Kingston A400.

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 the newest generation controller for read and write speeds up to 500MB/s and 450MB/s.* This SSD is 10X faster than a traditional hard drive* for better performance, ultra-responsive multi-tasking and an overall faster system.

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

The A400 is available in multiple capacities from 120 GB – 960 GB** 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 this drive which is big enough to hold all your files.


The SSD is designed for use in desktop and notebook computer workloads and is not intended for server environments.

  • Fast start-up, loading and file transfers
