XS3840SE70055 Seagate Nytro 3350 3.84TB SAS 2.5" Server SSD

High-Performance 2.5" SAS Enterprise SSD featuring consistent latency and SED security with the XS3840SE70055

The XS3840SE70055 is a 3.84TB 2.5" internal SAS enterprise SSD engineered for server boot volumes and read-centric application tiers where predictable service times matter more than peak burst performance. By pairing a SAS interface with 3D TLC NAND, the XS3840SE70055 aligns well with mainstream dual-socket CPU platforms and virtualisation hosts that require stable storage behavior across mixed I/O profiles.

In PCIe- and GPU-dense systems, SAS SSDs such as the XS3840SE70055 preserve valuable PCIe lanes for accelerators and high-speed networking while still delivering up to 1,100 MB/s sequential read and strong 4K responsiveness for shared datastores. The drive’s 1 DWPD endurance over 5 years (7,000 TBW) supports moderate write activity typical of VM consolidation, log-heavy services, and analytics pipelines that prioritize consistent latency. As a Self-Encrypting Drive, the XS3840SE70055 integrates TCG Enterprise and 256-bit AES to simplify secure decommissioning and meet data-at-rest requirements without adding CPU overhead.

Why Choose the XS3840SE70055?

The XS3840SE70055 provides an enterprise-appropriate density-to-performance balance for SAS backplanes, enabling straightforward scaling of capacity within existing storage enclosures and server bays. With predictable power characteristics and a proven endurance profile, the XS3840SE70055 supports reliable operation in always-on data centre environments and reduces risk when standardising boot and application tiers across large fleets.

Seagate designs the Nytro portfolio with a focus on sustained QoS, controlled firmware behavior, and compatibility with modern server storage standards. This engineering approach helps maintain consistent performance under mixed workloads while supporting operational requirements for security, lifecycle management, and long-term deployment planning.

Key Applications:

• Server boot volumes
• Read-centric application tiers
• Virtualisation VM datastores
• Mixed I/O database and analytics
• Secure data-at-rest deployments
