    Multiple capacities

    KC600 is available in a range of full capacities from 256GB to 2TB.2

    1. 256GB — up to 550/500MB/s. 512GB–2048GB — up to 550/520MB/s. Based on “out-of-box performance” using a SATA Rev. 3.0 motherboard. Speed may vary due to host hardware, software, and usage. IOMETER Random 4k Random Read/Write is based on 8GB partition.

    2. Some of the listed capacity on a Flash storage device is used for formatting and other functions and thus is not available for data storage. As such, the actual available capacity for data storage is less than what is listed on the products.

    The Kingston KC600 SKC600/256G is a 256GB 2.5-inch SATA III internal SSD with sequential speeds up to 550 MB/s read and 500 MB/s write, suited to upgrading a compatible SATA laptop or desktop for everyday computing.

    Recommended For

    • Owners of older laptops or desktops with a 2.5-inch SATA drive bay who want to replace a hard drive with a solid-state drive for quicker booting, app loading, and file access.
    • People upgrading a SATA-based computer who want a responsive everyday system drive for an operating system and frequently used applications, rather than a high-capacity storage drive.
    • Users with sensitive data who need a 2.5-inch SATA SSD with hardware-based encryption support, provided their system and security software support the relevant encryption features.
    • Users who regularly move large files on a SATA system and value consistent drive performance during extended writes; a review found the KC600 maintained write speed through a 450GB file transfer on the tested 1TB model.

    Real-World Use Scenarios

    • Replacing a mechanical hard drive in an older laptop or desktop: users can move the operating system and everyday apps to the KC600 and typically get quicker startup and app-loading than with the old hard drive, provided the computer has a compatible 2.5-inch SATA bay.
    • Moving an existing Windows setup to a replacement drive: users can clone the old drive with compatible migration software, then boot from the KC600, avoiding a fresh OS and app installation if the cloning process and system setup work correctly.
    • Setting up a basic everyday computer for web browsing, documents, and a few commonly used apps: the 256GB capacity can serve as the main drive for a lean setup, but users with large game libraries, media collections, or work files may need additional storage.
    • Adding a drive to a desktop that has an unused 2.5-inch SATA connection: users can install the KC600 as a separate location for frequently used apps or files, while keeping their existing drive for other data; actual compatibility depends on the system’s available connections and mounting space.
    • Using a compatible system that supports hardware-based drive encryption: users can enable the KC600’s supported encryption features to protect stored data, but this requires compatible system software and configuration.
