Intel 320 Series 120GB SATA II SSD

The Intel 320 Series is a 2.5-inch internal solid-state drive with 120GB capacity. It uses MLC NAND flash memory and a SATA II interface. The drive targets consumer desktops and notebooks seeking reliable storage upgrades.

SATA II interface limits throughput

Sequential reads reach up to 270MBps and writes up to 130MBps over the SATA II link. The 3Gbps bus caps real-world transfer rates below faster SATA III alternatives. Buyers must confirm their system provides a SATA II or SATA III port.

Fits standard 2.5-inch drive bays

The drive draws 100mW idle and 150mW active, leaving headroom for tight power budgets. It withstands 1500G shock and offers 1.2 million hours MTBF. No extra cables or adapters are needed beyond a standard SATA data and power connection.
