The HPE 875593-B21 SSD is equipped with hot swap capability, enabling administrators to replace or upgrade drives without shutting down the server. This feature contributes to enhanced server uptime and flexibility in managing storage resources.

Solid State Drive Technology

Unlike traditional hard disk drives (HDDs), which use mechanical components to store and retrieve data, solid-state drives (SSDs) utilize flash memory technology. SSDs offer several advantages over HDDs, including faster data access, lower power consumption, and greater durability. By leveraging SSD technology, the 875593-B21 SSD delivers superior performance and reliability, making it ideal for demanding server applications.


The HPE 875593-B21 SSD has a storage capacity of 400 GB. This makes it suitable for servers that require high-capacity storage for mission-critical applications. The SSD uses Multi-Level Cell (MLC) NAND flash memory technology, which provides high performance and endurance. MLC NAND flash memory stores multiple bits of data in each memory cell, which allows for higher storage densities.


The HPE 875593-B21 SSD uses the PCIe 3.0 x4 interface. PCIe is a high-speed serial computer expansion bus standard that allows for fast data transfer rates between devices. PCIe 3.0 x4 has a maximum bandwidth of 32 Gbps, which is four times faster than the previous PCIe 2.0 x4 standard. This makes it ideal for high-performance storage devices like the HPE 875593-B21 SSD.

Form Factor

The HPE 875593-B21 SSD has a small form factor (SFF) of 2.5 inches. This makes it suitable for servers that require high-density storage in a small physical space. The small form factor also allows for easy installation and maintenance, as the SSD can be easily hot-swapped without disrupting server operations. The hot-swap capability also reduces downtime and improves server availability.

Digitally Signed Firmware

The HPE 875593-B21 SSD features digitally signed firmware, which provides an extra layer of security for data storage. Digitally signed firmware ensures that the firmware on the SSD has not been tampered with or modified. This helps to prevent unauthorized access to the data stored on the SSD and protects against data breaches. Overall, the HPE 875593-B21 SSD is a high-performance storage device designed for servers. It has a storage capacity of 400 GB and uses the PCIe 3.0 x4 interface, which allows for fast data transfer rates. The SSD has a small form factor of 2.5 inches and can be hot-swapped without disrupting server operations. It also features digitally signed firmware, which provides an extra layer of security for data storage. The HPE 875593-B21 SSD is made by HPE, a trusted provider of servers, storage, and networking solutions.
