SSD disk Lenovo 256GB M.2 2242 PCIe Gen3 x4 5SS1J39526

The Lenovo 256GB M.2 2242 PCIe Gen3 x4 SSD is a compact solid-state drive designed for space-constrained systems such as ultrabooks and small form-factor desktops. It uses the M.2 2242 form factor and a PCIe Gen3 x4 interface to deliver faster sequential and random read/write performance than SATA-based drives. With 256GB of usable capacity, the drive is intended to provide a balance between storage space and responsiveness for operating systems, applications and game installations.

Advantages

This SSD offers lower latency and higher throughput compared with traditional hard drives and SATA SSDs due to its PCIe Gen3 x4 connection. The M.2 2242 compact dimensions allow installation in thin laptops and mini-PCs where longer M.2 modules would not fit. Solid-state architecture reduces mechanical failure risk and improves shock resistance, while the 256GB capacity provides a practical boot and application volume for everyday use and performance-sensitive tasks.

Suitable for

• Upgrading ultrabooks and thin-and-light laptops with limited drive bay space
• Improving boot and application load times on compact desktop systems and mini-PCs
• Installing a primary OS drive for general productivity, media playback and casual gaming
• Replacing older M.2 drives or SATA drives to gain better responsiveness and reliability

Key specifications

• Form factor: M.2 2242
• Interface: PCIe Gen3 x4
• Capacity: 256 GB usable storage
• Drive type: Solid State Drive (NVMe over PCIe)
• Physical size: 22 mm width × 42 mm length

How to use

Power off the system and disconnect from mains power before installation. Locate the M.2 slot on the motherboard or laptop, remove any securing screw or bracket, and insert the module into the slot at a shallow angle until fully seated. Press the module down and secure it with the mounting screw. Reassemble the device, power it on and enter the firmware/UEFI to confirm the drive is detected. Initialize, partition and format the drive within the operating system, or restore an OS image if replacing a boot drive. Use manufacturer-recommended firmware updates and cloning tools when applicable.

Usage recommendations

For reliable operation, ensure your system supports M.2 2242 modules and PCIe Gen3 x4 lanes. Maintain regular backups and enable TRIM support in the operating system. Avoid exposing the drive to extreme temperatures and handle the module by its edges to prevent electrostatic damage.
