The 846434-B21 is a Solid State Drive (SSD) designed and produced by Hewlett Packard Enterprise (HPE). This drive is specifically created for servers, providing reliable and fast data storage. The drive has a capacity of 800 Gigabytes (GB) and uses the Serial-Attached SCSI (SAS) interface, which provides high data transfer rates of up to 12 Gigabits per second (Gbps). In this article, we will discuss the features and benefits of the 846434-B21 SSD.

• The 846434-B21 SAS 12GBPS SSD has a storage capacity of 800 GB, which is ample space for data storage for server applications. This capacity allows the drive to store a significant amount of data, including operating systems, applications, and user files. With this amount of storage, the drive can handle large workloads with ease.
• The drive is designed in the Small Form Factor (SFF) with a 2.5-inch size. This form factor is ideal for server applications, as it enables more drives to be placed in a server's drive bays. The SFF design also provides a higher storage density, which allows for more storage capacity in a smaller space.

• SAS Interface: The 846434-B21 utilizes a Serial-Attached SCSI (SAS) interface, providing a robust and high-speed connection to the server. SAS is known for its reliability and performance, making it a preferred choice for enterprise-grade storage solutions.
• Data Transfer Rate: With a 12 Gigabits Per Second (GBPS) data transfer rate, this SSD ensures swift and efficient data access. The 12GBPS speed aligns with the demands of modern applications, enabling quick read and write operations crucial for server workloads.
• Mixed Use Classification: Designed for Mixed Use (MU), this SSD is versatile enough to handle a variety of workloads. Whether it's read-heavy, write-heavy, or a balanced mix, the 846434-B21 is engineered to perform consistently across different usage scenarios.

• Importance of Hot Swap: One standout feature of this HPE SSD is its Hot Swap capability. In server environments, the ability to replace or add storage devices without shutting down the system is crucial for maintaining uninterrupted operations. Hot Swap ensures that the SSD can be replaced on the fly, minimizing downtime and enhancing overall system reliability.
• 2.5-inch Form Factor: The 2.5-inch form factor adds to the versatility of this SSD, allowing it to fit seamlessly into servers that accommodate this size. The compact design doesn't compromise performance, making it an ideal choice for modern data centers where space optimization is key.
• Interface and Speed: The 846434-B21 SSD uses the Serial-Attached SCSI (SAS) interface, which provides a reliable and efficient connection to the server. SAS is a high-speed interface that provides fast data transfer rates of up to 12 Gigabits per second (Gbps). This high speed allows the drive to transfer data quickly, which is essential for server applications that require quick access to data.

The 846434-B21 SSD is a mixed-use drive, which means it is designed for both read and write-intensive workloads. This design makes the drive ideal for server applications that require both high read and write speeds. Mixed-use drives provide a balance between performance and endurance, making them ideal for use in data centers and server applications.

• The 846434-B21 SSD is designed to be reliable and durable, making it an ideal choice for server applications. The drive uses solid-state technology, which is more reliable than traditional hard drives. SSDs have no moving parts, which means they are less prone to mechanical failures.
• The 846434-B21 SSD also has a Mean Time Between Failures (MTBF) of 2 million hours, which indicates the drive's reliability. MTBF is a measure of a drive's reliability and indicates how long the drive is expected to last before it fails.
