120 GB mSATA SSD for compact systems

The Kingston SMS200S3/120G is a 120 GB internal solid-state drive built on an mSATA form factor using MLC NAND. It targets notebooks, ultrabooks and desktops that have a native mSATA slot and need a direct replacement for a mechanical hard drive.

SATA 3.0 interface caps throughput at 6 Gb/s

Sequential reads reach up to 550 MBps and writes reach 520 MBps, which is the practical ceiling of the SATA 3.0 link. The drive draws 1.2 W during typical reads and 1.8 W during writes, while idle consumption sits at 0.4 W.

Replaces 2.5 inch hard drives one-eighth the size

The caseless PCB design measures roughly one-eighth of a 2.5 inch HDD, enabling installation in space-constrained chassis. It supports Intel SRT caching and TRIM, so the upgrade is most worthwhile when moving from a spinning disk to solid-state for boot, application launch and multitasking responsiveness.

Questions about this item

Will this mSATA drive fit in my laptop's 2.5-inch drive bay?

No, this drive uses the mSATA form factor which is one-eighth the size of a 2.5-inch drive and requires a dedicated mSATA slot on the motherboard.

Can I use this drive as a cache for my existing hard drive?

Yes, the drive supports Intel Smart Response Technology which allows it to function as a high-speed cache alongside a larger mechanical hard drive.

What operating system features are needed to maintain long-term performance?

The drive supports the TRIM command which maintains maximum performance on compatible operating systems that implement this feature.
