ZTC Sky Adapter M.2 NVMe to U.2

This enclosure converts an M.2 PCIe NVMe SSD into a standard 2.5" U.2 form factor. It uses a built-in SFF-8639 plug connector and an M.2 M-key receptacle to bridge the interfaces. The unit draws 3.3V power with a 4A maximum output current. Read speeds up to 3800MB/s are supported through the PCIe link.

Suits builders adding NVMe storage to U.2 bays

Users with spare 2.5" U.2 drive slots can populate them with readily available M.2 NVMe modules. The adapter includes short-circuit and thermal shutdown protection plus in-rush current suppression. It is not for users who need to connect drives using other interfaces or form factors. Systems without a U.2 backplane or cable cannot use this enclosure.

3800MB/s read speed ceiling

The single specification that determines fit is the maximum sequential read throughput of 3800MB/s. This ceiling comes from the PCIe lane configuration supported by the M.2 receptacle and SFF-8639 connector. If your workload demands higher sustained bandwidth, this adapter will bottleneck the SSD. Match the enclosure to drives and host controllers that operate within this limit.

Questions about this item

What M.2 NVMe SSD keying and connector does the enclosure accept?

The enclosure uses a built-in M.2 (NGFF) M-key receptacle connector for the SSD.

Which host-side interface must my system provide for this adapter to function?

Your system needs a U.2 (SFF-8639) port to connect the adapter's plug connector.

How do I confirm the adapter is running at full PCIe 4-lane speed after installation?

LED2 ON indicates the M.2/PCIe 4 lanes device Power OK status.
