SATA (Serial ATA) Hard Drives for HP Workstations

SATA 7200 rpm drives are our standard high bandwidth hard drive storage options; most workstation models are also available with high performance 10K rpm rotation speeds. Storage capabilities range up to a massive 1000 GB (1 TB).

The 7200 rpm HDDs (Hard Drives) are all 3.5" drives. The 10K rpm drives come in SFF (Small Form Factor, 2.5") drives and SFF drives in 3.5" frames; the appropriate choice depends on the available drive bay in a supported chassis.

SMART technology
Self Monitoring Analysis and Reporting Technology (SMART) hard drive technology 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 intelligent manageability or management software to generate a fault alert. While the legacy 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 prompted 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 parity code into every 512 byte block in the data path of the hard drive's Cache RAM. This 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 modern SATA drives. 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.

NOTE: GB = 1 billion bytes. Actual available capacity is less.

320GB SATA 7200 rpm 3Gb/s 3.5" HDD

Most SATA Hard Drives are compatible with all of the current HP xw-series and Z-series Workstations (check the individual workstation QuickSpecs for current hard drive compatibility information).

When ordering drives as After Market Options for use in an optical bay, order an appropriate bracket as follows:

• HP Z-series Workstations
  • 3.5" drive bracket for HP Z400, Z600 and Z800, HP Optical Bay HDD Mounting Bracket-BLK-for WKS, HP Part Number NQ099AA
  • 2.5" (SFF) bracket for Z600 and Z800, HP 2.5in HDD 2:1 Optical Bay Bracket, HP Part Number FX615AA
• HP xw4600 or xw6600 Workstation: 3.5" drive bracket, HP Optical Bay HDD Mounting Bracket, HP Part Number DY659AA.

NOTE: Not all hard drive models are available in all regions.
