Internal SSD Lenovo 256GB M.2 2242 PCIe 4.0, MPN 5SS0Y86994

Lenovo 256GB M.2 2242 PCIe 4.0 internal SSD provides compact NVMe storage in the M.2 2242 form factor with a PCIe 4.0 interface. Intended for laptops, compact desktops and system upgrades, this drive is designed to serve as a primary system drive or fast secondary storage. It delivers the advantages of solid-state storage over mechanical drives, including faster boot and application load times, lower power consumption and increased resistance to physical shock.

Advantages

This internal SSD offers PCIe 4.0 bandwidth for improved sequential and random read/write throughput compared with older interfaces. The M.2 2242 form factor enables installation in space-constrained devices where a longer M.2 2280 module would not fit. As an SSD, it produces no moving parts, which reduces noise and improves reliability under mobile use. The 256GB capacity balances storage for an operating system, commonly used applications and a library of documents or media files while keeping the drive physically small and energy efficient.

Suitable for

• Replacing or upgrading a laptop system drive to improve boot and application performance
• Compact desktop and small form-factor PCs that require an M.2 2242 module
• Use as a fast secondary drive for frequently accessed files and applications

Key specifications

• Form factor: M.2 2242
• Interface: PCIe Gen4 (NVMe protocol)
• Capacity: 256GB
• Device type: Internal solid-state drive (SSD)
• Power characteristics: low power consumption typical of NVMe SSDs
• Compatibility: designed for laptops and small form-factor systems with M.2 2242 PCIe slots

How to use

Power down the host device and disconnect from power before installation. Open the device access panel according to the manufacturer’s instructions, locate the M.2 2242 slot and remove any securing screw. Carefully insert the SSD at an angle into the M.2 connector until fully seated, then press it down and secure it with the screw. Reassemble the device, power it on and enter the system BIOS or UEFI to verify detection. Initialize, partition and format the drive in the operating system, or restore an image/clone an existing system to this drive if replacing the primary disk.

Usage recommendations

For best results, use this SSD as a system or application drive to benefit from low latency and higher I/O throughput. Ensure the host system firmware supports PCIe 4.0 for maximum performance; the drive is backward compatible with PCIe 3.0 but will operate at reduced bandwidth. Keep device firmware and OS storage drivers up to date and maintain regular backups when using the drive for important data.
