Seagate Exos X14 ST12000NM0008 12 TB Hard Drive – 3.5″ Internal – SATA (SATA/600)

The Seagate Exos X18 12TB ST12000NM0008 is a high-capacity, enterprise-class hard drive designed for demanding data centers and storage environments. Built to handle vast amounts of data, it offers superior reliability, performance, and endurance for use in large-scale storage systems. Below is a detailed description of its features, specifications, and benefits:

1. Capacity:

• 12TB Storage: With a massive 12TB of storage capacity, the Seagate Exos X18 ST12000NM0008 is designed for high-capacity storage applications, such as data center workloads, cloud storage, and archiving solutions. This high-capacity feature allows businesses to store vast amounts of data in a single, reliable disk without the need for multiple drives.

2. Form Factor and Interface:

• Form Factor: The drive is a standard 3.5-inch form factor, which makes it compatible with most enterprise-grade servers and storage arrays that support this physical format.
• Interface: It utilizes the SATA 6Gb/s interface, ensuring fast data transfer speeds and compatibility with a wide range of enterprise systems. While SATA interfaces are generally slower than SAS, the Exos X18 compensates with its larger cache and optimizations for sequential read/write operations.

3. Performance:

• Rotational Speed: The Exos X18 operates at a 7200 RPM (revolutions per minute), providing a balance of high capacity with decent performance. While 7200 RPM hard drives are slower than 10K or 15K RPM models, they offer better capacity per dollar and lower power consumption, making them ideal for cold storage and near-line applications.
• Cache Memory: The drive is equipped with a substantial 256MB cache, helping to improve overall read and write speeds. The cache serves to buffer data, enhancing performance during burst activity and streamlining the access to frequently used data.
• Average Latency: The average latency of the drive is around 4.16 ms, which is typical for 7200 RPM drives, providing sufficient speed for most enterprise applications that don’t require ultra-low latency.

4. Data Integrity and Reliability:

• MTBF (Mean Time Between Failures): The Exos X18 drive has an impressive 2 million hours MTBF, which is a key indicator of its reliability and long service life. This makes it suitable for mission-critical applications in enterprise environments where uptime is crucial.
• Annualized Failure Rate (AFR): The AFR is rated at 0.35%, meaning it is expected to fail less than 1 time in every 250 drives per year. This is a strong indicator of the drive’s overall durability and suitability for heavy-duty usage in data centers.
• End-to-End Data Protection: The Exos X18 features Seagate’s advanced end-to-end data protection, which ensures that data integrity is maintained from the host to the drive and back. This feature protects against data corruption during transfer, helping to avoid costly data loss and downtime.
• Advanced Power Loss Protection: The drive includes a built-in power loss data protection mechanism that ensures data is preserved during unexpected power outages or system shutdowns.

5. Energy Efficiency and Power Consumption:

• Low Power Consumption: The Exos X18 is designed to be energy-efficient, with a typical power consumption of 7.6W during active use and 5.6W during idle. This makes it an attractive choice for large-scale deployments where power efficiency can significantly reduce operational costs.
• Idle Power: The drive features an Idle Power of 5.0W which helps in reducing energy consumption when the drive is not being actively accessed, thus contributing to lower total cost of ownership (TCO) over the drive’s lifespan.
