Incredible speeds plus rock-solid reliability

Kingston’s A400 solid-state drive dramatically improves the responsiveness of your existing system with incredible boot, loading and transfer times compared to mechanical hard drives. Powered by a latest-gen controller for read and write speeds of up to 500MB/s and 450MB/s, this SSD is 10x faster than a traditional hard drive1  for higher performance, ultra-responsive multi-tasking and an overall faster system.

Also more reliable and durable than a hard drive, A400 is built with Flash memory. There are no moving parts, making it less likely to fail than a mechanical hard drive. It is also cooler and quieter, and its shock and vibration resistance makes it ideal for notebooks and other mobile computing devices.

A400 is available in multiple drive form factors and capacities from 120GB to 1.92TB  to give you all the space you need for applications, videos, photos and other important documents. You can also replace your hard drive or a smaller SSD with a drive big enough to hold all your files. This SSD is designed for use in desktop and notebook computer workloads and is not intended for server environments.

10x faster than a hard drive

With incredible read/write speeds, the A400 SSD will not only increase performance but can also be used to breathe new life into older systems.

Rugged

A400 is shock and vibration resistant for rugged nreliability when used in notebooks and other mobile computing devices.

Multiple capacities

A400 is available in capacities of up to 1.92TB to suit anyone’s needs.

Ideal for desktops and notebooks

A400 comes in 2.5” 7mm and M.2 form factors to fit in a wide array of systems. It is ideal for thin and light notebooks with limited space.
