Consistent Performance
Because the Fusion Thunderbolt 3 NVMe SSD's enclosure is milled with extremely tight tolerances, it maximizes heat transfer from the specific M.2 SSD installed inside. This allows a fanless design, but, more importantly, enables the drive to operate for sustained periods, most importantly during large file transfers, without thermal-throttling of the SSD’s performance, a problem encountered by competing products.

Speed Dial Icon

Amazing Transfer Speeds & Performance
The Fusion Thunderbolt 3 NVMe SSD incorporates a PCIe Gen 3 flash controller that enables the device to outperform USB 3.0 flash drives by more than 500%, and is capable of transferring files at rates up to 2600 MB/s.⁽¹⁾

Fusion Thunderbolt 3 PCIe Flash Drive In Palm of Hand Icon

Designed with Latest SSD Technology
Sonnet designed the Fusion Thunderbolt 3 NVMe SSD around a Gen 3 M.2 PCIe SSD module, the fastest standard SSD type now available. It connects directly to any computer with a Thunderbolt 3 port, or at the end of a Thunderbolt 3 device daisy chain, via a captive 0.5-meter Thunderbolt 3 (40Gbps) cable.

Replaceable Captive Cable
Through the use of a captive cable, the Fusion Thunderbolt 3 NVMe SSD's Thunderbolt cable remains firmly connected to it at all times. Should the cable ever break, it can easily be replaced with an approved replacement cable available from Sonnet or a Sonnet-authorized reseller.

Technical Notes

Most computers equipped with Thunderbolt 3 connect four PCIe lanes (x4 PCIe Gen 3) to Thunderbolt 3. Some computers connect only two PCIe lanes (x2 PCIe Gen 3) to some or all ports, which will result in performance of the Fusion Thunderbolt 3 NVMe SSD being reduced to about 1400 MB/s when connected to those ports.
