mSATA form factor for legacy upgrades

This 500 GB internal SSD uses the mSATA form factor and a SATA III 6 Gb/s interface. It fits desktops and laptops that still rely on the mSATA slot rather than M.2. The 3D NAND TLC memory and SMI controller provide a direct replacement for older mechanical drives in compatible systems.

Sustained throughput with DevSleep support

Sequential reads reach up to 570 MB/s and writes up to 500 MB/s under continuous load. The drive supports DevSleep ultra-low power state, SMART monitoring, TRIM and NCQ commands to maintain consistent performance during extended workloads. Built-in ECC and bad-block management further protect data integrity over long sessions.

Lightweight board with industrial temperature range

The bare PCB measures 30 mm by 50 mm and weighs 7 g, so it adds no mechanical strain to the motherboard slot. Operating temperature spans 0 °C to 75 °C and storage temperature reaches -45 °C to 85 °C at up to 95 % humidity. MTBF is rated at 1,000,000 hours for long-term reliability in daily use.

Questions about this item

How much heat and noise does the Dogfish mSATA-500GB produce during all-day operation?

The drive has no moving parts and runs within a 0 °C to 75 °C operating range, so it adds minimal heat and is completely silent compared with mechanical drives.

What must my laptop or desktop already have for this mSATA-500GB to work?

A free mSATA slot that accepts a 30 mm by 50.9 mm card and supports the SATA III 6 Gb/s interface.

Will the Dogfish mSATA-500GB run correctly in an older system that only supports SATA II 3 Gb/s?

Yes, the SATA III interface is backward compatible, so the drive will function at the host's maximum SATA II speed without any configuration changes.
