Overview

The Lenovo 4XB0K59917 is an OEM storage bay adapter designed to mount an M.2 SSD inside compatible ThinkPad laptops. Rather than a generic third-party bracket, this is Lenovo's own tray — precision-molded to match the internal bay dimensions of the ThinkPad L560, P50, P70, and Yoga 460. It bridges the physical gap between the compact M.2 form factor and the laptop's standard storage bay, providing secure retention and proper connector alignment so the drive seats correctly on the first attempt.

This adapter is relevant for users looking to expand storage in their ThinkPad workstations — particularly the P50 and P70, which support multiple internal drives and benefit from adding a fast M.2 SSD alongside an existing 2.5-inch disk. Installation is purely mechanical: no drivers, no firmware updates, no BIOS configuration beyond standard drive detection. It's a niche part that solves a specific problem for a specific set of machines, and for those machines, the OEM tray is the safest path to a clean installation without risking connector damage from ill-fitting aftermarket alternatives.

Pros & Cons

👍 Pros

  • OEM Lenovo part guarantees exact dimensional fit and connector alignment with supported ThinkPad bays.
  • Enables M.2 SSD installation in a standard storage bay, unlocking faster storage without sacrificing an existing drive slot.
  • Simple mechanical adapter with no drivers or firmware required — install the tray and the system recognizes the drive.
  • Compatible across four ThinkPad product lines, covering both mobile workstation and ultrabook form factors.

👎 Cons

  • Strictly limited to four ThinkPad sub-models — incompatible with any other Lenovo laptops or newer ThinkPad generations.
  • Functions only as a physical mounting tray with no electronics, so drive protocol support depends entirely on the host machine's bay controller.
  • Lenovo does not clearly document which M.2 key types and lengths the tray accommodates, requiring manual verification.
  • Availability can be inconsistent as an older OEM part, with pricing that sometimes exceeds the cost of the M.2 drive itself.

Frequently Asked Questions

It is compatible with the ThinkPad L560 (20F1, 20F2), P50 (20EN, 20EQ), P70 (20ER, 20ES), and ThinkPad Yoga 460 (20EL, 20EM). Check your machine type against these specific sub-model numbers before purchasing, as other ThinkPad generations use different tray dimensions.
The adapter is a physical tray that seats an M.2 form factor drive into the laptop's storage bay. Whether it passes SATA or NVMe signals depends on your ThinkPad's bay controller — consult Lenovo's hardware maintenance manual for your model to confirm which M.2 protocols the bay supports.
Yes, if your compatible ThinkPad has an open M.2 bay slot. The P50 and P70, for example, support multiple storage devices. This tray lets you populate an additional bay with an M.2 SSD without replacing your primary drive.
It is an OEM Lenovo storage bay adapter. Confirm the included hardware against your model's service documentation, as some ThinkPad bays use screws that ship with the laptop chassis rather than the tray accessory.
