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–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. * Based on “out-of-box performance” using a SATA Rev. 3.0 motherboard. Speed may vary due to host hardware, software and usage. **Some of the listed capacity on a Flash storage device is used for formatting and other functions and is thus not available for data storage. As such, the actual available capacity for data storage is less than what is listed on the products.
