Dogfish 1 TB mSATA SSD

The Dogfish mSATA-1TB is an internal solid-state drive built for consumer laptops and desktops that accept the mSATA form factor. It uses 3D NAND flash and a SMI controller on a SATA III 6 Gb/s interface to deliver up to 550 MBps sequential read and 450 MBps sequential write. The drive measures 30 mm by 50 mm with a 1 mm profile and weighs 0.05 g. It is rated for 1,000,000 hours MTBF and operates from 0 °C to 75 °C.

Thermals noise and power in normal use

With no moving parts the drive produces no audible noise and adds minimal heat to the system during typical workloads. The controller supports DevSleep for an ultra low power state when the host is idle, and the 3D NAND structure helps reduce cell-to-cell interference for steady reliability. Operating humidity tolerance spans 0 % to 95 % non-condensing.

Sustained load behaviour

Under continuous read and write activity the drive maintains its rated sequential speeds of up to 550 MBps read and 450 MBps write within the 0 °C to 75 °C operating window. Built-in ECC, wear levelling and bad block management work together to preserve data integrity during prolonged transfers. The drive also supports SMART, TRIM and NCQ commands to optimise performance over time.

Questions about this item

How do I install the Dogfish mSATA 1TB SSD into a laptop slot, and what alignment step is often missed?

Insert the 30mm by 50.9mm board at a slight angle into the mSATA connector, press down until the retention clips click on both sides, then secure with the single mounting screw; skipping the screw leaves the drive loose and can break the SATA III link.

What maintenance or replacement will the 1TB 3D NAND drive need over its service life?

No scheduled maintenance is required; the SMI controller handles wear levelling, bad-block management and ECC automatically, and the 1,000,000-hour MTBF rating indicates the drive itself is the only replaceable part if it eventually fails.

At what point does the 550 MB/s sequential read speed stop scaling under sustained heavy workloads?

The SATA III 6 Gb/s interface caps sustained throughput at roughly 550 MB/s read and 450 MB/s write, so the bus limit is reached before the 3D NAND or controller throttles under continuous load.
