XP3840SE70005 Seagate Nytro 5350H Gen4 NVMe PCIe SSD 3.84TB

Seagate XP3840SE70005 SSD Overview

The Seagate Nytro 5350H XP3840SE70005 Read-Intensive solid state drive positions itself as an enterprise-grade NVMe storage solution built to accelerate read-heavy data center workflows. With a 2.5-inch, 15 mm SFF profile and a PCIe® Gen4 ×4 NVMe interface, this 3.84TB model combines high sequential bandwidth with exceptionally low latency and massive IOPS capability to serve databases, caching layers, virtualization hosts, and software-defined storage nodes. The Nytro 5350 family is engineered to bring the next step of NVMe performance to dense server and storage appliance designs, while the XP3840SE70005 configuration specifically targets read-dominated application mixes where predictable, sustained throughput matters.

Architecture

At the heart of the Nytro 5350H is the PCIe Gen4 ×4 physical lane configuration paired with NVMe protocol efficiencies. This combination delivers a substantial uplift in raw bandwidth compared with PCIe Gen3 drives, enabling sequential read rates measured in multiple gigabytes per second and random I/O performance that scales into the millions of IOPS for small block reads. The drive utilizes Seagate-qualified 3D eTLC NAND flash, a multi-level enterprise-grade flash type that balances cost and endurance for read-intensive service profiles. Together, the Gen4 interconnect and advanced flash topology give system architects a tool for removing storage bottlenecks in front of CPUs and accelerators while keeping power draw and rack space consumption competitive.

Form Factor

The XP3840SE70005 comes in a 2.5-inch by 15 mm height form factor (SFF 15 mm), a standard footprint for enterprise hot-swap bays and high-density server sleds. Its physical dimensions and mounting layout make it compatible with U.2/U.3 cage designs and carrier adapters commonly used in enterprise chassis and storage shelves. The 15 mm thickness allows for additional internal thermal mass and more robust power delivery circuitry, attributes that help sustain the high sustained throughput rates expected from a Gen4 NVMe drive during prolonged read workloads. System integrators can therefore plan for straightforward mechanical deployment across blade servers, 1U/2U servers, and appliance enclosures without special modifications.

Performance

The Nytro 5350H series is explicitly tuned for read-intensive usage, and the XP3840SE70005 variant reflects that focus with quoted metrics that emphasize sequential and random read throughput and predictable quality of service. Measured sequential read throughput for 128KB transfers can reach into the multiple gigabytes per second range, while random read IOPS (4KB) can sustain very large values suitable for high-concurrency database and virtualization workloads. For environments where read latency is the gating factor — such as caching tiers, user profile stores, and read-optimized OLTP systems — the low-latency NVMe command set and Seagate’s firmware optimizations deliver more consistent response times compared with legacy SAS and SATA solutions. This predictable read performance reduces tail latency within clustered systems and enables higher consolidation ratios on compute hosts.

Measured

Published performance numbers for the Nytro 5350 family show sequential read speeds and sequential write capabilities that place the product among the leading Gen4 drives designed for enterprise service levels. Random read figures in the millions of IOPS translate into measurable application benefits: higher transaction throughput for databases, faster VM boot storms, lower latency for metadata servers in distributed file systems, and improved cache hit response for content delivery systems. The XP3840SE70005’s ability to sustain high read rates means fewer drives are required to meet a given read performance target, driving down rack-level power consumption and overall cost of ownership when measured across an entire deployment.

Reliability

Reliability is paramount in production data centers, and the Nytro 5350H family pairs endurance characteristics appropriate for read-intensive workloads with enterprise data protection features expected in modern SSDs. The use of 3D eTLC NAND and Seagate’s controller firmware yields endurance profiles that align with read-dominant duty cycles, while device-level features such as power-loss protection, end-to-end data path protection, error correction algorithms, and SMART telemetry provide layers of safety for stored data. For customers with regulatory or security needs, Seagate offers Self-Encrypting Drive (SED) options and models that meet FIPS/Common Criteria profiles, enabling encryption and secure erase capabilities that make decommissioning and data sovereignty simpler to manage. These characteristics collectively make the XP3840SE70005 a reliable component for enterprise storage tiers where read access is frequent and data integrity is non-negotiable.

Power

Power consumption and thermal management are vital considerations for dense NVMe deployments. The Nytro 5350H platform includes power and thermal management features designed to optimize energy efficiency while maintaining performance. Intelligent power states, dynamic thermal throttling, and firmware-level heuristics help the drive reduce power draw during idle phases and modulate throughput under sustained heavy use to prevent thermal excursions. Because rack power and cooling costs represent a sizable portion of data center operating expense, the XP3840SE70005’s efficiency characteristics directly impact rack-level economics. By consolidating capacity and performance into fewer drives that consume lower power per gigabyte of effective throughput, organizations can lower capex and ongoing facility costs.

Compatibility

Compatibility considerations for the XP3840SE70005 include ensuring that server motherboards, host bus adapters, and NVMe backplanes support PCIe Gen4 speeds and the U.2/U.3 or appropriate carrier interface in which the drive will be deployed. While the drive is backward compatible with Gen3 platforms, to extract full bandwidth and the highest IOPS numbers a Gen4 capable host is recommended. Integrating the drive into an existing fleet also involves aligning firmware versions, validating thermal profiles in targeted chassis, and confirming OS and driver support for enterprise NVMe features such as namespaces, namespace management, and vendor specific telemetry. Working closely with server vendors and storage platform providers helps avoid interoperability surprises and accelerates time to production.
