  • Connects U.2 NVMe SSDs to SFF-8643 Mini SAS HD ports
  • 50 cm length fits compact server and workstation builds
  • PCIe 3.0 x4 electrical interface supports up to 4 GBps throughput
  • Compatible with SSD 750 M.2 and Hyper Kit storage controllers
  • Cable-only design — adapter and card sold separately

Connecting U.2 NVMe SSDs to Mini SAS HD ports

This 50 cm cable links a U.2 SFF-8639 NVMe SSD to a mainboard or controller with an SFF-8643 Mini SAS HD connector. It carries PCIe 3.0 x4 signals at up to 4 GBps for high-speed storage. The cable is sold alone; no adapter or card is included.

Suited for builders adding U.2 drives to Mini SAS

Ideal for users with a compatible mainboard, Ultra M.2 card or Hyper Kit storage controller who need a direct NVMe link. Not suited for systems lacking an SFF-8643 Mini SAS HD port or for installations requiring a longer reach than 50 cm.

SFF-8639 to SFF-8643 connector pairing decides fit

The cable bridges a U.2 SFF-8639 device plug to an SFF-8643 Mini SAS HD host receptacle. Verify your host has the SFF-8643 port and your drive uses the SFF-8639 interface before purchase.

Questions about this item

What PCIe standard does the SFF-8639 to SFF-8643 cable support, and what bandwidth does that provide?

The cable is rated for PCIe 3.0 x4, giving a practical throughput of 4 GBps when used with a compatible U.2 NVMe SSD and Mini SAS HD connector.

What clearance and connector spacing does the 50 cm length require inside the chassis?

At 50 cm the cable reaches from a motherboard SFF-8643 port to a 2.5-inch U.2 drive bay; allow room for the SFF-8639 plug width and the Mini SAS HD latch clearance.

How is the cable connected, and which orientation mistake is common?

Plug the SFF-8643 end into the motherboard or controller Mini SAS HD port and the SFF-8639 end into the U.2 SSD; the frequent error is inserting the SFF-8639 connector upside-down, which prevents the latch from engaging.
