Form factor and audience

The Dogfish Technology M.2 2242 240GB SATA internal SSD is a compact drive built for consumer laptops and desktops with a 22 by 42 millimetre slot. It uses TLC NAND and a SMI controller to deliver solid-state storage without moving parts.

Sustained load behaviour

Sequential reads reach up to 550 MBps while writes reach up to 500 MBps under continuous operation. Built-in ECC, wear-levelling and bad-block management keep data integrity stable, and DevSleep plus trim support help maintain consistent throughput over long sessions.

SATA interface limits

The SATA III link caps transfer rates at 6 Gbps, so the drive cannot exceed the quoted 550 MBps read and 500 MBps write ceilings. Operating temperature ranges from 0 to 75 Celsius, and the drive is rated for 1000000 hours MTBF within those thermal limits.

Questions about this item

How much noise and heat does the Dogfish M.2 2242 240GB SATA SSD produce during all-day operation?

The drive has no moving components so it generates no mechanical noise. With a maximum operating temperature of 75 °C and support for DevSleep ultra-low-power state, heat output stays low even under continuous use.

What interface slot must my laptop or desktop already have for this Dogfish 2242 240GB drive to work?

The system needs an M.2 2242 key slot wired for SATA III. The drive is 22 mm wide and 42 mm long, so the slot must accept that exact form factor.

Will this Dogfish SATA M.2 2242 SSD work alongside an older 2.5-inch SATA drive in the same machine?

Yes. Both drives use the SATA interface, so they can coexist as long as the motherboard provides a separate M.2 2242 SATA slot and a 2.5-inch SATA bay or adapter.
