Product Overview for the HPE P40480-B21 400GB Solid State Drive

The HPE P40480-B21 400 Gigabytes (GB) Serial-Attached SCSI (SAS) 24 Gigabytes Per Second (GBPS) Write-Intensive Small Form Factor (SFF) Triple Level Cell (TLC) Solid State Drive (SSD) is a cutting-edge storage solution designed to meet the demanding requirements of modern server environments. This comprehensive guide will provide an in-depth exploration of the technical specifications, performance attributes, use cases, and the overall impact this SSD can have on server systems.

Understanding SAS Technology

Serial-attached SCSI (SAS) is a high-performance storage interface that brings reliability and speed to server storage solutions. The HPE P40480-B21 leverages the SAS interface, which is known for its superior performance, scalability, and compatibility with enterprise-level applications. The 24 Gigabytes Per Second (GBPS) speed ensures rapid data transfer, making it a robust choice for servers handling intensive workloads.

Capacity and Form Factor

With a storage capacity of 400 Gigabytes (GB), the HPE P40480-B21 strikes a balance between high-performance storage and efficient space utilization. The Small Form Factor (SFF) design ensures a compact footprint, making it suitable for servers with limited physical space. This versatility allows for optimal data center configurations and efficient use of available resources.

Write-Intensive Application

The term "Write-Intensive" in the context of SSDs refers to their suitability for workloads that involve frequent write operations. The HPE P40480-B21 is specifically engineered for write-intensive applications, making it ideal for scenarios where consistent and sustained write performance is crucial. This includes environments where data is frequently updated, such as database servers and content delivery systems.

Triple-Level Cell Technology

The HPE P40480-B21 incorporates Triple Level Cell (TLC) technology, a type of NAND flash memory known for its high-density storage capabilities. TLC SSDs store three bits of data per cell, providing a cost-effective solution for applications that require large storage capacities. This technology, combined with the SSD's high write endurance, makes it well-suited for write-intensive workloads.

Use Cases

The HPE P40480-B21's unique combination of high-performance features and write-intensive design makes it suitable for various server use cases. Here are some scenarios where this SSD can excel:

  • Database Management: Database servers, particularly those handling frequent write operations, benefit from the HPE P40480-B21's write-intensive design. It ensures consistent and reliable write performance, improving overall database responsiveness.
  • Content Delivery Systems: In content delivery systems where data is frequently updated and written, the HPE P40480-B21's high write endurance and write-intensive capabilities contribute to efficient content delivery. It ensures that updated content is delivered promptly to end-users.
  • Financial Applications: Financial applications often involve extensive write operations, such as transaction logging. The HPE P40480-B21's write-intensive design makes it suitable for financial environments where data accuracy and consistency are paramount.
  • Virtualization: In virtualized environments where a mix of read and write operations is common, the HPE P40480-B21's balanced performance is advantageous. It ensures responsive performance for virtualized workloads, contributing to an optimal virtualization experience.


Ensuring compatibility with existing hardware and software infrastructure is crucial when integrating new storage solutions. The HPE P40480-B21 is engineered to be compatible with a wide range of servers and storage controllers. This compatibility ensures a seamless integration process, allowing businesses to upgrade their storage infrastructure without significant disruptions.

Reliability and Durability

Reliability is a key consideration in server storage solutions, where downtime can have significant consequences. The HPE P40480-B21 is built with durability in mind, leveraging solid-state technology that eliminates the mechanical failures associated with traditional hard drives. This enhances overall system reliability, reducing the risk of data loss and ensuring continuous operation.

Security Features

Data security is a top priority in server environments, especially considering the sensitive nature of the information stored. The HPE P40480-B21 incorporates advanced security features to safeguard data integrity and prevent unauthorized access. These security measures may include hardware encryption, secure erase capabilities and built-in data integrity checks.


While high-performance storage solutions are essential, cost-effectiveness is also a critical factor for businesses. The HPE P40480-B21 strikes a balance between performance and cost, offering a competitive solution for organizations looking to enhance their server storage without breaking the budget. The long-term durability and reliability of SSDs contribute to a lower total cost of ownership over the product's lifespan.
