Introduction
:
HP Serial Advanced Technology Attachment (SATA) Hard Drives maximize the performance of HP Business PCs by
providing the technologies to meet your increasing storage demands with high-capacity drives offering superior reliability and
performance.
SATA provides faster data transfer speeds, better system cooling airflow, more bandwidth, more headroom for speed
increases in future generations and better data integrity. A next-generation technology, the SATA interface connects hard
drives to the PC platform 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. The HP Compaq 8300 Pro
Business PC supports the latest SATA 6.0Gb/s specification.
HP Drive Lock
HP Serial ATA Hard Drives offer enhanced security via a new Drive Lock. When enabled, this ATA security feature set
prevents software access to user data on the drive until one or two user-defined passwords are provided.
SMART IV 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 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.
Native Command Queuing
NCQ or Native Command Queuing 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), which 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. Enabling NCQ features in the hard drive requires AHCI support from the host
system BIOS, controller, and driver. AHCI support is typically implemented in RAID configurations.
Note: GB = 1 billion bytes. Actual available capacity is less.
Redundant Array of Independent Drives (RAID)
Flexible implementation:
DriveLock is supported while in RAID mode. Users can manage the DriveLock password from within F10 Setup.
Locked drives will be displayed as such in the RAID option ROM interface.
Hard drive information can be viewed within F10 Setup while in RAID mode. Previously, the hard drives will not appear
in Drive Configuration when switching to RAID mode.
DPS Self Test can be executed on physical hard drives while in RAID mode.
The RAID Setup Utility (accessed through CTRL-I) can be protected by the F10 Setup password.
NOTE:
RAID 1 is the only RAID configuration offered via factory configurations. The pre-configured systems:
Are only available on the SFF, MT and CMT form factors. The USDT does not support RAID as it does not allow for
more than one hard disk drive.
Are complete RAID systems and have both drives installed. If the CMT is configured with three hard disk drives, the
third drive is would be unpartitioned and not part of the RAID array
Have the necessary Option ROM configuration.
Are pre-loaded and pre-installed with all required Intel software.
Include a preinstalled operating system that is mirrored mode out of the box.
