The Seagate Nytro 5550H SSD with 800 GB storage capacity is a 6,3 cm ( 2,5 inch )-SSD designed for use in data centres and server-based environments. It features a PCI Express 4.0 interface with x4 data lanes and supports the NVMe standard, enabling direct and efficient communication with the host system. The SSD is designed for Mixed Use (MU) workloads, meaning applications with mixed read and write traffic, and is particularly suitable for server virtualisation, OLTP databases, software-defined storage, and all-flash arrays. The use of 3D eTLC memory chip technology ensures a balanced combination of performance, capacity, and lifespan. The SSD is designed for use in Universal systems, implying broad compatibility with various server and storage architectures.

Applications

The Nytro 5550H is designed for use in modern data centres where high I/O performance, low latency, and high reliability are required. It is particularly suitable for applications requiring fast data access, such as databases, caching solutions, or virtual machines. The SSD supports both Windows and Linux operating systems, enabling easy integration into existing IT infrastructures. The high IOPS performance and low latency ensure consistent quality of service (QoS), which is important for critical applications.

Features and Specifications in Detail

The SSD offers a read speed of 7400 MB/s and a write speed of 1900 MB/s, representing a significant performance improvement over older SATA SSDs. For random access, it achieves 1.7 million IOPS for reading and 140,000 IOPS for writing (4KB, QD64), ensuring high parallelism and fast response times. The read latency is 75 µs and the write latency is 12 µs, enabling fast data processing. The Uncorrectable Bit Error Rate (UBER) is less than 1 per 10^17 bits read, ensuring very high data integrity. The Mean Time Between Failures (MTBF) is 2,500,000 hours, indicating high reliability.

Technology Explained Simply

The use of PCI Express 4.0 with x4 lanes enables high bandwidth, which is necessary for the fast transfer of large data volumes. The NVMe standard optimises communication between the SSD and the host, as it operates directly on the PCIe bus, thus minimising latency. The 3D eTLC technology offers higher storage density than conventional 2D flash chips, allowing more storage capacity in a smaller form factor. The SSD is designed for an average operating voltage of 12 V, with an average power consumption of 11 W and 5 W in standby. These values are typical for high-performance SSDs and suitable for operation in server environments.

Compatibility and Accessories

The SSD is designed for use in data centre environments and is compatible with Windows and Linux operating systems. The use of PCIe Gen4 NVMe enables direct integration into systems supporting this interface. The SSD is housed in a 6,3 cm ( 2,5 inch ) form factor with a height of 14.9 mm, making it suitable for standard server and rack systems.

Mounting and Installation

The SSD is designed for use in servers and storage systems that support the 6,3 cm ( 2,5 inch ) form factor. Installation is typically done using a bracket or tray system provided in the respective server system. The SSD is suitable for hot-swap functions, meaning it can be replaced during operation without shutting down the server. This increases availability and simplifies maintenance.

Operational Advantages

The Nytro 5550H offers high I/O performance with low latency, leading to improved system responsiveness. The high MTBF and low UBER ensure high reliability and data integrity. Support for Windows and Linux, along with compatibility with PCIe Gen4 NVMe, enables flexible integration into existing IT infrastructures. The SSD is designed for use in data centres, where high demands on performance, reliability, and maintainability exist. The low latency and high IOPS performance help avoid data bottlenecks and improve the quality of service.
