs: 2, Number of Cores: 36, DRAM: DDR4 – 64GB, OS: CentOS Linux release 7.5.1804, Kernel Version: 3.10.0-862.el7.x86_64 using FIO for workload measurement. Other factors considered are the additional measures implemented by Solidigm in designing in for quality and reliability and product testing (see footnotes 2 and 12).
[2] SDC modeling and testing: Solidigm drives are tested to 1E-17 under a full range of conditions and cycle counts throughout the life of the drive, which is 10x higher than 1E-16 specified in JEDEC Solid State Drive Requirements and Endurance Test Method (JESD218) (see jedec.org/standards-documents/focus/flash/solid-state-drives). RD: Typical reliability demonstration test involve 1K drives for 1K hours to levels down to 1E-18. Solidigm drives are tested at the neutron source at Los Alamos National Labs to measure SDC susceptibility to 1E-23 with modeling to 1E-25. In three generations of testing at Los Alamos, equivalent to more than 5M hours of operational use, zero SDC errors have been detected on Solidigm drives, and no evidence of other suppliers testing at the facility has been observed.
