480GB SATA SSD for everyday computing

The Kingston A400 is a 2.5 inch internal solid state drive built with 3D NAND and a SATA III interface. It targets desktop and notebook users who want faster start-up, quicker application loading and snappier file transfers without moving to a newer platform. The drive has no DRAM cache and is rated for 160TB total bytes written with a 1,000,000 hour MTBF.

SATA III caps sequential speed at 500 MBps read

The SATA III interface limits maximum sequential throughput to 500 MBps read and 450 MBps write regardless of the NAND technology inside. Power draw stays low at 0.195W idle, 0.279W average active, 0.642W max read and 1.535W max write. Operating temperature range is 0°C to 70°C with vibration resistance of 2.17G peak while running and 20G peak when powered off.

Replaces a mechanical hard drive in 2.5 inch bays

Swapping a 2.5 inch hard drive for this SSD removes moving parts, cuts noise and delivers roughly 10x faster access for the operating system and applications. The upgrade is most worthwhile when the system uses a SATA III port and the workload fits within 480GB of capacity. Larger capacities up to 1.92TB are available in the same series if more space is needed.

Questions about this item

Should I choose the 480GB A400 or one of the larger capacities up to 1.92TB?

The 480GB model provides 160TB of total bytes written and up to 500 MBps read speeds; larger capacities in the same series offer more space for applications or a full hard-drive replacement while keeping the same 2.5-inch form factor.

What does the 500 MBps sequential read figure mean once the drive is installed in my laptop?

In a real machine the SATA III link caps throughput at about 500 MBps, so you will see fast start-up, quick application loading and snappy file transfers that are roughly ten times faster than a mechanical hard drive.

The drive uses a SATA III interface — what does that cap in practice?

SATA III limits the maximum sequential read to 500 MBps and write to 450 MBps, so those are the practical ceiling speeds you will observe regardless of the 3D NAND inside.
