TOSHIBA MG08-D SERIES ENTERPRISE CAPACITY HDD

（2） Core reliability indicators

The MG08-D series is designed according to the highest reliability standards of enterprise level, with the following key indicators:

Mean Time to Failure (MTTF): 2000000 hours (calculated based on 8760 hours per year, 7 x 24 hours of operation), which means that under normal usage conditions, the average failure interval of the hard drive exceeds 228 years, ensuring long-term stable operation;

Annual Failure Rate (AFR): 0.44%, much lower than consumer grade hard drives, reducing maintenance costs and failure risks in data centers;

Unrecoverable error rate: For every 10 ¹⁶ bits of data read, the number of errors does not exceed 10, ensuring the integrity of data storage;

Loading/Unloading Times: 600000 times, suitable for scenarios where the hard drive frequently starts and stops for a long time;

Annual rated workload: 550 TB/year (workload defined as the amount of data written, read, or verified by the host system through commands), supports continuous operation for 7 × 24 hours, and is suitable for high load and high concurrency usage requirements in data centers;

Reliability supplement: When the surface temperature of the HDA (hard drive component) of the hard drive continues or exceeds 40 ° C for a long time, it may reduce the reliability of the product, and reasonable heat dissipation needs to be ensured in the design of the computer room.

Applicable scenarios and application value

（1） Core applicable scenarios

Mid line/Nearline Business Critical Workload: As an "intermediate layer" storage between high-speed performance disks and archive cold data disks, it balances performance and capacity and is suitable for critical data storage such as financial data, customer information, business system logs, etc. that require fast access and large capacity requirements.

Tier 2 Business Critical Servers and Storage Systems: Suitable for non core but important business servers such as office automation servers, mail servers, small and medium-sized database servers, providing stable storage support.

High Capacity per Spindle Beneficial Server: By using a single disk with high capacity (up to 8 TB), it reduces the number of hard drives in the server, lowers hardware procurement costs, energy consumption, and server room space occupation, making it suitable for scenarios such as high-capacity distributed storage and cloud storage nodes.

Capacity optimized data center storage system: designed to meet the capacity layering requirements of data centers, it is used to store massive amounts of non real time access data, such as backup data, archived data, video surveillance recordings, etc., achieving efficient utilization of storage resources.

Applications and virtual machine monitoring programs that rely on legacy 512 native sector technology: The 4 TB version supports 512n sector technology, seamlessly replacing traditional hard drives and ensuring smooth migration and stable operation of older systems (such as early Windows Server and specialized industrial software).

（2） Application value

Strong compatibility: Through multi option design of interfaces and sector technology, it adapts to new and old IT infrastructure, avoiding system reconstruction costs caused by storage device upgrades for enterprises;

Total cost optimization: High capacity design reduces the number of hard disk deployments, low power consumption reduces long-term operating energy consumption, low failure rate reduces maintenance costs, and achieves cost optimization throughout the entire lifecycle of hardware procurement, operation, and maintenance;

Data security assurance: Some models support SIE instant erase and SED self encryption functions, meeting enterprise data security compliance requirements and reducing data leakage risks;

Stability and availability: Enterprise level reliability indicators (2 million hours MTTF, 0.44% AFR) and 7 × 24-hour operation capability ensure continuous and stable operation of business systems, reducing business interruptions caused by storage failures.
