Glyph Blackbox Plus 1 TB portable SSD

The Glyph Blackbox Plus is a 2.5 inch bus-powered portable SSD with a 1 TB capacity. It connects through a USB-C port that supports USB 3.1 Gen 2 and Thunderbolt 3. Maximum sequential read and write speeds reach up to 450 MBps. The enclosure is finished in black.

Suits creatives needing fast Thunderbolt 3 storage

Editors and photographers who work on Thunderbolt 3 laptops will gain quick bus-powered access to 1 TB of solid-state capacity. The 450 MBps ceiling limits users who need sustained multi-gigabyte throughput for high-bitrate video or large RAID-style workloads. Buyers without Thunderbolt 3 ports will not reach the stated performance.

Thunderbolt 3 interface decides compatibility

This drive requires a host port that implements Thunderbolt 3 to deliver the advertised 450 MBps speeds. On a plain USB 3.1 Gen 2 connection the drive still functions but performance may fall below the rated maximum. Verify that your computer provides a Thunderbolt 3 controller before purchase.

Questions about this item

Should I pick the 1TB version of this Glyph Blackbox Plus?

The 1TB capacity gives you roughly one thousand gigabytes for projects and media libraries, and it is the only capacity this model offers.

What do the 450 MBps read and write speeds mean when I plug the drive in?

You can expect up to 450 MBps for both sequential reads and writes, so large video files or backups move at that rate under typical workloads.

How does the USB 3.1 interface and Thunderbolt 3 support affect real-world transfer limits?

The USB 3.1 Gen 2 connection caps throughput at its rated bandwidth, and Thunderbolt 3 provides an alternative high-speed path when your host supports it.
