Kingston KC600 mSATA 256GB SSD

The Kingston KC600 mSATA 256GB SSD is a SATA III internal drive built for consumer laptops and small-form-factor desktops that still use the mSATA slot. It brings 3D NAND storage to older platforms without requiring an adapter or a new motherboard.

Capacity and headroom

The 256GB capacity holds a modern operating system, core applications and a modest media library with room to spare. Sequential reads reach 550 MBps and writes reach 500 MBps, so boot and load times stay snappy; heavy video editing or large game installs will fill the drive quickly.

Build quality and connectors

The drive uses a standard mSATA edge connector and a SM2259 controller backed by 256MB of DRAM cache for steady performance. Its compact circuit board fits the mSATA slot directly, making upgrades straightforward on compatible hardware.

Questions about this item

Will this mSATA drive work in a laptop that only has a SATA II slot?

The KC600 uses the SATA III interface and is backward compatible with SATA II slots, so it will function at the older port's speed limit.

How can I confirm the drive is delivering its rated 550 MBps read and 500 MBps write speeds?

Run a benchmark tool such as CrystalDiskMark on a fresh Windows install and compare the sequential results to the 550 MBps read and 500 MBps write figures.

Does the SKC600MS/256G package include a mounting bracket or cloning software licence?

The drive ships as a bare mSATA module; any 2.5-inch adapter bracket or migration software must be obtained separately.
