Lenovo 4XB7A90049 - ThinkSystem M.2 ER3 480GB Read Intensive SATA 6Gb SSD

Overview:

The Lenovo 4XB7A90049 is an enterprise-grade M.2 Solid State Drive (SSD) part of the ThinkSystem ER3 series, specifically engineered for server boot functions and read-intensive data storage. Utilizing the 6Gbps SATA interface, this drive provides a reliable, non-hot-swap (NHS) storage solution that balances endurance with high-speed data access for operational stability in high-density rack and tower servers.

This drive is primarily deployed as a primary boot volume for Lenovo ThinkSystem servers, including the SE, ST, and SR series. It solves the critical requirement for high-endurance boot media that can handle consistent read operations without the latency of traditional mechanical drives. It is ideal for hypervisor hosting, OS installation, and general data logging where 1 Drive Write Per Day (DWPD) meets the workload profile.

The 4XB7A90049 features advanced end-to-end data protection and Power Loss Protection (PLP) to ensure data integrity during unexpected outages. While optimized for server environments, it should not be utilized in write-heavy database clusters or high-transactional environments that exceed its rated endurance specifications.

Key Features:

• 480GB capacity delivers optimized space for enterprise OS and boot volumes.

• SATA 6Gbps interface provides reliable throughput for server workloads.

• 1 DWPD endurance rating ensures 5-year stability for read-intensive use.

• Self-Encrypting Drive (SED) support secures sensitive data-at-rest.

• Power Loss Protection (PLP) prevents data corruption during power events.
