ZTC M.2 NGFF to USB 3.0 Adapter

The ZTC-EN004-G adapter connects an M.2 NGFF solid-state drive to a standard USB 3.0 port. It serves users who want to clone an existing drive, move files between computers, or repurpose an internal SSD as portable external storage. The enclosure works with both Windows and macOS systems without requiring additional drivers. Its tool-free design allows quick drive installation for immediate data access.

Sustained transfer performance

The adapter supports UASP protocol and SuperSpeed operation rated at 6Gb/s with real-world throughput up to 520MB/s. These figures reflect steady-state movement of large files rather than brief burst speeds. The USB 1.1 interface specification listed in the technical data appears inconsistent with the advertised SuperSpeed capability; actual sustained rates will depend on the host controller and the specific NGFF drive installed. Users transferring multi-gigabyte datasets should see consistent performance near the quoted ceiling.

Thermals noise and power draw

The compact aluminium shell acts as a passive heatsink for the enclosed M.2 drive during normal operation. No active cooling fan is present, so the device runs silently in typical office or home environments. Power is drawn entirely from the host USB port, eliminating the need for an external supply. Surface temperature rises moderately during extended write sessions but remains within safe handling limits for a bus-powered enclosure.

Questions about this item

Does the USB 1.1 connection generate noticeable heat when the adapter runs all day?

The USB 1.1 interface limits transfer speed to a level that keeps power draw low, so the enclosure stays cool during continuous use.

What must I already own to use this adapter with a M.2 NGFF SSD?

You need a M.2 NGFF SSD and a host device with a standard USB port; the adapter itself requires no extra cables or power supply.

Will this adapter work alongside an older USB 1.1 hub I still use?

Yes, the USB 1.1 interface is backward-compatible, so it will function on legacy hubs and ports without driver issues.
