KingSpec 128 GB 1.8-inch SATA SSD

This KingSpec ACJC2M128S18 is a 128 GB internal solid-state drive built in the 1.8-inch form factor with a SATA III interface. It uses a JMicron JMF608 controller and MLC NAND flash to deliver sequential reads up to 495 MB/s and writes up to 191 MB/s. The drive is suited to any Windows or Mac system that provides a standard SATA connection.

Suits older laptops and embedded systems needing

The 1.8-inch size and SATA III interface make this drive a direct fit for legacy notebooks, industrial PCs or compact appliances that only accept this physical format. Buyers whose hardware requires a 2.5-inch drive, an M.2 module or a higher capacity than 128 GB will need a different part.

1.8-inch form factor decides compatibility

The single specification that determines whether this SSD works is its 1.8-inch physical size combined with the SATA III connector. If the target device does not have a matching 1.8-inch SATA bay, the drive cannot be installed regardless of its performance figures.

Questions about this item

What do I need in my system for this 1.8-inch SATA III drive to work?

Any Windows or Mac system with a SATA interface will accept the 128GB ACJC2M128S18; the JMicron JMF608 controller and MLC NAND Flash handle the rest.

Can I keep using an older SATA II controller with this SSD?

The drive runs on SATA III at up to 495MB/sec read and 191MB/sec write, and will negotiate down to SATA II speeds if the host controller only supports that standard.

How can I verify the ACJC2M128S18 is healthy after installation?

Enable SMART monitoring in your OS or BIOS; the drive reports temperature (0°C–70°C range), media wear and other health attributes through the standard SMART interface.
