The compact 2.5-inch design incorporates thermal considerations that ensure optimal operating temperatures even in high-density server configurations. Efficient heat dissipation maintains consistent performance while protecting the NAND flash and controller from thermal-related degradation.

480GB Capacity: Optimized for Enterprise Workloads

The 480GB capacity point represents a strategic balance between storage density, performance characteristics, and cost-effectiveness. This capacity is particularly well-suited for operating system installations, application binaries, frequently accessed datasets, and virtualization host environments.

Over-Provisioning and Usable Capacity

The HPE 831744-001 incorporates strategic over-provisioning, where a portion of the NAND flash capacity is reserved for background operations, wear-leveling, and garbage collection. This over-provisioning enhances performance consistency and extends the drive's endurance while delivering the advertised 480GB of user-accessible capacity.
