Thunder3 Quad Mini
8.0TB SSD External Thunderbolt 3 Storage Solution

Thunderbolt 3 / SATA 6.0GB/s / DisplayPort / RAID 0
AKiTiO 4-Bay Storage Enclosure for 2.5" Drives
External Thunderbolt™ 3 Storage Solution for Mac and PC
This 4-bay storage enclosure is designed to house up to four 2.5-inch drives. With Software RAID, four striped SSDs can reach data transfer speeds of up to 1480 MB per second while the Thunderbolt 3 interface provides sufficient bandwidth for additional 4K video signal streams and data transfers at the same time. An ultra durable aluminum casing provides efficient heat dissipation, plus an extra large rear fan keeps your drives cool during long hours of operation.
Thunderbolt™ 3
Thunderbolt 3 brings Thunderbolt to USB-C at speeds up to 40 Gbps, creating one compact port that does it all - delivering the fastest, most versatile connection to any dock, display, or data device. For the first time, one computer port connects to Thunderbolt devices, every display, and billions of USB devices. A single cable now provides four times the data and twice the video bandwidth of any other cable, while also supplying power to bus-powered devices.

The AKiTiO Thunder3 Quad Mini has two Thunderbolt 3 ports. The second port operates the same as a Thunderbolt 3 computer port by supporting Thunderbolt 3 (up to 5 daisy chained), USB 3.1 (10 Gbps), and DisplayPort devices.
The dedicated DisplayPort connector makes it easy to connect an additional monitor to extend your workspace and it will free up the second Thunderbolt 3 port for other Thunderbolt 3 (up to 5 daisy chained), USB 3.1 (10 Gbps), and DisplayPort devices.
Power delivery over USB-C
The AKiTiO Thunder3 Quad Mini supports power delivery (PD) over USB-C, providing 15W of power to laptops like the MacBook Pro (late 2016) that support charging from a 5V/3A power source. This allows you to work with the external drive without the battery levels of your laptop dropping even though the laptop is not plugged into any other power source.
Removeable trays
Designed to house up to four 2.5-inch drives, the tray based system allows for easy installation and replacement of the hard disk drives (HDDs) and solid state drives (SSDs).

Standard Mechanism

    Release Candidate (RC) firmware set

    There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

    Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at:

    It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

  • The maximum data transfer rate for the disks inside the Thunder3 Quad Mini is product is about 1375 MB/s. To reach these kind of speeds, four striped SSDs (Apple Software RAID 0) are required.
  • Not all laptops can be charged from a 15W (5V/3A) source. To fully recharge your laptop, please plug in the laptop's power adapter to your computer.
  • This product was designed for use with the fan on and passed engineering tests with the fan on. We have added a fan switch that can turn off the fan when a low-noise environment is needed. However, the device should only be used for short periods of time with the fan in the OFF position as prolonged use may cause the device to overheat and this may cause damage to the system, cause issues to data integrity, reduce system reliability and/or shorten the lifespan of the electrical components. For best results, we recommend that the device not be used continuously for more than 30 minutes with the fan in the OFF position.
  • The DisplayPort does not support DP++. When using a DisplayPort to HDMI adapter, make sure to use an active adapter.
  • This enclosure is NOT compatible with drives that require 12V (e.g. Seagate Constellation or WD VelociRaptor).
  • This product has components or design elements that are patented or patent pending.
