The speed ratings shown for NVMe SSDs are usually based on internal testing using direct connections inside a computer (like an M.2 slot). When you use the SSD in an external enclosure—especially one using USB 3.2 Gen 2 (10Gbps)—you’ll likely see lower speeds, and that’s expected. This is because external enclosures use a different connection type that has its speed limits.

To make sure you’re getting the best results:

1. Ensure your NVMe drive is properly formatted (APFS or ExFAT).
2. Plug the enclosure into a USB-C port on your computer that supports 10Gbps speeds or more (look for USB 3.2 Gen 2 or a Thunderbolt/USB4 port).

You can also try:

• Testing with a different SSD.
• Reformatting the drive to a different supported format.
• Connecting the enclosure to another computer with a USB 3.2 Gen 2 or Thunderbolt port.

Finally, please make sure your system is up to date. We also recommend removing other USB-C devices and restarting your computer to refresh connections.
