Compact mSATA drive for thin devices

The Kingston SSDNow mS200 uses the mSATA form factor and a SATA 6Gb/s interface to fit notebooks, tablets and Ultrabooks where a 2.5 inch drive cannot. It offers 240GB of NAND flash storage with no moving parts, making it suited to system builders and enthusiasts who need a small, shock resistant boot or cache drive.

Caseless PCB design for easy mounting

The board-only construction measures 1.000 in height and plugs directly into an mSATA slot without brackets or cables. Withstanding 2.17G peak vibration while operating and 20G peak when powered off, the drive stays reliable in mobile chassis that see frequent movement or thermal cycling.

Low power draw and wide temperature range

Idle consumption sits at .4W, helping battery life in portable systems. The controller is rated for 0°C to 70°C operation and survives storage from -40°C to 85°C. Sequential reads reach 540MBps and writes 530MBps, while 4KB random performance hits 21000 read IOPS and 41000 write IOPS, all backed by a 1000000 hour MTBF.

Questions about this item

What real-world throughput does the SATA 6Gb/s interface cap this drive at?

The SATA 6Gb/s interface limits the SMS200S3/240G to its rated sustained sequential speeds of up to 540MBps read and 530MBps write in practice.

What slot and clearance does the mSATA form factor need to fit?

It requires a standard mSATA slot on the motherboard; the caseless PCB-only design is eight times smaller than a 2.5-inch drive and just 1.000 mm high.

How is the mS200 installed, and which step do builders often miss?

Insert the drive into the mSATA slot at an angle, press down, and secure it with the mounting screw; the step often missed is fastening that screw so the PCB cannot lift under vibration.
