HP SATA drives are designed for the reliability and mass storage 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. These high-capacity drives provide the lowest cost per gigabyte to our customers. 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 small form factor (3.5-inch) and large form factor (2.5-inch) and ship with a standard one-year warranty.
