Product overview of the HPE P04539-H21

The P04539-H21 solid-state drive (SSD) is a high-performance storage device made by Hewlett Packard Enterprise (HPE) for use in server systems. This drive is designed for use in data-intensive applications that require fast read and write speeds, high capacity, and reliable data storage. In this article, we will examine the key features and specifications of the P04539-H21 Solid State Drive, including its capacity, interface, form factor, and data protection features.


The P04539-H21 SSD has a capacity of 6.4 terabytes (TB), making it a suitable choice for data centers and other applications that require large amounts of storage. This drive can store vast amounts of data, including business applications, user data, and multimedia content. With this capacity, the P04539-H21 SSD can provide high-speed access to critical data and improve system performance.


The P04539-H21 SSD uses the Serial-Attached SCSI (SAS) interface, which is a high-speed data transfer technology used in server systems. This interface provides fast data transfer rates of up to 12 gigabits per second (GBPS), allowing for rapid access to stored data. SAS technology is widely used in enterprise-class storage systems due to its reliability, scalability, and performance.

Form Factor

The P04539-H21 SSD has a 2.5-inch small form factor (SFF), which is a compact size that is commonly used in server systems. This form factor allows the drive to fit into a wide range of server chassis and storage systems, making it easy to integrate into existing infrastructure. The small form factor also enables high-density storage solutions, allowing for more storage capacity in less space.

Mixed Use

The mixed-use classification implies that the SSD is engineered to handle both read and write operations, making it versatile for a range of enterprise applications.

Multi-Level Cell (MLC) Technology

The P04539-H21 SSD uses Multi-Level Cell (MLC) technology, which is a type of NAND flash memory that allows for multiple bits of data to be stored in each cell. MLC technology provides high storage density and lower cost per gigabyte than other types of flash memory, such as Single-Level Cell (SLC) or Triple-Level Cell (TLC) technology. MLC technology also provides good performance and endurance, making it a popular choice for enterprise-class storage systems.

Robust Storage Capacity

The standout feature of the HPE P04539-H21 is its substantial storage capacity of 6.4TB. This makes it well-suited for businesses dealing with large datasets, databases, and other data-intensive applications.

SAS 12GBPS Interface for High-Speed Connectivity

The SAS interface is a key element contributing to the high-speed connectivity of this SSD. Operating at 12GBPS, it ensures efficient data transfer, a crucial factor in enterprise environments where speed is paramount.

Small Form Factor Design

The Small Form Factor design optimizes physical space usage within a server or storage array. This is particularly advantageous in environments where efficient space utilization is a priority.

Smart Carrier for Enhanced Manageability

The inclusion of a Smart Carrier enhances the manageability of the SSD. It provides additional features that streamline the installation process and contribute to the overall reliability of the storage solution.


HPE's commitment to reliability is evident in the design of the P04539-H21. Built with high-quality components and subjected to rigorous testing, this SSD is engineered to deliver consistent performance in demanding enterprise environments.


Endurance is a critical factor for enterprise-grade storage solutions. The HPE P04539-H21 demonstrated impressive endurance during extended testing, making it a reliable choice for sustained usage in environments with frequent data access.

Digitally Signed Firmware

The P04539-H21 SSD features Digitally Signed Firmware, which is a security feature that ensures the authenticity and integrity of the firmware on the drive. This feature helps protect against unauthorized access, malware, and other security threats that can compromise data stored on the drive. Digitally Signed Firmware is a critical feature for enterprise-class storage systems that require high levels of security and data protection.

Data Protection Features

The P04539-H21 SSD features several data protection features that help ensure the integrity and security of data stored on the drive. These features include Enhanced Power Loss Data Protection, which helps prevent data loss in the event of a power outage or other power-related issues. This feature ensures that data is written to the drive even in the event of a power failure, reducing the risk of data loss or corruption.

The P04539-H21 SSD also includes hardware-based encryption using Advanced Encryption Standard (AES) 256-bit encryption. This feature provides secure data storage and helps protect against data breaches and other security threats. Hardware-based encryption is more secure than software-based encryption and provides better performance, making it a popular choice for enterprise-class storage systems.
