HP SATA drives are designed for the reliability and larger capacities demanded by today's entry server and external storage environments. The SATA portfolio is categorized into two categories: Entry (ETY) and Midline (MDL) drives. HP SATA Entry drives are the lowest unit-cost solution for entry-level servers. HP SATA Midline drives are designed with economical reliability and performance for external storage, backups and archival applications. Both Entry and Midline SATA drives provide the best price advantage for non-mission critical applications with low workloads of 40% or less. HP SATA drives are available in both 3.5 and 2.5 form factors and ship with a standard one year warranty. All HP hard drives pass a rigorous qualification process, which ensures that every HP drive is proven to perform in your HP ProLiant server. Before final certification, all HP SATA hard drives are optimized for compatibility and functionality, including support of SMART and HP Systems Insight Manager.
