    The Kingston A400 SA400S37/240G is a 240GB 2.5-inch SATA III internal SSD for users upgrading a compatible desktop or notebook from a hard drive, with sequential read speeds up to 500 MB/s and write speeds up to 350 MB/s.

    Recommended For

    • Owners of an older laptop or desktop with a 2.5-inch SATA bay who want to replace a mechanical boot drive and make startup and app loading feel more responsive.
    • People refreshing a thin or older notebook that needs a 7 mm, 2.5-inch SATA replacement drive and mainly runs an operating system and everyday applications.
    • Budget-conscious users who need a basic SATA drive for a lightweight operating-system installation, documents, and a small set of apps rather than demanding storage workloads.
    • Notebook owners replacing a mechanical drive who value a light, shock- and vibration-resistant storage device for ordinary mobile computing.
