T1 Drive

Thunderbolt™ Drive - CalDigit T1

The Fastest Thunderbolt Single Drive

The CalDigit T1 is a powerful single drive storage device with TWO Thunderbolt ports that supports both regular 3.5" HDD's and the much faster 2.5" SSD drives. One of the most unique functions of the T1 is that the drive is removable, something that you do not normally see on most single drive solutions. This allows for easy expansion and archiving of your important data. With the SSD drive installed, the CalDigit T1 can reach speeds of up to 470 MB/s. This type of speed in the past was only possible with much larger more expensive units that would take up all the space in your edit suite and require a lot of power to run.

T1 SSD & Hard Disk


True Flexibility

The T1 is all about flexibility. Choose the regular 3.5" HDD version for higher storage capacity - up to 4TB, or purchase the 2.5" SSD version if speed is more your thing. Even better you can daisy-chain two T1's together, the SSD version for editing your high quality video files, and the 3.5" HDD version for backing up all your content. In fact you can daisy-chain up to 6 Thunderbolt devices to one computer.
CalDigit Thunderbolt Drives Daisy Chain
The removable drive function of the T1 allows professionals to move their data from edit suite to edit suite without having to take the whole storage device with you.

SSD ready!

Why has CalDigit decided to support SSD drives? The beauty of SSD drives is that they reduce power consumption, react better to shock, and deal better with extremes in temperature, which is ideal as the T1 is a perfect storage device for moving to different locations.
