Glyph Technologies Blackbox PRO Overview

With an electro galvanized, cold rolled, coil steel, and aluminum enclosure, the 20TB Blackbox PRO USB 3.2 Gen 2 External Hard Drive from Glyph Technologies is designed to protect your important data from the elements. Inside this rugged housing is a 20TB hard drive featuring USB-C 3.2 Gen 2 connectivity, making it simple to connect directly to Mac computers, as it comes preformatted HFS+. The drive is also compatible with Windows based computers; all that is needed is a quick reformat of the drive. Regardless of the operating system, the Blackbox PRO hard drive spins at 7200 rpm, supports a transfer rate of up to 260 MB/s to transfer even large files quickly and efficiently, and is also compatible with Thunderbolt 3 ports.

Included with the Blackbox PRO is a USB-C to USB-C cable, a USB-C to USB-A cable, a removable external cover, and an external power adapter.

Enterprise Class
With a capacity of 20TB, this enterprise class drive features data transfer speeds of up to 260 MB/s and is built for demanding workflows and mission critical projects.
Universal Compatibility
Featuring a 10 Gb/s USB-C 3.2 Gen 2 port, the Blackbox PRO is backward compatible with USB 3.2 Gen 1. It may also be used with Thunderbolt 3, but will not achieve Thunderbolt speeds.
Time Machine Ready
The Blackbox PRO is formatted for macOS and is Time Machine compatible right out of the box. It may be easily reformatted for Windows.
Stay Cool Under Pressure
Don't be afraid to put the Blackbox PRO to work. The rugged aluminum shell acts as a heatsink, keeping the internal hard drive at its optimal temperature to deliver higher sustained speeds.
Comprehensive Warranty
Every Glyph drive comes with their 3-2-1 warranty, which is three years of full hardware coverage, including the cables, two years of Level-1 data recovery, and one year of advanced replacement.

Glyph Technologies Blackbox PRO Reviews

VERY SOLID

By Amilcar
Rated 5 out of 5
Date: 2026-06-11

I've bought their products since they started. I had one of their 1st gen drives die on me more than ten years ago and they took great care of me. Since then I've never had a problem. The 12tb will serve my current film just fine.

Solid build, quick transfers
