Serial Attached SCSI (SAS) provides a superior storage solution. With some storage requirements escalating and others becoming more complex, factors such as flexibility, performance, increased reliability, greater density, security, scalability and accessibility are more critical than ever. Today's organizations consist of different kinds of environments. Enterprise data centers must be online almost 24X7, fulfill requests from numerous users simultaneously, and allow for constant growth and expansion while in operation. Other customer environments require high capacity storage and high data availability for low I/O environments. HP's portfolio of SAS drives meets all these demands.

HP 450GB 6G SAS 10K SFF (2.5-inch) SC Enterprise Hard Drive

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 <40% workload. Native Command Queuing (NCQ) to increase performance of SATA hard disks by optimizing the order in which received read and write commands are executed. Buffer Error Detection is used to protect the data in the drive buffer via parity or ECC. TLER purposely constrains the drive to report the error as soon as possible within 5 seconds vs. unlimited retries. Ships with a standard one year warranty.
* 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 <40% workload. Detects a specific temperature threshold, drive throttles performance to protect itself. Improved rotational vibration robustness for immunity to environmental rotational affects. Native Command Queuing (NCQ), Buffer Error Detection, Time Limited Error Recovery (TLER), Microcode Download and 3Gb/s compatibilty. Ship with a standard one year warranty.
* 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 <40% workload) of these drives will lessen the probability of drive failure. For high IOP's performance intense applications, mission critical applications or extreme environments HP recommends Enterprise Serial Attached SCSI (SAS) hard drives.

HP SAS Enterprise 10K rpm and 15K rpm hard drives deliver high performance solutions for hosting high transaction based applications. Available in HP hot plug carriers or non-hot plug. The HP SAS enterprise hard drives come in both 2.5in (SFF) and 3.5in (LFF) industry standard form factors and are available in a variety of capacity points to meet a wide range of requirements. The SAS interface was designed and engineered for high availability, enterprise-class data storage where performance, reliability and data integrity are crucial.
