Product Overview

The Solidigm P5520 Series 3.84TB (Part Number: SSDPF2KX038T1Z) is a high-performance, enterprise-grade NVMe solid-state drive engineered to meet the demanding workload requirements of modern data centres, cloud service providers, and AI-driven infrastructure. Leveraging the PCIe 4.0 x4 interface and Solidigm's advanced 3D4 TLC (Triple-Level Cell) NAND technology, this 2.5-inch U.2 form factor drive delivers a compelling combination of massive capacity, industry-leading sequential throughput, and enterprise-class reliability. As organisations continue to scale their read-intensive and mixed-workload environments — from analytics pipelines and object storage to virtualisation and high-performance computing — the P5520 3.84TB positions itself as a foundational building block for next-generation storage infrastructure. Solidigm, formerly Intel's NAND memory and storage business, continues the legacy of precision-engineered enterprise SSDs with rigorous quality standards and broad platform compatibility, making the P5520 a trusted choice for enterprise procurement teams across the GCC and globally.

Key Features & Benefits

• PCIe 4.0 x4 Interface with NVMe 1.4 Protocol: Doubles the bandwidth available versus PCIe 3.0, enabling sequential read speeds of up to 7,000 MB/s — critical for latency-sensitive applications and data-intensive workloads that demand maximum throughput from storage subsystems.
• 3.84TB High-Density Capacity: A single drive delivers 3.84TB of usable enterprise storage, drastically reducing the number of drives needed per server node, lowering power consumption per terabyte, and simplifying rack-level capacity planning for hyperscale and enterprise deployments.
• 3D4 TLC NAND Technology: Solidigm's fourth-generation 3D TLC NAND delivers an optimised balance between cost-per-gigabyte, endurance, and raw performance — purpose-built for read-intensive and mixed enterprise workloads requiring sustained, predictable performance over long operational lifetimes.
• Enterprise-Grade Endurance (TBW): Rated at approximately 2,100 TBW (Terabytes Written), this drive is engineered to withstand sustained enterprise workloads with a 1 DWPD (Drive Writes Per Day) endurance rating over a five-year operational period, ensuring long-term investment protection.
• Power Loss Data Protection (PLDP): Integrated capacitor-based power loss protection ensures in-flight data is safely flushed to NAND in the event of sudden power interruptions, safeguarding data integrity in mission-critical enterprise environments without additional external infrastructure.
• End-to-End Data Path Protection: Features end-to-end data protection from host to NAND, including LDPC (Low-Density Parity-Check) ECC, ensuring data integrity across the entire read/write path and significantly reducing the risk of uncorrectable bit errors over the drive's operational life.
• Optimised Thermal Design: The P5520 incorporates dynamic thermal management and is rated for operating temperatures up to 70°C, enabling reliable performance in high-density rack configurations where thermal conditions may be elevated without requiring additional cooling infrastructure.
• U.2 2.5-Inch Form Factor: The industry-standard U.2 (SFF-8639) connector ensures broad compatibility with enterprise server platforms from leading OEMs including Dell, HPE, Lenovo, Supermicro, and others, enabling straightforward integration into existing server infrastructure.

Technical Architecture

The Solidigm P5520 is built upon Solidigm's proprietary 3D4 TLC NAND architecture — the fourth generation of their 3D NAND stacking technology — which stacks memory cells vertically to achieve higher bit density while maintaining tight control over cell-to-cell interference. This NAND generation delivers meaningful improvements in bit error rates compared to earlier planar and 3D generations, contributing to the drive's robust endurance and reliability profile.

At the heart of the P5520 is an enterprise-class NVMe controller paired with dedicated DRAM cache, enabling the drive to maintain stable queue depths and consistent latency profiles even under sustained mixed-workload conditions. The controller implements advanced wear-levelling algorithms, garbage collection routines, and over-provisioning management to extend NAND longevity and maintain consistent performance over the drive's rated lifetime.

The drive communicates via the NVMe 1.4 specification over a PCIe 4.0 x4 host interface, supporting features such as Namespace Management, End-to-End Data Protection (T10 DIF/DIX), Sanitize Operations, and multiple I/O queues (up to 65,535 queues with 65,535 commands per queue), enabling true enterprise-class parallelism and deep integration with modern operating system storage stacks.

Performance & Capacity

The Solidigm P5520 3.84TB delivers the following key performance metrics validated under enterprise workload conditions:

• Sequential Read Throughput: Up to 7,000 MB/s
• Sequential Write Throughput: Up to 3,600 MB/s
• Random Read IOPS (4K): Up to 1,000,000 IOPS
• Random Write IOPS (4K): Up to 200,000 IOPS
• Read Latency (QD1): Approximately 120 µs

• Usable Capacity: 3.84TB (formatted)
• Endurance: ~2,100 TBW / 1 DWPD over 5 years
• MTBF: 2,000,000 hours

These figures represent a substantial leap over PCIe 3.0-based predecessors, making the P5520 3.84TB an ideal upgrade path for data centre teams seeking to maximise storage performance per rack unit without expanding physical footprint.
