Product Features
Technical Overview
This external SSD uses a PCI Express NVMe internal architecture to achieve its high throughput. The dual-mode host interface supports both Thunderbolt 3 at 40 Gbps and USB 3.2 Gen 2 Type-C at 10 Gbps, ensuring compatibility with modern PCs and Macs. The drive is formatted for out-of-the-box use with macOS 10.13+ and Windows 10+ systems.
Performance is sustained by an integrated thermal management system that draws heat away from the NVMe controller and NAND flash. This design prevents thermal throttling during large file transfers, such as moving 50 GB of data in 30 seconds or less.
Relevant factors for this section include Storage Capacity, Platform Supported, Maximum Read Transfer Rate, Maximum Write Transfer Rate. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
