480GB SATA III 3D NAND drive for consumer PCs

The Kingston A400 SA400S37/480G is a 2.5-inch internal solid-state drive built with 3D NAND flash memory. It delivers sequential reads up to 500 MBps and writes up to 350 MBps over the SATA III interface. The 7.00mm height suits standard desktop bays and many slim notebooks. It is rated for a 1,000,000-hour MTBF and operates from 0°C to 70°C.

Verify SATA III port and 7mm drive bay clearance

Confirm the motherboard or laptop provides a SATA III connector and a 2.5-inch bay that accepts a 7.00mm drive. The drive draws 0.195W idle and 0.279W average active power, with peaks of 0.642W read and 1.535W write. It withstands 2.17G operating vibration and 20G non-operating shock. No separate power adapter is required beyond the standard SATA power cable.

Replaces mechanical hard drives in older desktops

Swapping a spinning disk for this SSD yields roughly 10x faster data access, cutting boot and application load times. The upgrade is most worthwhile when the system uses a SATA III controller and has a 7mm drive slot. Available capacities include 120GB, 240GB and 480GB, so choose the size that matches the storage need and budget.
