HP 256 GB TLC M.2 SATA-3 Solid State Drive Features
Smart technology

Higher overall performance than 15k HDDs based on random IOPs, sustained reads and sustained writes

Budget-conscious innovation

Lower systems level acoustical emissions than systems with HDDs, especially 15k rpm HDDs

World-class design and support

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.)

[1] For storage drives, GB = 1 billion bytes. Actual formatted capacity is less.
