CalDigit T4 Thunderbolt 3 RAID HDD

This product had been made End Of Life.



T4 Features

The CalDigit T4 Thunderbolt 3 supersedes the now discontinued Thunderbolt 2 version and with it adds extra functionality.

Not only does it provide Multiple RAID modes which can be combined, the Thunderbolt 3 interface also charges the connected laptop and the T4 also provides the ability to connect a 4K monitor using the added display port.

T4 Capacities

The Caldigit T4 ranges from 4TB up to a massive 32TB and is also available with SSD’s (Call sales for SSD option).

T4 RAID Options

The T4 supports:

  • RAID 0 (Performance) – up to 750MB/s.
  • RAID 5 (Performance combined with redundancy) – up to 550MB/s.
  • RAID 1 (4 automatic backups)

Not only that but the 4 disks mean that you can mix RAID levels. e.g. You could configure two drives to RAID 0 and the other two to RAID 1. That is just a fraction of the possibilities. Get ready to design the RAID you want!

CalDigit T4 Industrious Design

The T4’s die-cast aluminum chassis offers a level of durability unmatched by inferior metals. The aluminum design also helps with heat dissipation keeping the T4 cool at all times.
