HPE 779168-B21 400GB SSD SAS 12Gbps SC SFF Overview

The HPE 779168-B21 400GB SSD SAS 12Gbps SC SFF Enterprise Solid State Drive represents Hewlett Packard Enterprise’s dedication to high-speed, reliable, and efficient data storage. Designed for demanding workloads and enterprise environments, this drive delivers superior read and write performance, durability, and scalability for modern data centers. Its SAS 12Gbps interface enhances throughput and reduces latency, ensuring consistent data delivery for mission-critical applications where performance and reliability are non-negotiable. Built to seamlessly integrate into HPE ProLiant and Synergy servers, this SSD ensures maximum uptime and predictable performance across a wide range of operational conditions.

Enterprise-Class Architecture and Reliability

The HPE 779168-B21 400GB SSD is built using enterprise-grade NAND flash technology that provides sustained performance and data integrity throughout its lifecycle. Unlike traditional hard drives, this SSD eliminates mechanical components, which significantly reduces failure rates and improves reliability. The small form factor (SFF) 2.5-inch design optimizes space utilization within dense server and storage infrastructures, making it an excellent choice for data centers where efficiency is essential. Its dual-port 12Gbps SAS interface provides full-duplex data transfer, offering balanced bandwidth for concurrent data streams and supporting continuous system uptime during drive failover operations.

Enhanced Data Protection and Power Efficiency

This enterprise SSD integrates advanced error correction, end-to-end data path protection, and power loss protection features that safeguard valuable information even during unexpected shutdowns. HPE’s proprietary firmware ensures consistent write performance and reduces latency spikes by efficiently managing NAND flash wear leveling. Power efficiency is another core aspect of the HPE 779168-B21 400GB SSD. The drive consumes less power compared to spinning disks, contributing to reduced cooling requirements and lower operational costs in data centers. Its design meets the rigorous demands of enterprise workloads, ensuring that the storage subsystem performs reliably under heavy I/O pressure while maintaining a low total cost of ownership.

Performance Optimized for Modern Applications

The HPE 779168-B21 400GB SSD delivers outstanding input/output operations per second (IOPS), which directly benefits enterprise applications that rely on fast data retrieval and high transaction throughput. Databases, virtualization platforms, and analytics workloads experience smoother and faster performance due to reduced latency and consistent read/write speeds. The SAS 12Gbps interface doubles the bandwidth of older 6Gbps SAS drives, enabling servers to handle massive amounts of concurrent data requests with ease. This capability makes the drive an ideal solution for workloads that demand real-time processing, such as online transaction processing (OLTP), virtual desktop infrastructure (VDI), and high-frequency trading systems.

Advanced SAS 12GBPS Interface and Connectivity

The HPE 779168-B21 400GB SAS SSD takes full advantage of the 12Gbps SAS interface standard, which provides superior data transfer rates and backward compatibility with 6Gbps systems. This ensures that enterprises can upgrade their infrastructure gradually without compromising on performance or compatibility. The SAS interface supports full-duplex communication, meaning that data can be read and written simultaneously, minimizing bottlenecks and optimizing throughput for multi-threaded applications. Dual-port functionality enhances fault tolerance and supports multipath I/O configurations, ensuring continuous access to data even if one path fails.

Optimized Throughput and Latency

With its high-speed interface, the HPE 779168-B21 400GB SSD delivers sustained sequential read and write performance that significantly exceeds that of traditional SAS HDDs. This enables faster access to frequently used data and allows servers to perform more operations in less time. The drive’s low latency architecture ensures that time-critical tasks complete faster, improving the overall responsiveness of enterprise systems. This makes it ideal for deployment in databases, data analytics engines, and virtualization clusters that require predictable and consistent I/O performance. The SAS protocol also supports advanced queuing and data integrity features, providing enterprises with a robust and scalable solution for their growing data storage needs.

Compatibility with HPE Ecosystem

Designed specifically for HPE servers and storage arrays, the HPE 779168-B21 integrates seamlessly with systems such as the HPE ProLiant Gen9 and Gen10 families.
