Form Factor
These SSDs are 7mm SFF (Small Form Factor, 2.5") drives, which are mounted in a removable 3.5" Frame. The SSD can be mounted
in either a standard 3.5" bay or in a SFF, 2.5" bay by removing the 3.5" frame.
Intelligent System Maintenance
SSDs emulate HDDs such that the operating system thinks it is talking to a hard drive. However the physical data mapping is quite
different. In fact the SSD intelligently manages the physical location of data on the drive in the background via wear leveling
algorithms that maximize the life of the SSD. The extremely fast access times of SSDs permit the SSD to move the data around as
needed for wear leveling without impacting the performance. The net result is that defragmenting is not needed and
defragmenting will not improve the performance. In fact, defragmentation should be turned off.
SSDs use the TRIM function to improve endurance. The TRIM command is focused on maintaining MLC SSD write performance by
erasing no longer used (released) logical blocks (aka files deleted from the Windows recycle bin) from the SSD automatically in the
background. Most configurations with Win7 and Win8, including single SSD, RAID 0, and RAID 1, will provide support for TRIM.
Optional controllers, including the SAS controllers supported on Workstations, do not provide support for TRIM when used in a
RAID configuration, but do enable TRIM in non-RAID configurations. For additional information regarding TRIM support, please
contact HP technical support. Use HP Performance Advisor software to check the actual usage / wear level of the device.

Benefits
Higher overall performance than 15k HDDs based on random IOPs, sustained reads and sustained writes.
Lower system level acoustic noise than systems with HDDs, especially 15k rpm HDDs
More rugged than HDDs with respect to shock and vibration
Typical wall power savings relative to a 15k drive is ~10W/drive (based on drive idle power and power supply at 85%
efficiency. Active drive power deltas are slightly larger.)
Lower system maintenance because there is no need to defragment the drive
NOTE: Some operating systems such as Microsoft Vista automatically schedule defragmenting sessions. Shutting off automatic
defragmenting for the SDD will save both time and energy.
Compatibility
SSDs are supported on all Z-Workstations. Check individual workstation platform Quickspecs for confirmation.
If an HP Solid State Drive is purchased as an After Market Option, the kit will include a mounting bracket for use in the standard
3.5" HDD Bays. If it is for use in an Optical Bay, one of the following mounting brackets will be needed.
