The Glyph Atom EX20 4TB NVMe SSD is a high-performance storage solution engineered for professional creators, videographers, and editors who require reliable, sustained throughput for demanding 4K video workflows and massive media transfers. It excels by providing lightning-fast speeds of up to 2,100 MB/s housed in a rugged, heat-dissipating aluminum chassis that prevents thermal throttling during intense use. While it offers industry-leading durability and data protection features, potential users should note that they must have a USB 3.2 Gen 2x2 compatible port to achieve the maximum advertised speeds.

Yes, it is fully compatible with Thunderbolt 3, 4, and 5 ports, though it will operate at the maximum speed of the USB protocol supported by the connection.
No, the Atom EX20 is bus-powered, meaning it draws all necessary power from the device to which it is connected.
It includes three years of hardware coverage, two years of Level-1 data recovery services, and one year of advanced replacement.
While it is built to MIL-Standard 810F for shock and dust, it is not rated as waterproof; keep it dry to prevent damage.
Yes, but you may need to reformat the drive to ExFAT if you intend to move files seamlessly between both operating systems.
Check the physical USB-C connection at both ends and try a different high-speed USB-C port on your computer.
Ensure you are using a port compatible with USB 3.2 Gen 2x2; using a standard USB 3.0 or 3.1 port will limit transfer speeds.
The Atom EX20 is pre-formatted for compatibility with most production systems. To set up, simply connect the included USB-C cable to your computer's high-speed port. For optimal performance, always ensure you are plugging the device into a dedicated USB 3.2 Gen 2x2 port if available. While the drive is backward compatible with Thunderbolt and older USB ports, speeds will be capped by the interface limits of those older ports. To care for your drive, avoid placing it in extreme high-temperature environments and ensure the connector remains free of debris. Always use the 'eject' command on your operating system before physically disconnecting the drive to maintain file system integrity.
