The 2.5-inch WD S25 SAS drives offer the powerful combination of enterprise-class performance and reduced power consumption required for demanding high-performance computing and mission-critical environments.
The WD S25 SAS hard drives provide up to 300 GB of high performance storage suitable for both enterprise server and enterprise storage applications. The supersonic 6 Gb/s SAS interface enables optimum data reliability, availability and scalability. The small form-factor, 70 percent smaller than 3.5-inch drives, allows more system airflow resulting in lower cooling costs.
In an environment where space and power are limited, the WD S25 drives are an effective solution for high performance computing solutions such as power-constrained data centers, database transaction processing, and rack, tower, and blade servers.
Key Features
- Ultra fast – 6 Gb/s transfer rates and SAS 2.0 feature set delivering sustained sequential data rates of 128 MB/sec and high random IO rates.
