Key Specifications to Verify:

• NVMe Protocol Support: Confirm compatibility with your target NVMe SSD (PCIe Gen 3/4, specific keying – M-key is standard). Incompatibility renders the enclosure useless.

Transfer Speed (Read/Write): Advertised speeds are maximums*. Real-world performance depends on SSD, cable quality, and host system. Look for independent testing data if available.

• Interface: USB 3.2 Gen 2x2 (20Gbps) is optimal for PCIe Gen 4 SSDs. USB 3.1 Gen 2 (10Gbps) is sufficient for Gen 3. USB-C is the preferred connector.
• Enclosure Material & Thermal Management: Aluminum enclosures with heat sinks are crucial for sustained performance and preventing thermal throttling. Plastic enclosures are generally unsuitable for high-performance drives.
• UASP Support: Essential for maximizing transfer speeds. Confirm support in the product description.
• Form Factor Support: 2280 is the most common NVMe SSD form factor. Verify compatibility if you use other sizes (2242, 2260, 22110).
