PCIe 5.0 EDSFF to U.2 Adapter

The LetLinkSo LLS-CD-1ED1UT-01 is a PCIe 5.0 EDSFF to U.2 SFF-8639 adapter card that converts enterprise NVMe SSDs with a 28-pin EDSFF connector to a standard U.2 interface. It supports E1.S, E1.L, E3.S and E3.L form factors using a genuine LOTES 28-pin slot and an Amphenol SFF-8639 connector for enterprise-grade signal integrity. The adapter operates at up to 32GT/s and is fully backwards compatible with PCIe 4.0 and 3.0.

For enterprise storage upgrades

This adapter suits system integrators and server administrators upgrading rackmount storage systems with next-generation EDSFF NVMe drives in existing U.2 backplanes. It is OS-independent and requires no additional drivers for Windows Server, Linux, VMware or Proxmox environments. It is not for builders who need a second card for dual-drive configurations or for users attempting to connect drives without a 28-pin EDSFF interface.

28-pin EDSFF slot

The single specification that decides fit is the 28-pin EDSFF connector on the device side, which accepts E1.S, E1.L, E3.S and E3.L enterprise SSDs. The host side provides a U.2 SFF-8639 male connector for direct backplane insertion. Correct installation requires aligning the arrows on both sides of the drive to prevent damage during insertion.
