The D4-320 hard drive enclosure (a DAS, NOT a NAS) utilizes the USB 3.2 Gen2 protocol, achieving high-speed data transmission of up to 10Gbps. When equipped with four hard drives, the actual read/write speed can reach up to 1,016 MB/s (combined read/write with four SATA III HDDs of 8TB each). With just one SSD installed, the read speed effortlessly reaches 510 MB/s (SATA III 1TB SSD).
The D1 SSD Pro 80Gbps NVMe enclosure delivers up to 7061MB/s read speed (tested with Samsung 990 PRO 4TB on Mac M4 Pro via AJA), enabling smooth, real-time multi-track 12K editing with no lag—an ideal external nvme enclosure for professional workflows.
The D4-320 USB storage supports 4 individual disks (NO RAID function), and is plug-and-play, eliminating the need for drivers. It is highly compatible with MAC, Windows, and Linux operating systems. The USB Type-C interface supports various computer interfaces, including USB 3.0, USB 3.1, USB 3.2, Thunderbolt 3, and Thunderbolt 4.
The D1 SSD Pro m.2 nvme enclosure is built with a 270g CNC-machined aluminum shell, and features pre-installed heatsinks and a 38-fin, 2mm dual-fin design that maximizes cooling surface area, keeping SSDs at peak speed during intensive 8K editing without thermal throttling.
The D1 SSD Pro m.2 external enclosure features smart LED Indicator which shows connection speed at a glance: White for Thunderbolt/USB4 high-speed mode, Orange for standard USB - no software required.
