The Micron 2400 2TB is a solid-state drive in the compact M.2 2230 format. It uses the NVMe protocol over a PCIe 4.0 x4 connection, and Micron rates it at up to 4500 MB/s reads and 4000 MB/s writes. The 2230 size is the point: it fits devices that have room only for a short drive.
What M.2 2230 means
M.2 drives are named by their width and length in millimetres. A 2230 drive is 22 mm wide and 30 mm long, a lot shorter than the common 2280 size (80 mm). Many laptops and desktops use 2280, which is why this size matters: a 2230 drive suits the smaller slots in handheld PCs and compact laptops, and it can also go in a slot that accepts several lengths.
The listing names the Steam Deck, the ROG Ally, and any laptop or desktop with an M.2 2230 slot as compatible. Fitting depends on the slot's length, the mounting screw position and the interface, so check the device's manual before buying.
PCIe 4.0 and NVMe in plain terms
NVMe is a protocol designed for flash storage that talks to the processor over PCIe lanes, which is far quicker than the older SATA connection. PCIe 4.0 x4 means four lanes at the fourth-generation speed. The speeds Micron quotes, up to 4500 MB/s read and 4000 MB/s write, are best-case sequential figures. Everyday use, such as loading games or opening apps, usually depends on other factors as well, so you won't see those figures in every task.
If a device only supports PCIe 3.0, a PCIe 4.0 drive generally works, but at the slower speed of the older standard.
2TB of capacity
A 2TB capacity matters most for portable devices, where internal space is limited. Large game libraries, video projects and downloaded media take up a lot of space, and the 2TB size gives plenty of room. Formatted capacity shows as slightly less than 2TB on most systems, because of how decimal and binary units are counted.
Cloning and installing
When swapping a drive, you generally need to move your operating system and files. Some people clone the old drive, others reinstall. A small M.2 drive typically screws or clips onto a single mounting point. The listing doesn't describe a heatsink, and compact devices usually have limited space, so follow the device maker's instructions and any heat guidance.
A note on the listing
The listing's dimension and weight fields contain figures that clearly don't describe an SSD of this size, so they're best ignored. The type is a bare drive, so check what's in the box with the seller or the manufacturer's information.
Who it suits
It suits owners of handheld gaming PCs and small laptops who want to expand internal storage, and anyone whose device takes only 2230 drives.
What to check before you buy
- Slot size: confirm that your device takes M.2 2230, not only 2280.
- Interface: check that the slot supports NVMe (not SATA-only M.2) and PCIe.
- Mounting: make sure the screw or retainer suits a 2230 drive.
- Warranty: look up the manufacturer's warranty terms and source.
- Data: back up your files before swapping drives.
- Software: check any device instructions for opening it and warranty effects.
