SATA drives are our standard high bandwidth hard drive storage options; select models are also available with high performance 10K rpm rotation speeds. Storage capabilities range up to a massive 750 GB.

SATA Hard Drives maximize the performance of HP Workstations by providing the technologies to meet your increasing storage demands. These high-capacity drives offer superior reliability and performance. SATA is the latest generation ATA interface. It provides faster data transfer speeds, better system cooling airflow, more bandwidth, more headroom for speed increases in future generations and better data integrity helping to improve productivity. SATA point-to-point topology provides a direct path between the hard drive and the PC enabling easy aggregation of multiple hard drives into a single PC. This offers you the additional benefits of dedicated bandwidth, the ability to more easily identify device failures, and scalability. SATA 3.0 Gb/s Hard Drives offer data transfer rates of up to 3 Gb per second doubling your interface speed over SATA 1.5 Gb/s Hard Drives.

SMART IV technology
Self Monitoring Analysis and Reporting Technology (SMART) hard drive technology is allows hard drives to monitor their own health and to raise flags if imminent failures are predicted. If the drive determines that a failure is imminent, the SMART hard drive technology enables the intelligent manageability or management software to generate a fault alert. While the current versions of SMART hard drives do a good job monitoring the data on the hard drive media, the ever increasing emphasis on reliability and quality has promoted HP to implement SMART IV technology which constantly checks that the data flow from host interface to media and media to host interface is not compromised. This is accomplished by inserting a 2 byte parity code into every 512 byte block in the data path of the hard drive's Cache RAM. This unique parity checking performed by HP's SMART IV technology hard drives, allows for more complete error detection coverage encompassing the entire data path between the host and the hard drive.
Smart IV is also known as IOEDC: I/O Error Detection Code.

Restrictions on Hazardous Substances (RoHS)
RoHS is a European Union directive that requires OEM manufacturers compliance. The directive assures that hazardous substances are not contained within electronic equipment. Those substances include lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. Hewlett-Packard is committed to adhering to this directive.

Native Command Queuing
NCQ, or Native Command Queuing, is a capability of certain SATA drives, as designated in the product description. NCQ is a SATA protocol extension that allows the hard drive to have several write or read commands outstanding at the same time. In contrast, normal non-queued operation requires each command to be completed before the next command is issued by the host system. Queuing allows the drive to complete the commands in the order that allows for best overall throughput. It also involves an advanced method of transferring data to or from the host, called First Party Direct Memory Access (FPDMA), that allows the hard drive and the host controller to manage the data transfers for multiple outstanding commands, without involving the host processor. NCQ can contribute to better performance but the results are dependent on many factors, including the access patterns of the various applications and operating system functions that are initiating drive accesses. It requires support from the host system BIOS, controller, and driver in order to be useful. However NCQ-capable drives are compatible with host systems that do not include the support; the NCQ and FPDMA features are simply not used on those systems.
