HP Solid State Drive for Workstations
Overview
Introduction
Solid State Drives (SSDs) are fast becoming a real force with respect to storage in the computer industry. With no
moving parts, storage is no longer bound by mechanical barriers to higher performance. HP SSDs for workstations offer
overall performance typically beyond that of SAS 15k rpm HDDs (Hard Disk Drives).
SSDs should be considered for workstations with HDD bound workloads. For applications where 15k rpm HDDs deliver a
performance improvement over standard SATA HDDs, an HP SSD will likely deliver even better performance.
The Solid State Drives measure Access Time in microseconds (65 to 85) as opposed to the best HDDs (15k rpm) being
measured in milliseconds (~6ms); the SSD is about 70 times faster. In addition, the extremely high average sustained
read performance (up to 270MB/s) is considerably higher than the average sustained read performance of 15k rpm
HDDs available today (150MB/s to 205MB/s*). The result is a much higher performance potential. Random IOPs (I/O
OPerations per second) are in a class of their own, up to 20X faster than 15k rpm HDDs. This obviously helps with
database operations but it also helps with OS and application performance. Users experience faster boot times, faster
application loading and snappier system response.
SSDs help lower the acoustical emissions of the workstation. No moving parts means SSDs inherently have no
acoustical emissions. Furthermore, they consume much less power than Workstation class HDDs so less air is needed
for cooling. The result is lower system fan speeds and therefore, lower acoustics.
SSDs tend to be more rugged than hard drives with respect to shock and vibration because SSDs have no moving parts.
* Based on HP and third party tests.

QuickSpecs
HP Solid State Drive for Workstations
Overview
HP 160GB SATA X25-M SSD:
Up to 250MB/s sustained reads and up to 100MB/s sustained writes.
Access times of 65 microseconds (typical Read) and 85 microseconds (typical Write).
NOTE: The numbers above represent raw system performance. Actual performance in applications will typically be
lower.
Form Factor
These SSDs are 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.
The 160GB and 300GB MLC drives also benefits from the new Microsoft Windows 7 TRIM command. The TRIM
command is focused on maintaining MLC SSD write performance (inherently slower than SLC 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. Note that the TRIM command (available today via HP SoftPAQ and standard OS preload in ~August 2010). Note that TRIM is not supported on a RAIDed array.

Benefits
Higher overall performance than 15k HDDs based on random IOPs, sustained reads and sustained writes.
Lower systems level acoustical emissions 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.
