EN-Labs M-Key NVMe M.2 to SFF-8643 Adapter Card

SKU CH-JS0X-7W195

Converts M.2 M-Key NVMe SSDs to SFF-8643 for 2.5" U.2 drives with PCIe 4.0 and 64GT/s speed

  • Converts M.2 M-Key NVMe SSD to SFF-8643 interface
  • Connects 2.5" U.2 NVMe SSD via SFF-8639 to SFF-8643 cable (cable not included)
  • PCIe 4.0 compatible, backwards compatible with PCIe 3.0
  • Data transfer speed up to 64 GT/s
  • Supports M.2 2260 and 2280 slot installation

M-Key NVMe to SFF-8643 Adapter

This adapter card converts an M.2 M-Key NVMe slot connection to a SFF-8643 Mini SAS interface. It enables a 2.5" U.2 NVMe SSD to connect via an SFF-8639 to SFF-8643 cable, which is not included. The card supports PCIe 4.0 specification with backwards compatibility to PCIe 3.0. No drivers are required for current operating systems.

Suited for U.2 NVMe SSD integration

Builders adding a U.2 NVMe drive such as the Intel 750 series to an M.2 2260 or 2280 slot will find this card fits the purpose. It is strictly for U.2 NVMe SSDs and does not support Mini SAS array protocols. Buyers needing to connect SAS hard drives or RAID arrays should look at a different solution.

PCIe 4.0 support up to 64GT/s

The single specification that decides compatibility is the PCIe 4.0 interface with a data transfer rate up to 64GT/s. This determines whether the host platform can utilise the full bandwidth of the attached U.2 NVMe SSD.

Questions about this item

What M.2 slot lengths does the adapter card support?

The card supports M.2 2260 and 2280 form factors for M-Key NVMe SSDs.

How is the adapter connected to a U.2 SSD, and what step is often missed?

A separate SFF-8639 to SFF-8643 Mini SAS cable is required to link the card's SFF-8643 port to the 2.5" U.2 SSD; the cable is not included.

What ongoing compatibility should be checked when upgrading the U.2 SSD later?

Only U.2 NVMe SSDs are supported; the adapter does not work with MiniSAS array protocol drives.
