The Lenovo 4XB1D04756 is a 512GB solid state drive that installs directly into an available M.2 2280 slot and communicates with the system through a PCI Express 4.0 x4 NVMe interface. It is intended for users who want noticeably faster boot times, application launches, and file transfers without replacing the entire laptop.
Because the drive operates on the PCIe Gen4 bus, it can reach data transfer rates up to 64 Gbit/s when paired with a compatible ThinkPad. This headroom gives creators, data analysts, and software developers the bandwidth required for large media files, complex spreadsheets, and code compilation tasks. Everyday activities such as opening multiple browser tabs or resuming from sleep also feel quicker because the NVMe protocol reduces latency between the processor and non-volatile memory.
Security conscious professionals will appreciate the built-in OPAL2 self-encryption. The hardware-based approach guards sensitive information at rest and supports compliance with corporate or regulatory requirements. When combined with Lenovo’s system-level security tools, the drive helps protect intellectual property, confidential records, and client data.
Installation does not demand cables or brackets; the single-sided module slides into the existing M.2 slot and secures with one screw. Once fitted, the firmware and power management features work seamlessly with Lenovo BIOS and operating system utilities, so the upgrade feels native rather than aftermarket.
Reliability is backed by Lenovo’s adherence to international certifications such as CE, UL, and KC. These standards verify electrical safety and electromagnetic compatibility, making the drive suitable for offices, classrooms, and mobile work environments that depend on stable performance day after day.
Whether you are extending the life of a trusted ThinkPad or outfitting a new system for demanding workloads, this internal SSD provides a balanced mix of speed, capacity, and security in a design purpose-built by Lenovo for Lenovo.
