Thunderbolt 3 PCIe M.2 enclosure

This aluminium and steel chassis adds a full-size PCIe x16 slot and an M.2 PCIe x4 adapter to any computer with a Thunderbolt 3 port. An included 65 W power adapter and a 92 mm sleeve-bearing fan keep the installed card cool during sustained workloads. The unit measures 11.00 x 5.60 x 3.20 inches and weighs 3.60 lbs.

Who this suits and who should look elsewhere

Creative professionals and developers who need to run PCIe add-in cards or high-speed M.2 SSDs on a laptop or compact desktop will benefit from the 40 Gbps Thunderbolt 3 link. Builders who require multiple drive bays, internal mounting inside a case, or a host connection faster than 40 Gbps should consider other solutions.

Deciding specification: 40 Gbps Thunderbolt 3

The single figure that determines compatibility is the 40 Gbps Thunderbolt 3 interface, which sets the maximum data rate for any installed PCIe x4 M.2 SSD or expansion card. If the host port delivers less bandwidth, performance will be limited accordingly.

Questions about this item

How loud is the 92 mm fan when the enclosure runs continuously?

The 92 mm sleeve-bearing fan spins inside an aluminium and steel chassis; fan speed is not adjustable, so audible airflow will be present during sustained loads.

Which host connection does the unit require to operate?

A Thunderbolt 3 port on the host computer is mandatory; the included Thunderbolt 3 cable links the enclosure to that port.

Can the PCIe x16 slot accept a legacy PCIe x1 or x4 card?

The chassis provides a PCIe x16 female slot that is electrically wired for x4; cards that fit mechanically will be limited to x4 bandwidth.
