What is M.2 2260?
M.2 2260 is an M.2 storage form factor measuring 22 mm wide and 60 mm long, primarily used for compact SSDs and expansion devices. The number "2260" identifies the module's physical dimensions rather than its speed or storage capacity. It exists to provide a space-efficient storage solution for thin laptops, mini PCs, embedded systems, and industrial devices.
Key Takeaways
- M.2 2260 measures 22 mm × 60 mm.
- It is a physical size specification, not a performance rating.
- Can support both SATA and PCIe NVMe interfaces, depending on the device.
- Common in compact computers and embedded applications.
- Requires a motherboard or device with a 2260 mounting point.
Why Does M.2 2260 Exist?
As computers became thinner and more compact, manufacturers needed storage devices smaller than traditional 2.5-inch drives. The M.2 standard introduced multiple module lengths, including 2260, allowing hardware designers to balance available space, cooling, and storage requirements.
The 60 mm length provides more room for NAND flash chips than shorter modules like M.2 2230 while remaining smaller than the common M.2 2280 format.
How Does M.2 2260 Work?
M.2 2260 SSDs connect directly to an M.2 slot on the motherboard.
The module communicates using either:
- PCIe NVMe for high-speed data transfer
- SATA for compatibility with older platforms
The SSD is inserted into the M.2 connector at an angle and secured with a mounting screw positioned at the 60 mm mark.
Key Characteristics
- Width: 22 mm
- Length: 60 mm
- Form factor: M.2
- Supported interfaces: SATA or PCIe NVMe
- Supported key types: Usually M-Key or B+M Key, depending on the SSD
- Mounting: Single screw at the 60 mm position
Compatibility
M.2 2260 SSDs work only if the host device supports:
- An M.2 slot
- The correct module length (2260)
- The required interface (SATA or PCIe NVMe)
- The appropriate keying (M-Key, B-Key, or B+M Key)
Many desktop motherboards designed for M.2 2280 also support shorter modules like 2260 through multiple mounting holes.
Advantages
- Smaller than standard M.2 2280 drives
- Suitable for space-constrained devices
- Lower cable clutter than 2.5-inch SSDs
- Supports modern NVMe technology when compatible
- Easy installation and replacement
Limitations
- Less common than M.2 2280
- Fewer product choices in the consumer market
- May accommodate fewer NAND chips than longer modules
- Not compatible with systems lacking 2260 mounting support
M.2 2260 vs Other M.2 Sizes
| Form Factor | Dimensions | Common Use Cases |
|---|---|---|
| M.2 2230 | 22 × 30 mm | Ultra-compact laptops, handheld gaming devices |
| M.2 2260 | 22 × 60 mm | Compact laptops, embedded systems, industrial PCs |
| M.2 2280 | 22 × 80 mm | Most desktop and laptop NVMe SSDs |
| M.2 22110 | 22 × 110 mm | Enterprise SSDs, servers, workstations |
Common Misconceptions
- M.2 2260 does not indicate SSD speed. Performance depends on whether the drive uses SATA or PCIe NVMe.
- All M.2 SSDs are not interchangeable. Physical length, interface, and key type must all match the system.
- Longer SSDs are not automatically faster. Module length mainly affects physical capacity and component placement.
Real-World Examples
M.2 2260 SSDs are commonly found in:
