Green PCB adapter card with gold connectors and 50cm cable

Vszerda

Vszerda Mainboard SSD Slimline SAS PCIe Adapter NGFF M-Key NVME to SFF-8654 U.2 SFF-8639 Cable

SKU CH-MEPK-R5FCR

Connects an M-Key NVMe SSD to an SFF-8654 Slimline SAS interface using a 50cm cable and supports PCIe 3.0 and 4.0

  • Connects NVMe drives via SFF-8654 Slimline SAS
  • Includes 50 cm cable for flexible routing
  • Supports PCIe 3.0 and 4.0 speeds
  • Works with Windows 10 or later
  • Designed for NGFF M-Key and U.2 SSDs

Connectivity adapter

The Vszerda adapter connects an NGFF M-Key NVMe drive to a motherboard through an SFF-8654 Slimline SAS interface and a U.2 SFF-8639 cable. The package includes one card and one 50cm cable. It is built for server or workstation builders who need to add high-speed NVMe storage without a native M.2 slot. It does not support SAS or SATA disks.

Sustained throughput

The card supports PCIe 3.0 and PCIe 4.0 at four lanes, so sustained transfer rates follow the drive and host controller limits rather than the adapter itself. Under continuous workloads the passive design relies on system airflow to keep the drive within its thermal envelope. Windows 10 or later is required for driver support.

Upgrade path

This adapter replaces a direct M.2 installation when the board lacks an M-Key slot or when the drive must sit in a U.2 bay. The jump is worthwhile when an enterprise NVMe drive such as a 750 series SSD is already on hand and the platform offers a free PCIe x4 link. Buyers who need SAS or SATA connectivity should look elsewhere.

Questions about this item

How much power does the adapter draw when the NVMe drive runs continuously?

The adapter is a passive board with no active components, so it adds no measurable power draw beyond the NVMe drive itself.

What motherboard slot must be free to install the NGFF M-Key card?

An M.2 M-Key slot wired for PCIe 3.0 x4 or 4.0 x4 is required; the card will not function in a SATA-only M.2 slot.

Will a legacy SAS or SATA drive work if I plug it into the SFF-8654 or SFF-8639 connector?

No, the adapter only passes PCIe NVMe signals and explicitly does not support SAS or SATA protocols.
