The Glyph Atom EX40 4TB USB4 40Gbps Rugged Portable NVMe SSD with Removable Cover (A40EX4000) is a bus-powered external drive that reads and writes at up to 4,000 MB/s over a single USB4 Type-C port.
It is built for 8K and 12K RAW video, photo, VR, and multicam work, with a solid aluminum core and shell that carry heat away so speeds hold up during long offloads. It also works with USB 3.x and Thunderbolt 3, 4, and 5 ports.
The drive ships formatted for macOS and needs a reformat for Windows. It needs no external power supply, and a rugged removable cover adds shock protection for field use.
Glyph A40EX4000 Features
- Up to 4,000 MB/s read and write. The A40EX4000 moves large camera files quickly enough for 8K and 12K RAW offloads, multicam ingest, and editing straight from the drive. Actual speed depends on the port: a USB4 or Thunderbolt 4 port on a PC reaches the full rate.
- USB4 40Gbps Type-C connection. One USB4 (40Gb) Type-C port connects the drive to current Macs, PCs, and tablets. It is backward compatible with USB 3.0, USB 3.1, and Thunderbolt 3, 4, and 5, but slower ports lower the speed, to about 1,050 MB/s on a 10Gb USB-C port.
- 4TB of NVMe capacity. The 4TB model holds long camera-original libraries, project archives, and multiple shoot days on one drive that fits in a pocket. The Atom EX40 line also comes in 1TB, 2TB, and 8TB, so you can match capacity to the job.
- Bus-powered, no power adapter. The drive takes all its power from the USB4 port, so there is no brick or second cable to carry. That keeps a laptop, DIT cart, or edit bay simpler, but a port that cannot supply enough bus power will not run it.
- Aluminum core and fanless cooling. The solid aluminum core and outer shell pull heat away from the NVMe drive, and there is no fan to add noise or fail. This supports sustained transfer speeds during long copies and keeps the drive quiet on set or in a studio.
- MIL-STD-810F rated shell. An aluminum exoskeleton and soft composite bumper give the Atom EX40 a MIL-STD-810F rating for shock, vibration, and dust. Glyph lists no specific test values, so treat it as protection for travel and field use, not as a waterproof drive.
- Removable rugged cover. The included rugged external cover can come off when you want the slimmer drive, or stay on for extra impact protection in a camera bag or transit case. The drive measures 2.8 x 4.5 x 0.8 inches, so it still packs small.
- Formatted for macOS, Windows after reformat. The drive arrives ready for a Mac. For Windows you reformat it once, and Glyph provides a PDF guide. Plan for that step on a shared edit system, because a reformat erases the drive.
- 3-2-1 Glyph warranty. Glyph covers the drive and cables for 3 years, adds 2 years of Level-1 data recovery, and provides 1 year of advance replacement. That coverage matters when the drive holds irreplaceable footage from a shoot.
Where the A40EX4000 Fits
Video production and DIT: Offload RAW camera cards on location, then carry the footage to the edit bay on one fast, bus-powered drive.
Editing and post-production: Edit multicam and high-resolution projects directly from the drive over USB4 or Thunderbolt, without a separate power supply.
Photography and VR capture: Store large RAW photo libraries and VR footage on 4TB that survives bags, vehicles, and travel.
Live events and houses of worship: Record, archive, and move show files between control rooms and edit suites with a drive that stays quiet and cool.
