Performance Characteristics of the EMC 118000181 SSD

High-Speed SAS 12Gbps Interface

The SAS 12Gbps interface represents a significant leap in data transfer rates over previous generations, enabling faster communication between the drive and host system. This interface is designed specifically for enterprise environments, offering improved bandwidth and reduced latency compared to SATA interfaces. The EMC 118000181 utilizes this interface to provide rapid access to stored data, making it well-suited for applications that demand high I/O operations per second (IOPS).

Impressive IOPS and Throughput Metrics

The EMC 118000181 excels in both random and sequential data operations. With a random read performance reaching up to 190,000 IOPS and random write speeds up to 68,000 IOPS on 4KB blocks, this drive is optimized for transaction-heavy applications such as databases, virtualized workloads, and online transaction processing (OLTP) systems. Additionally, its sequential read and write speeds of 940 MB/s and 790 MB/s respectively allow for efficient handling of large file transfers and streaming workloads.

Balanced Mixed-Use Performance

Unlike drives optimized solely for read-heavy or write-heavy workloads, the EMC 118000181 is tailored for mixed-use environments. This means it maintains consistent performance even when read and write operations occur simultaneously, a critical feature for enterprise systems running diverse applications concurrently. The endurance rating of 3 DWPD ensures reliability over prolonged periods of continuous usage.

Durability and Reliability in Enterprise Environments

Advanced Endurance with 3 DWPD

Drive Writes Per Day (DWPD) is a key metric indicating how many times the total capacity of an SSD can be rewritten daily during its warranty period without performance degradation. The EMC 118000181 supports 3 DWPD, making it an excellent choice for environments where data is frequently updated or rewritten, such as transactional databases, real-time analytics, and caching layers.

Industry-Leading MTBF of 2 Million Hours

The Mean Time Between Failures (MTBF) for this model is an impressive 2 million hours, reflecting the high level of engineering and quality control involved in its manufacturing. This reliability metric indicates that the drive is built to withstand the rigorous demands of enterprise workloads, minimizing downtime and maintenance costs.

Robust Data Integrity and Error Correction

EMC’s SSDs incorporate sophisticated error detection and correction algorithms that help protect against data corruption. These technologies include advanced ECC (Error Correction Code) and end-to-end data path protection, ensuring the integrity of your data even under heavy load or adverse conditions.

Form Factor and Physical Design

Compact 2.5-Inch Size for Flexible Deployment

The EMC 118000181’s 2.5-inch form factor makes it compatible with a wide range of enterprise server racks and storage arrays. This compact size enables efficient use of space within data centers, allowing for dense storage configurations without sacrificing airflow or cooling capabilities.

Internal Drive for Seamless Integration

Designed as an internal SSD, this drive easily integrates with existing server and storage infrastructures. Its standardized interface and form factor simplify upgrades or expansions, reducing downtime and installation complexity.

Enterprise Data Storage

The EMC 118000181 is engineered to meet the high-performance and reliability demands of enterprise storage environments. It is suitable for:

• High-throughput databases
• Virtualized servers and desktop virtualization (VDI)
• Big data analytics platforms
• Cloud infrastructure
• Business-critical applications requiring consistent low latency

Virtualization and Cloud Computing

In virtualized and cloud environments, storage demands fluctuate rapidly as virtual machines spin up and down, often requiring simultaneous read and write operations. The EMC 118000181’s mixed-use design and endurance make it ideal for these dynamic workloads, providing fast access speeds without sacrificing drive longevity.

Transactional Workloads and OLTP Systems

Transactional systems, including online transaction processing (OLTP), demand storage devices that can handle frequent random read/write I/O operations with minimal latency. The drive’s high IOPS and endurance ensure smooth performance for applications like e-commerce platforms, financial services, and inventory management systems.

Comparing EMC 118000181 to Other Enterprise SSDs

Advantages Over SATA-Based SSDs

While SATA SSDs offer a cost-effective upgrade over traditional hard disk drives, they are limited by their interface speed capped at 6Gbps. The EMC 118000181 with its SAS 12Gbps interface doubles this bandwidth, providing a significant performance boost in environments where speed is critical.

MLC NAND Flash Benefits

Compared to Single-Level Cell (SLC) NAND, MLC provides greater storage density at a lower cost per gigabyte while maintaining adequate endurance and performance for most enterprise applications. This balance makes the EMC 118000181 a compelling choice for mixed workloads that require reliable speed and capacity.

Endurance and Reliability in Context

Some enterprise SSDs utilize Triple-Level Cell (TLC) NAND for higher capacities at lower prices but often sacrifice endurance. The EMC 118000181’s MLC NAND coupled with a 3 DWPD rating strikes a middle ground, delivering solid reliability and lifespan suitable for mission-critical operations.

Firmware Updates

EMC regularly provides firmware updates to optimize performance, enhance security, and extend the drive’s lifespan. Administrators can use management tools to monitor drive health, track wear levels, and perform predictive failure analysis to proactively maintain storage infrastructure.
