Product Overview

The Solidigm P5520 Series 3.84TB (Part Number: SSDPF2KX038T1OZ) is a high-performance, enterprise-grade NVMe solid-state drive purpose-built for the most demanding data centre environments. 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 the capacity, endurance, and throughput required by modern hyperscale, cloud, and enterprise IT deployments. With OPAL 2.0 self-encrypting drive (SED) capability, the P5520 ensures data-at-rest security compliance without sacrificing performance, making it a compelling choice for regulated industries including finance, healthcare, and government sectors across the GCC and globally.

Solidigm, the enterprise storage brand spun out of Intel's NAND business, continues a legacy of innovation in flash storage. The P5520 sits at the heart of their read-optimised portfolio, striking an ideal balance between raw throughput, endurance, and cost-per-gigabyte efficiency. For IT procurement teams and data centre architects in Dubai, the UAE, Saudi Arabia, and across the wider Middle East, the P5520 represents a proven, scalable foundation for next-generation storage infrastructure.

Key Features & Benefits

• PCIe 4.0 x4 Interface with NVMe 1.4 Protocol: Doubles the bandwidth ceiling compared to PCIe 3.0, enabling sequential read speeds of up to 7,000 MB/s and sequential write speeds of up to 3,600 MB/s — critical for latency-sensitive enterprise applications and high-throughput data pipelines.
• 3.84TB Usable Capacity in a 2.5-Inch Form Factor: Delivers dense, rack-efficient storage with a high capacity-per-slot ratio, reducing the number of drives needed to reach petabyte-scale deployments and lowering total infrastructure cost.
• 3D4 TLC NAND Flash Technology: Solidigm's fourth-generation 3D NAND provides improved die density, better power efficiency per gigabyte, and robust cell reliability optimised for enterprise read-intensive duty cycles over multi-year operational lifetimes.
• OPAL 2.0 Self-Encrypting Drive (SED): Hardware-based AES-256 encryption with Trusted Computing Group (TCG) OPAL 2.0 compliance enables transparent, high-performance data-at-rest protection, supporting instant secure erase and integration with enterprise key management systems without CPU overhead.
• High Random Read IOPS — Up to 1,000,000 IOPS: The P5520's NVMe command queue depth and PCIe 4.0 architecture sustain up to 1 million random 4K read IOPS, making it ideal for database query acceleration, analytics, and virtualisation host storage.
• Power Loss Protection (PLP): Onboard capacitors and firmware-level PLP mechanisms ensure in-flight data integrity during unexpected power events, a non-negotiable requirement for enterprise production environments.
• End-to-End Data Path Protection: Error detection and correction across the full data path — from host interface through DRAM cache to NAND — minimises the risk of silent data corruption in mission-critical storage tiers.
• Optimised for Mixed Read-Write Workloads: While read-optimised by design, the P5520 handles mixed enterprise workloads gracefully, sustaining consistent latency under queue depth variation and workload burstiness.

Technical Architecture

The Solidigm P5520 is built on Solidigm's 144-layer 3D4 QLC-adjacent TLC NAND, stacked using advanced 3D cell architecture to maximise die density while preserving the endurance and reliability characteristics demanded by enterprise SLAs. The drive utilises a high-performance NVMe controller with multiple internal cores managing parallelism across NAND channels, delivering consistent performance under sustained queue depths typical of server workloads.

The drive communicates with the host via the PCIe 4.0 x4 lane interface, supporting the NVMe 1.4 command set including Namespace Management, Directive Send/Receive, and Persistent Memory Region (PMR) features. An onboard DRAM cache — sized appropriately for the 3.84TB capacity — accelerates metadata operations, address mapping, and write buffering, contributing to the drive's low-latency read response profile.

The 2.5-inch U.2 (SFF-8639) physical form factor with a 15mm Z-height ensures broad compatibility with enterprise server platforms, storage enclosures, and JBOFs (Just a Bunch of Flash) from all major OEMs. The firmware stack includes advanced wear-levelling algorithms, dynamic over-provisioning management, and adaptive thermal throttling to maintain performance within safe operating envelopes even in thermally constrained chassis.

These specifications position the P5520 among the top-tier read-optimised NVMe SSDs available in the enterprise market, making it particularly well-suited for workloads where read bandwidth and IOPS density are the primary bottleneck. The PCIe 4.0 interface ensures the drive will remain performant even as host platform bandwidth increases with next-generation server CPU releases.
