Kingston SSDNow A400 240GB Internal Solid State Drive (SA400S37/240GIN) 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 drive 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’s 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 capacities from 120GB–480GB 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.
