Hewlett Packard HP 128GB SATA SSD

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

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.
