  • Dynamic power management and TRIM support maintain consistent performance over time

Capacity and form factor

This BIWIN mSATA drive provides 256GB of storage in a 50.8mm by 29.85mm module. It uses MLC NAND flash for a balance of endurance and cost. The SATA III interface fits older notebooks and industrial boards that still rely on the mSATA slot.

Interface headroom

The SATA III link runs at 6Gb/s, so sequential throughput tops out near the bus limit. Random read and write performance is adequate for OS drives and light workloads but will saturate well before modern PCIe storage. Heavy sustained writes will hit the controller and NAND ceiling before the interface does.

Temperature envelope

Rated operation spans 0°C to 70°C, with storage survival down to -40°C and up to 85°C. The thin 4.85mm profile offers little thermal mass, so airflow matters in fanless or sealed chassis. Dynamic power management and SMART monitoring help manage heat during idle periods.

Questions about this item

Will this mSATA drive fit in a standard full-size mSATA slot?

Yes, it measures 50.8 mm long, 29.85 mm wide and 4.85 mm thick, matching the standard full-size mSATA form factor.

Is the SATA 6 Gb/s interface backward compatible with older SATA 3 Gb/s ports?

Yes, the SATA III interface negotiates down to 3 Gb/s on older ports, so the drive works in both generations of SATA host controllers.

What NAND type is used and how does it affect endurance?

The drive uses MLC NAND, which typically provides higher program/erase cycle endurance than TLC, helping sustain performance over heavy write workloads.
