4TB portable NVMe SSD

The Glyph Atom EV provides 4TB of NVMe storage in a compact enclosure that connects through a USB 3.2 Gen2 Type-C port. It is aimed at creators and professionals who need fast external capacity for media libraries, backups or active project files.

Replaces slower USB 3.0 drives

Moving from a USB 3.0 external drive to this 10Gbps interface can cut large-file transfer times roughly in half when the host port supports the full standard. The jump is worth it for workflows that move multi-gigabyte assets daily and where the host system has a compatible Type-C or Thunderbolt 3 connection.

Limited by 10Gbps USB ceiling

Sequential reads top out at 1000 MBps and writes at 1050 MBps, so the drive cannot saturate faster Thunderbolt 3 or USB4 links. Sustained throughput will also depend on the host controller, cable quality and thermal conditions inside the fan-less enclosure.

Questions about this item

Will the drive fit in a standard 2.5-inch drive bay?

The drive measures 12.7 mm high, 44.45 mm wide and 111.76 mm deep, so it is narrower than a typical 2.5-inch bay and would need an adapter or bracket.

What cables are included for connecting to different ports?

The box contains a USB-C to USB-C cable and a USB-C to USB-A cable, letting you plug into USB 3.2 Gen2, USB 3.0 or Thunderbolt 3 ports.

What real-world transfer speed can I expect?

The drive is rated for up to 1000 MB/s sequential read and up to 1050 MB/s NVMe performance, though actual speeds depend on the host port and file sizes.
