how to install StarTech.com Thunderbolt 3 to M.2 adapter

• Power down your computer and unplug it if required by your setup, then open the enclosure access area to reveal the M.2 slot.
• Insert your M.2 SSD into the slot with the notch aligned properly, then secure the drive using the provided screw or retention hardware.
• Close the enclosure, connect the Thunderbolt 3 cable from the enclosure to a Thunderbolt 3 port on your computer, and connect the external power supply if your drive requires it for sustained performance.
• Power on your computer and allow the operating system to recognize the new external storage device. If needed, initialize or format the drive in your OS’s disk management utility (Disk Utility on macOS or Disk Management on Windows).
• Configure your file system to suit your workflow (for example APFS or HFS+ on macOS, NTFS or exFAT on Windows, or exFAT for cross-platform use), then start transferring large files or editing directly from the external PCIe storage.

Frequently asked questions

• Q: What kind of drives can I use with this enclosure?

  A: It supports M.2 SSDs (primarily NVMe PCIe drives) and, where applicable to the enclosure model, SATA M.2 drives. Always verify the specific compatibility for your drive model and form factor before purchase.

• Q: Do I need an external power supply?

  A: For sustained NVMe performance, an external power supply is typically required. Some lower-power configurations or SATA-based drives may operate with minimal power, but check your drive’s power needs and enclosure guidelines.

• Q: Will this work with both Windows and macOS?

  A: Yes. The Thunderbolt 3 interface provides cross-platform compatibility with modern Windows and macOS systems that include Thunderbolt 3 support. No specialized drivers are usually required for standard operation.

• Q: Can I use this as a boot drive?

  A: While it is technically possible in some configurations, external booting behavior depends on the host system's firmware and OS support. For critical workflows, verify boot drive requirements and test in a controlled environment before relying on it as a boot device.

• Q: How do I maximize performance?

  A: Use an NVMe M.2 SSD with a high endurance rating and ensure you’re connected via a Thunderbolt 3 port. Use a compatible power supply if required, keep the enclosure well-ventilated, and format the drive with a file system suited to your workload and OS.
