- As part of its commitment to hardware, software, and solution innovation, HP is proud to introduce this breakthrough platform configuration stability to HP Workstation customers. HP Stable & Consistent Offerings are built on the foundation of a carefully chosen set of hardware and software designed and tested to work with all HP Workstation platforms through their end of life.- SAS (Serial Attach SCSI) is a high performance architecture designed for high performance servers. 15K rpm SAS drives spin faster than 10k drives and are available with 6Gb/s (Gigabit/sec) transfer rates* offering even more performance than 10K rpm drives. SAS drives require an available SAS storage controller. Note: 15K rpm drives may be audibly noticeable.

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 $/GB 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 small form factor (2.5-inch) and large form factor (3.5-inch) and ship with a standard one year warranty.Entry SATA drives offer customers the lowest acquisition cost, features include the following:• Reliability for non-mission critical entry server environments, appropriate for Midline SATA offers customers the lowest $/GB drives and increased features over Entry SATA• Increased reliability of approximately two times Entry drive reliability based on SATA Applications• With the attractive low acquisition cost and high capacity points of SATA drives it is important to understand the appropriate applications where SATA drives should be used. Proper usage (IE
