Adapter for Asus Zenbook UX31 and UX21

This card lets an M.2 NGFF B+M key SATA SSD replace the original 18-pin proprietary drive found in Asus Zenbook UX31 and UX21 models. The PCB matches the factory dimensions of 94 mm by 24 mm for a direct fit. It is built with copper conductors and a SATA connector for the host interface. The unit is supplied new and ready for installation.

Suitable for owners of listed Zenbooks needing

This upgrade suits owners of Asus Zenbook UX31 or UX21 laptops who want to swap a failed or undersized 18-pin SSD for a standard M.2 NGFF SATA drive. It does not work with M-key PCIe SSDs, so buyers needing that interface must choose a different solution. Laptops outside the UX31 and UX21 series are not supported.

Key constraint: B+M key SATA only

The adapter electrically supports NGFF B+M key SATA SSDs in four lengths: 2230, 2242, 2260 and 2280. It will not function with M-key PCIe drives. Verify that the replacement SSD uses the B+M key SATA interface before purchase.

Questions about this item

What comes in the package and do I need to buy an M.2 SSD separately?

The package contains the 18-pin upgrade card only; a compatible M.2 NGFF B+M Key SATA SSD in 2230, 2242, 2260 or 2280 size must be purchased separately.

Which M.2 drive sizes and models are supported by this adapter?

The card accepts four NGFF form factors — 2230, 2242, 2260 and 2280 — and is designed to replace Sandisk SD5SE2/SDSA5JK 64 GB, 128 GB, 256 GB and ADATA XM11 128 GB, 256 GB drives.

What does the 18-pin interface mean for real-world use in a Zenbook UX31 or UX21?

It connects a standard M.2 NGFF B+M Key SATA SSD to the laptop's proprietary 18-pin slot, matching the original 94 mm × 24 mm PCB so the drive fits without modification.
