Dogfish Technology 2242-240GB 3D NAND TLC SATA internal SSD

Compact M.2 2242 SATA SSD for Laptops and Desktops

This Dogfish drive uses the 2242 form factor and a SATA III 6 Gb/s interface to deliver 240 GB of storage in a module that measures 22 mm by 42 mm. It is built with 3D NAND TLC flash and an SMI controller, making it suited for consumer laptops and small-form-factor desktops that need a lightweight, low-power upgrade from a mechanical hard disk.

Simple Plug-in Install with Common Pitfalls

The drive slides into any M.2 slot wired for SATA and is secured with a single screw; no cables or brackets are required. Most issues arise when the slot is keyed only for PCIe or when the system BIOS disables the SATA controller, so verify the slot type and enable SATA in firmware before assuming the hardware is faulty.

Steady SATA Speeds Under Continuous Workloads

Sequential throughput settles at up to 550 MB/s read and 450 MB/s write once the SLC cache is filled, and the built-in ECC, wear-levelling and bad-block management keep error rates low during long write sessions. The controller supports DevSleep, TRIM and NCQ, so the drive maintains consistent latency and low power draw even when the operating temperature approaches 75 °C.
