The Lenvanta ST569 converts an M.2 M-Key slot into a single-port U.2 (SFF-8643) connection, letting you run an enterprise U.2 NVMe SSD from a consumer motherboard’s M.2 slot. It’s PCI Express Revision 3.1 compliant and NVM Express 1.2a compliant, with transfer speeds up to 4GB/s (32Gb/s) per port.

No drivers are needed — the adapter is transparent to the operating system, so any OS with native NVMe support (Windows 8 through 11, Windows Server 2012 R2+, and most current Linux distributions) will see the drive without extra setup.

How It Works

Insert the adapter into an available M.2 M-Key slot on your motherboard.
Connect the cable (adapter + cable option) from the adapter’s SFF-8643 port to your U.2 SSD’s SFF-8639 port.
Boot up: the drive is detected automatically once your BIOS/UEFI and OS recognise the NVMe device. No drivers required.

Compatible U.2 NVMe Drives

Any 2.5″ U.2 NVMe SSD using the SFF-8639 connector is compatible, including:

Intel: DC P3500, P3600, P3700, P4500, P4510, P4600
Samsung: PM963, PM983, PM9A3
Micron: 9200 ECO/MAX/PRO, 9300 MAX/PRO
WD/HGST: Ultrastar SN200, SN640

Important — Before You Buy

NVMe PCIe only — does not support SATA or SAS drives or M.2 SATA slots. Your motherboard’s M.2 slot must be PCIe M-Key.
U.2 SSD not included — this listing is for the adapter (and cable, on the relevant options) only.
Cable required for U.2 connection — the adapter-only option needs a compatible SFF-8643 to SFF-8639 cable (sold separately, or pick the adapter + cable option).
BIOS/UEFI compatibility — confirm your motherboard supports NVMe boot/detection via M.2 if you plan to boot from the U.2 drive.
