Frequently asked questions

What are the performance specifications of the HPE 461201-B21 SSD?

The 461201-B21 delivers 100MB/s sequential read speed and 50MB/s write speed over a 1.5Gbps SATA interface. With 32GB capacity and MLC NAND technology, it provides reliable performance for boot operations and caching workloads in enterprise ProLiant servers, though it is not designed for high-throughput sequential I/O applications.

Which HPE ProLiant server generations support this drive?

The 461201-B21 is optimized for HPE ProLiant G6, G7, G8, and G9 generation servers. It features the NHP (non-hot-plug) designation, ensuring compatibility with HPE's enterprise storage subsystems and RAID controllers in these legacy and mid-generation platforms.

What is the physical form factor and how does it install?

This is a 2.5-inch small form factor (SFF) drive with 9.5mm height, designed for hot-plug installation in HPE ProLiant server drive bays. The hot-plug capability allows replacement without powering down the system, reducing maintenance downtime in production environments.

Is this drive suitable for high-performance database workloads?

The 461201-B21 is better suited for caching, boot acceleration, and log file storage rather than primary database storage. Its 100MB/s read and 50MB/s write speeds are adequate for I/O-intensive metadata operations but not for sustained high-throughput transactional workloads requiring NVMe or faster SAS SSDs.

What type of NAND memory does this SSD use?

The drive utilizes MLC (Multi-Level Cell) NAND technology, which balances cost and performance for enterprise applications. MLC NAND provides good reliability and endurance for mixed read/write workloads typical in server environments, though it has lower write endurance than SLC alternatives.

Can this drive be used as a replacement in newer ProLiant servers?

While physically compatible with 2.5-inch bays, HPE recommends validating compatibility with ProLiant G10 and newer servers. Newer generations prioritize NVMe and faster SAS SSDs; using legacy SATA drives may not be supported by current firmware or may not deliver expected performance benefits.
