Lenovo 1TB M.2 PCIe 3.0 x4 Internal SSD

The Lenovo 4XB0N10301 is a 1TB solid state drive that fits the M.2 slot in many Lenovo laptops and desktops, including a wide range of ThinkPad models. It connects through a PCIe 3.0 x4 interface, letting the system move data along four dedicated lanes so files, applications, and the operating system respond more quickly.

With read speeds up to 300 MB/s and write speeds up to 1700 MB/s, the drive shortens boot times and keeps large projects—such as raw photos, 4K footage, or complex spreadsheets—moving at a pace that feels smooth and predictable. NVMe support reduces overhead compared with older SATA drives, which helps the processor reach data with fewer delays.

Lenovo builds and tests this model for ThinkPad compatibility, so installation is straightforward and firmware glitches are unlikely. The card uses TLC flash memory to balance capacity, endurance, and cost, and its single-sided design means it slides into most M.2 slots without clearance issues.

Security is handled at the hardware level through OPAL support. When paired with suitable management software, you can enable encryption that protects sensitive work documents or client files without slowing everyday tasks.

This drive is a practical upgrade for mobile creatives who need fast media transfers, business travelers who want quicker resume times, and students who prefer an overall snappier system. Installation requires only a small screwdriver and a few minutes, making it an accessible boost for anyone comfortable with basic hardware upgrades.
