Overview of the HPE 875591-S21 SSD
The HPE 875591-S21 is a solid-state drive (SSD) that is designed for use in enterprise data centers. It is an internal drive that is capable of storing up to 1.92 terabytes of data. In this article, we will explain the technical specifications of this drive and discuss its intended use in enterprise data centers.
The HPE 875591-S21 is a Small Form Factor (SFF) drive that uses a Peripheral Component Interconnect Express (PCI-E) x4 interface. The PCI-E interface allows for high-speed data transfer between the drive and the rest of the computer system. The drive uses Non-Volatile Memory Express (NVMe) technology, which is a new protocol designed specifically for SSDs. NVMe technology allows for faster data transfer rates and lower latency compared to older protocols like SATA.
The HPE 875591-S21 is a Read Intensive drive, which means that it is optimized for read-heavy workloads. This type of drive is commonly used in data center applications where large amounts of data need to be accessed quickly. The drive has a sequential read speed of up to 3,000 megabytes per second (MB/s) and a sequential write speed of up to 1,900 MB/s. It also has a random read speed of up to 480,000 Input/Output Operations Per Second (IOPS) and a random write speed of up to 64,000 IOPS. These speeds make the HPE 875591-S21 one of the fastest SSDs on the market.
Read-intensive SSDs are designed for workloads that involve frequent access to stored data but require minimal write operations. They are optimized for read-heavy workloads and can handle large amounts of sequential reads with high performance and reliability.
Intended Use in Enterprise Data Centers
The HPE 875591-S21 is designed for use in enterprise data centers where high-performance storage is critical. It is intended to be used in servers, storage arrays, and other enterprise-class systems. The drive is particularly well-suited for read-heavy workloads such as databases, data warehousing, and virtual desktop infrastructure (VDI) applications. These applications require high-speed access to large amounts of data and can benefit from the HPE 875591-S21's fast read speeds.
In addition to its performance, the HPE 875591-S21 is also designed for reliability. It has a Mean Time Between Failures (MTBF) of 2 million hours, which means that it is expected to operate reliably for a long time. The drive also has built-in features like Power Loss Protection and End-to-End Data Path Protection that help to ensure data integrity and prevent data loss.
Overall, the HPE 875591-S21 is a high-performance SSD that is designed for use in enterprise data centers. It is optimized for read-heavy workloads and has fast read and write speeds. The drive is intended to be used in servers, storage arrays, and other enterprise-class systems that require high-speed access to large amounts of data. Its built-in reliability features make it a dependable choice for critical applications.

Looking for an SSD that offers superior data transfer rates and high performance?
Consider an NVMe SSD. NVMe (Non-Volatile Memory Express) is a protocol designed specifically for SSDs, enabling faster and more efficient communication between the storage device and your computer's processor.
Compared to traditional SATA SSDs, NVMe SSDs have a faster data transfer rate thanks to their PCIe (Peripheral Component Interconnect Express) interface, which can transfer data at up to 32GB/s. This means that NVMe SSDs can read and write data faster, resulting in faster boot times, application launches, and file transfers.
Another advantage of NVMe SSDs is their high performance. NVMe SSDs use the latest flash memory technology, which is faster and more reliable than traditional NAND flash. This technology allows NVMe SSDs to access data quickly, resulting in a more responsive system. NVMe SSDs also have a higher IOPS (Input/Output Operations Per Second) rate, which means that they can handle more simultaneous read and write operations.
NVMe SSDs are also designed to be more energy-efficient. They consume less power than traditional SATA SSDs, which means that they generate less heat and have a longer lifespan. NVMe SSDs also use less power when idle, which helps to extend the battery life of laptops and mobile devices.
But NVMe SSDs don't just offer faster data transfer rates. They also boast higher performance, thanks to the latest flash memory technology, which is faster and more reliable than traditional NAND flash. This technology allows NVMe SSDs to access data quickly, resulting in a more responsive system. NVMe SSDs also have a higher IOPS (Input/Output Operations Per Second) rate, meaning they can handle more simultaneous read and write operations.
NVMe SSDs are also designed to be more energy efficient than traditional SATA SSDs, consuming less power, generating less heat, and having a longer lifespan. This energy efficiency is particularly useful for laptops and mobile devices, where battery life is critical.
Available in various form factors such as M.2 and U.2, NVMe SSDs are suitable for different types of devices, from laptops and ultrabooks to desktops and workstations. No matter what kind of device you use, an NVMe SSD can offer superior performance and reliability.
In summary, if you're looking for a storage solution that offers fast data transfer rates, high performance, and energy efficiency, then an NVMe SSD is a great choice. With its advanced flash memory technology, high IOPS rate, and PCIe interface, an NVMe SSD can help boost your system's performance and responsiveness while consuming less power and generating less heat.
