HPE P04556-H21 internal solid

The Hewlett Packard Enterprise P04556-H21 is an internal solid state drive designed for enterprise server and storage applications requiring high reliability and consistent performance. This SSD features a 2.5-inch form factor with a SAS 12 Gb/s interface, ensuring compatibility with HPE ProLiant and Apollo server systems. With a storage capacity of 1.92 TB, it delivers sustained read speeds up to 1800 MB/s and write speeds up to 1050 MB/s, making it suitable for demanding workloads including database operations, virtualization, and data analytics. The drive incorporates enterprise-grade NAND flash memory with advanced wear leveling and error correction technologies, supporting a rated endurance of up to 10 full drive writes per day over its operational lifespan. The operating temperature range spans from 0 °C to 70 °C, with non-operational storage tolerance from -40 °C to 85 °C. Physical dimensions measure 100.45 mm in length, 69.85 mm in width, and 15 mm in height, with a weight of approximately 115 grams. The P04556-H21 includes power loss protection circuitry to safeguard data integrity during unexpected power interruptions and features self-monitoring capabilities with SMART attribute reporting. This drive is engineered for 24/7 operation in data center environments and supports hot-plug functionality for maintenance without system downtime. It maintains compatibility with HPE Smart Array controllers and is validated for use in HPE Gen10 and later server platforms. The solid state construction provides resistance to vibration and mechanical shock compared to traditional hard disk drives, while consuming typically 5-7 W during active operation and less than 1 W in standby mode. This model succeeds previous generation HPE enterprise SSDs with improved performance characteristics and enhanced reliability features for modern data center requirements.
