Compact M.2 2242 SATA drive for space-limited

This 1 TB internal SSD uses the M.2 2242 form factor and a SATA III interface to deliver solid-state storage in a 22 mm by 42 mm footprint. It is built with 3D NAND QLC memory and an SMI controller for everyday computing workloads. The drive suits ultra-thin laptops, small-form-factor desktops and embedded boards that cannot accept longer modules.

Verify slot length and interface before purchase

Confirm the host device has an M.2 socket that accepts 42 mm modules and is wired for SATA signalling rather than PCIe. Check the motherboard or laptop manual for keying type and maximum supported capacity. Ensure the BIOS or UEFI firmware recognises SATA SSDs in the M.2 slot and that no physical obstruction blocks the 3.2 mm module height.

Steady throughput under continuous workloads

Sustained sequential reads reach 570 MB/s and writes reach 500 MB/s when transferring large files over extended periods. The 3D NAND QLC architecture and SMI controller maintain consistent performance without thermal throttling within the 0 °C to 75 °C operating range. MTBF is rated at 1,000,000 hours for long-term reliability.

Questions about this item

Does the Dogfish 2242-1TB come with a mounting screw or heatsink, or do I need to buy them separately?

The drive is supplied as a bare M.2 2242 module. Most laptops and desktops include the single M2 screw; if yours is missing you will need to source one separately. No heatsink is required or included for this SATA III model.

The spec sheet lists 3D NAND QLC and a SMI controller — how do those affect which capacity I should pick?

QLC flash stores four bits per cell, so the 1TB capacity delivers the highest density in the 22mm x 42mm footprint. The SMI controller manages wear-levelling and SLC caching to keep the 570 MB/s read and 500 MB/s write figures consistent across the full capacity.

The box says "up to 570 MB/s" — what will I actually see when the drive is installed in my laptop?

In a typical SATA III 6 Gb/s slot you will see sequential reads near 570 MB/s and writes near 500 MB/s on large files. Random 4K performance and sustained write speed after the SLC cache fills will be lower, but everyday boot and application loads remain well within SATA III limits.
