Lenovo ThinkPad 512GB M.2 2242 PCIe Gen4 x4 NVMe OPAL SSD (4XB1K26774) – Self-Encrypting

Compact, self-encrypting Gen4 storage for ThinkPads with M.2 2242 slots.

The Lenovo 4XB1K26774 is a 512GB M.2 2242 PCIe Gen4 x4 NVMe SSD with TCG OPAL self-encryption, designed for supported ThinkPad laptops that use the shorter 42mm M.2 slot. It delivers fast Gen4 performance and hardware encryption for business users and IT departments.

Why the Right Form Factor Matters for Thin Laptops

Many thin ThinkPad models use M.2 2242 slots instead of the common 2280 size. Standard 80mm drives will not fit, and generic 2242 drives can be hard to source with encryption and validation.

The 4XB1K26774 is built for these systems: a Lenovo-validated 2242 NVMe drive with Gen4 speed and OPAL encryption, making upgrades and replacements straightforward.

Gen4 Speed in a Small Footprint

PCIe Gen4 x4 NVMe performance keeps compact ThinkPads responsive for multitasking, conferencing and business apps.

Built-In Data Security

TCG OPAL support enables hardware encryption that integrates with BitLocker and enterprise management, protecting data if a laptop is lost.
