## Long description

The HPE 400 GB 2.5" SATA III SSD is a high-performance solid-state drive engineered specifically for demanding server and workstation environments. Utilizing SLC NAND Flash technology, this drive provides superior reliability, enhanced endurance, and consistent data throughput, making it a robust solution for enterprise-level data management. Its 2.5-inch form factor ensures compatibility with a wide range of server storage platforms, offering a seamless upgrade path from traditional mechanical hard drives to high-speed flash storage.
Advantages
This solid-state drive offers significant improvements in system responsiveness by providing lower latency and higher random read input/output operations per second compared to traditional rotating hard disk drives. The use of SLC technology ensures a high level of data integrity and extended operational lifespan, which is critical for mission-critical server applications. Furthermore, the drive operates with greater energy efficiency, contributing to reduced power consumption and lower heat generation within the server chassis, ultimately supporting a more stable and cost-effective IT infrastructure.
Suitable for
Enterprise server storage systems
High-performance workstation applications
Environments requiring high random read IOPs
Database management and transaction processing
This drive may not be suitable for applications requiring massive bulk storage capacity, as its 400 GB limit is optimized for performance-critical data rather than archival storage. Additionally, it is designed specifically for compatibility with HP ProLiant servers and may not be the ideal choice for consumer-grade desktop computers or non-enterprise hardware configurations.
Key specifications
Capacity: 400 GB
Form factor: 2.5-inch

How to use
Installation of the HPE 400 GB SSD should be performed by qualified technical personnel in accordance with the server manufacturer's guidelines. The drive is designed to be mounted into compatible 2.5-inch drive bays within HP ProLiant servers or storage enclosures. Ensure the server is powered down or follow the hot-plug procedure if the specific server model supports it. Once physically installed, the drive should be initialized and configured through the server's RAID controller or operating system disk management utility to ensure optimal performance and data redundancy.
What to consider before purchase
Verify compatibility with your specific HP ProLiant server model
Ensure your storage controller supports SATA III 6 Gbit/s interfaces
Assess whether the 400 GB capacity meets your specific workload requirements
Confirm if your server chassis supports 2.5-inch SFF drive form factors
Usage recommendations
