Lenovo ThinkPad 512GB M.2 2242 PCIe Internal SSD

The Lenovo 4XB0T83221 is a 512 GB solid state drive that uses the PCIe NVMe interface and fits the M.2 2242 slot found in many ThinkPad laptops. Created as an internal upgrade, it provides additional capacity without changing the laptop’s footprint or weight.

By delivering up to 2000 MBps read speed and 860 MBps write speed, the drive shortens boot times, accelerates application launches, and moves large files with ease. A single PCIe lane handles the data flow, keeping power use efficient while still offering strong bandwidth for everyday workloads.

Its compact 42 mm length and weight of about 5 grams allow simple installation in systems where space and portability are priorities. Business travelers, students, and remote workers can enjoy fast storage while maintaining a light laptop.

Lenovo certifies the drive for ThinkPad E490, E490s, and E590 models, so firmware and thermal characteristics align with those systems. It slips into the standard M.2 bay, making the swap or upgrade a task most users can complete with basic tools.

The drive meets international compliance standards and comes with a 1 year limited warranty, giving peace of mind to anyone who relies on consistent performance throughout the day.
