Lenovo 256GB M.2 2242 PCIe Gen3 x4 NVMe SSD (5SS1D71684)

When a laptop's built-in storage runs out, most users settle for external drives that dangle from USB ports and slow down workflows. The Lenovo 256GB M.2 2242 PCIe Gen3 x4 NVMe SSD (5SS1D71684) takes a different route: it replaces the internal drive entirely, unlocking the full potential of the system's PCIe lanes. Engineered for select ThinkPad, IdeaPad, and Yoga models, this drive delivers read speeds up to 2000 MB/s, making boot times nearly instant and large file transfers a matter of seconds.

Highlights

• 256 GB capacity with 3D TLC NAND for reliable everyday storage
• M.2 2242 form factor fits ultra-thin laptops without adding bulk
• PCIe Gen3 x4 NVMe 1.3 interface maximizes bandwidth for demanding tasks
• Sequential read up to 2000 MB/s and write up to 1200 MB/s
• Endurance of 100 TBW and MTBF of 1.5 million hours for long-term confidence

In daily use

From cold boot to desktop in under ten seconds, this SSD changes how a laptop feels. Applications launch without the spinning-wheel delay, and multitasking remains fluid even with dozens of browser tabs and a video call running. The 2242 size means it slips into the same slot as the original drive, preserving the laptop's slim profile. With power consumption of just 3.5 W active and 0.05 W idle, battery life stays intact during extended work sessions.
