Kingston A400 SSD

$ 67.78 Price excluding tax

The Kingston A400 SATA3 2.5″ SSD is a reliable solid-state storage solution designed to improve system responsiveness, startup times, application loading, and file transfers. Available in a compact 2.5-inch, 7mm-height design, it is ideal for upgrading compatible desktop PCs, notebooks, and other systems using a standard SATA drive interface.

Description

The Kingston A400 SSD combines solid-state performance with a practical 2.5-inch form factor, making it an effective upgrade for systems still using traditional hard disk drives.

Using a SATA Rev. 3.0 (6Gb/s) interface, the A400 provides fast data transfer and is backward compatible with SATA Rev. 2.0 systems. For the 480GB version, Kingston specifies sequential performance of up to 500MB/s read and 450MB/s write, helping improve boot times, application loading, file transfers, and overall system responsiveness.

The 7mm-thick 2.5-inch design allows the drive to fit a wide range of desktop and notebook systems. Kingston specifically positions the A400 for both desktops and notebooks, including thin systems where drive height is an important consideration.

Because the A400 has no moving mechanical components, it is designed to provide greater resistance to shock and vibration than conventional hard drives. This makes it suitable for everyday computing environments as well as mobile systems.
