SEAGATE ST8000NM0085 8 TB 3.5″ Internal Hard Drive-Brand New

The ST8000NM0085 is a high-performance 8TB enterprise hard disk drive (HDD) manufactured by Seagate, specifically designed for demanding business applications. It is part of Seagate’s Exos X16 series and is engineered to meet the needs of data centers, servers, and large-scale storage environments. Here is a detailed breakdown of its features and capabilities:

1. Capacity and Storage

• Capacity: The ST8000NM0085 provides an 8TB storage capacity, making it ideal for environments requiring large amounts of data storage. With 8TB of space, it is suitable for high-demand applications such as cloud storage, video surveillance, backup solutions, and archival systems.

2. Form Factor

• Form Factor: The ST8000NM0085 comes in a 3.5-inch form factor, a standard size for enterprise HDDs. This makes it compatible with most server and storage rackmount systems, as well as legacy systems designed for 3.5-inch drives.

3. Performance Specifications

• Data Transfer Rate: The drive offers a high sustained data transfer rate, with the ability to reach up to 250 MB/s. This ensures fast data access and retrieval, making it suitable for applications where high throughput is critical, such as database management and video streaming.
• Spindle Speed: The ST8000NM0085 operates at 7,200 RPM (Revolutions Per Minute), which is a good balance between performance and energy efficiency. While 10,000 RPM or 15,000 RPM drives exist, 7,200 RPM is often sufficient for most enterprise storage workloads, providing reasonable speed with lower heat generation and power consumption.

4. Interface and Compatibility

• Interface: The drive uses the SATA III (Serial ATA 6Gb/s) interface, which is widely supported in enterprise storage systems and servers. SATA III provides a fast data connection that supports high-speed data transfer between the hard drive and the rest of the system.
• Backward Compatibility: The ST8000NM0085 is also backward compatible with previous SATA versions (SATA II and SATA I), though the maximum performance would be limited by the capabilities of the interface.

5. Cache Memory

• Cache Size: The drive is equipped with 256 MB of cache memory. Cache helps in speeding up access to frequently used data by storing it temporarily, reducing latency and improving overall system performance.

6. Reliability and Durability

• MTBF (Mean Time Between Failures): With an impressive 2.5 million hours MTBF, the ST8000NM0085 is built for durability and long-lasting performance. This is especially important for enterprise applications where minimizing downtime is critical.
• Annualized Failure Rate (AFR): The drive is rated with a low AFR of 0.44%, meaning the likelihood of failure over a one-year period is low. This ensures the drive will continue to operate reliably for long periods, which is critical in high-demand environments like data centers and enterprise storage systems.
• Shock Tolerance: The drive has been engineered to handle shock up to 70G for non-operating conditions, which makes it suitable for environments where physical movement may occur, such as in rack-mount storage systems.

7. Energy Efficiency and Power Consumption

• Power Consumption: The drive is designed with energy efficiency in mind. It operates with a low power draw in idle and active modes, making it an excellent choice for energy-conscious data centers and environments that need to optimize power usage. Its typical power consumption in idle mode is around 5.4W, and around 8.0W when active.
• Power Loss Protection: While the ST8000NM0085 does not feature on-board power loss protection (like some SSDs or high-end enterprise HDDs), it is designed for stable power conditions, and data loss due to power failure is unlikely under normal operating conditions.

8. Data Security and Integrity

• Seagate Secure: The ST8000NM0085 supports Seagate Secure technology, offering self-encrypting drive (SED) capabilities. It features hardware-based encryption (AES 256-bit), helping secure data at rest, ensuring that sensitive information is protected against unauthorized access.
• Advanced Error Correction: The drive also incorporates Advanced Format technology (4K sectors), and error correction technologies to ensure data integrity during read and write operations. This minimizes the chances of data corruption, particularly important for critical applications in enterprise environments.

9. Workload and Application Suitability

• Workload Rating: The ST8000NM0085 is rated for a 180 TB/year workload, meaning it can handle 180 terabytes of data being written to the drive every year. This makes it suitable for workloads like file and object storage, cloud applications, and media streaming, where high write operations are common.
• Applications: It is optimized for a range of applications, including:
  • Cloud Storage: Perfect for large-scale cloud storage platforms.
  • Data Centers: Suitable for storage systems requiring high capacity, low-latency, and high reliability.
  • Surveillance Systems: Can handle the constant write-intensive demands of video surveillance systems.
  • Backup and Archiving: Ideal for high-capacity backup systems that need reliable long-term storage.

10. Environmental Considerations

• Operating Temperature: The ST8000NM0085 can operate within a temperature range of 5°C to 60°C (41°F to 140°F), allowing it to function in environments with varying temperatures.
• Non-Operating Temperature: The non-operating temperature range is between -40°C to 70°C (-40°F to 158°F), ensuring the drive can withstand transportation or storage in diverse environmental conditions without damage.
