mSATA form factor and SATA III interface

This internal solid-state drive uses the mSATA form factor with a SATA III 6 Gb/s interface. It is designed for consumer desktops and laptops that have an mSATA slot. The drive measures 30 mm by 50.9 mm and weighs 7 g. It provides 128 GB of storage capacity using 3D NAND flash memory.

Replaces a mechanical hard drive in an mSATA slot

The SSD upgrades a system that currently relies on a spinning hard drive in an mSATA slot. Sequential read speeds reach up to 500 MB/s and writes up to 400 MB/s, reducing boot and application load times. The jump is worth it when the host platform supports SATA III and the existing drive is a bottleneck. Built-in ECC, bad block management and TRIM support help maintain data integrity.

Sustained operation within 0 °C to 75 °C

The controller manages thermal output during extended workloads without moving parts. Operating temperature range is 0 °C to 75 °C, while storage temperature spans -45 °C to 85 °C. DevSleep ultra low power state reduces energy draw during idle periods. MTBF is rated at 1,000,000 hours for long-term reliability under continuous use.

Questions about this item

Will the 30 mm by 50.9 mm mSATA board fit my laptop slot?

The drive measures 30 mm by 50.9 mm and 1 mm thick, matching the standard mSATA form factor used in many laptops and desktops.

How do I install the mSATA SSD and what step is often missed?

Insert the card at an angle into the mSATA slot, press down, and secure it with the retention screw; the step often missed is fastening that screw so the drive cannot work loose.

What maintenance will the 128 GB 3D NAND drive need over its 1 000 000 hour MTBF life?

No scheduled maintenance is required; keep the system firmware and OS TRIM support active, monitor health via S.M.A.R.T., and ensure airflow so the drive stays within its 0 °C to 75 °C operating range.
