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.
