4XB7A74955 ThinkSystem DE Series 3.84 TB 1 DWPD 2.5″ SAS SSD Enterprise-Class Storage

The Lenovo 4XB7A74955 is a 3.84 TB internal 2.5″ SAS SSD engineered for the DE Series storage systems, such as DE4000H, DE6000H, and DE4200H (2U24 chassis). As a 1 Drive Write Per Day (1 DWPD) endurance-rated SSD, it is optimized for capacity-focused, read-intensive workloads—delivering dependable performance and ultra-high density in enterprise flash environments.

Features

Built to serve as a capacity-optimized tier within Lenovo entry-level hybrid or all-flash DE arrays, the 4XB7A74955 offers simplified deployment in space-constrained deployments without compromising reliability. With a firm endurance profile of 1 DWPD, this drive supports typical archival, analytics, and virtualized workloads efficiently. Data center managers benefit from hot-swap capability and enterprise SAS features like dual-port failover.

Advanced Options

Installed into a DE6000H or DE4000H system, these SSD enable up to 96 drive bays via expansion engines and offer support for advanced storage features such as Dynamic Disk Pools, encryption options, snapshots, and replication.

Product Key Features

  • 3.84 TB capacity in a 2.5″ SAS SSD with high storage density

  • 12 Gb/s SAS dual-port interface for reliability and scalability

  • 1 DWPD endurance rating—ideal for predominantly read workloads

  • Hot-swap and tool-less installation in DE-series enclosures

  • Designed for Lenovo DE-series arrays (DE4000H, DE6000H, DE4200H)

Reliability & Performance

Engineered for high availability and enterprise uptime, the SSD integrates dual-port SAS for redundant data paths, hot-swap support, and robust firmware. With tool-less tray compatibility for DE arrays, maintenance and upgrades are seamless. Despite its lower DWPD rating, reliability remains high under expected use patterns, making it suited for archival or large-scale capacity nodes in flash arrays. Provantage reports a 2.5 million‑hour MTBF and dense deployment capability in a 2U chassis

Key Features

  • 3.84 TB capacity in a compact 2.5″ form factor

  • 12 Gb/s SAS dual-port interface, hot-swappable

  • Mixed-use single DWPD endurance profile

  • Tray compatible with DE-series 2U24 SFF chassis

  • Tool-less servicing in high-density arrays

  • Optimized for capacity in hybrid or all‑flash environments

  • MTBF ~2.5 million hours

  • High drive count support: up to 24/2U chassis

  • Enterprise-class firmware with power-loss safeguards

  • Ideal for archival and read‑heavy deployments
