Frequently asked questions

What are the sequential read and write performance specifications for the HP 632504-B21?

The HP 632504-B21 delivers 320 MiB/s sequential read throughput and 100 MiB/s sequential write throughput (with write cache disabled). These specifications are optimized for enterprise workloads with mixed sequential and random I/O patterns. The drive achieves 40,000 IOPS random reads and 5,600 IOPS random writes, making it suitable for database and virtualization environments.

Which HP server platforms are compatible with the 632504-B21 SSD?

The HP 632504-B21 is designed for HP ProLiant DL and ML series servers, as well as HP BladeSystem c-Class blade servers. The 2.5-inch SFF form factor with SAS-6G interface integrates with HP's enterprise server storage subsystems. Compatibility extends to G4 and G7 generation ProLiant servers and later models supporting SAS-6G storage modules.

What memory technology does the 632504-B21 use and what are the endurance specifications?

The HP 632504-B21 utilizes MLC (Multi-Level Cell) NAND flash memory, which balances performance and cost-effectiveness for enterprise environments. MLC technology provides reliable performance for mixed workload deployments. The drive is rated for enterprise-class reliability with 3-year warranty coverage, suitable for data center environments with moderate to high I/O utilization.

What is the power consumption and thermal operating range of this SSD?

The HP 632504-B21 consumes 9W during operation, contributing to efficient data center power budgets. The drive operates reliably within a 0-60°C temperature range, supporting standard data center cooling infrastructure. This power efficiency and thermal profile make it suitable for dense server deployments and blade system environments.

How does the 632504-B21 compare to mechanical hard drives for enterprise applications?

The HP 632504-B21 SSD provides significant performance improvements over mechanical drives: 320 MiB/s sequential reads versus typical 150-200 MiB/s for enterprise HDDs, and 40,000 IOPS random reads versus 200-400 IOPS for 15K RPM drives. These improvements reduce database query latency, accelerate VM boot times, and improve overall application responsiveness in virtualization and database workloads.

What is the physical form factor and how does it integrate into HP server infrastructure?

The HP 632504-B21 features a standard 2.5-inch SFF (Small Form Factor) with 15mm height, designed for hot-plug installation in HP ProLiant and BladeSystem server storage bays.
