Lenovo 512GB M.2 2242 PCIe Gen3 x4 NVMe SSD (5SS0V26438)

For systems constrained by the compact M.2 2242 slot, this Lenovo 512GB drive delivers full PCIe Gen3 x4 bandwidth without the bulk of a 2280 card. It pairs Samsung PM991a-class hardware with OEM firmware validation, ensuring drop-in compatibility with Lenovo ThinkPad, IdeaPad, and ThinkCentre models that demand a short-card NVMe solution.

Highlights

• 512GB capacity with 3D TLC NAND for balanced endurance and cost
• M.2 2242 form factor fits ultra-thin laptops and small-form-factor desktops
• PCIe Gen3 x4 interface with NVMe 1.3 protocol for low latency
• Sequential reads up to 3100 MB/s and writes up to 1800 MB/s
• Hardware AES 256-bit encryption supports self-encrypting drive features
• 300 TBW endurance and 1.5 million hours MTBF for long service life

In daily use

Boot times shrink to seconds and large file transfers complete noticeably faster than SATA SSDs. The 2242 length keeps the drive entirely within the M.2 slot, leaving room for Wi-Fi cards or other components in cramped chassis. Power draw stays under 5W active and below 0.05W idle, helping preserve battery runtime in mobile workstations.
