Ultra-fast 40Gbps NVMe enclosure

The TerraMaster D1 SSD Plus is a single-bay M.2 2280 NVMe enclosure built around a 40Gbps USB Type-C interface. It targets video editors, photographers and professionals who need portable, high-throughput storage for 4K or 8K workflows. The aluminium chassis doubles as a heatsink for silent, fanless operation.

Tool-free installation and common pitfalls

The drive slides into the M.2 slot and secures without tools, while the enclosure connects over USB Type-C to Windows, Mac, Linux, Android or iOS devices. Write caching must be enabled in Windows to reach the quoted throughput, and the host port must support Thunderbolt 5, Thunderbolt 4, Thunderbolt 3 or USB 4 to unlock the top speed tier.

Interface ceiling and capacity ceiling

The 40Gbps link tops out at 3853MB/s read and 3707MB/s write when paired with a 990 PRO 4TB drive over Thunderbolt 5; lesser host protocols will reduce those figures. Only one M.2 2280 NVMe SSD up to 8TB is supported, so users needing multiple drives or larger single volumes must look elsewhere.

Questions about this item

How do I confirm the enclosure is hitting the 3853MB/s read and 3707MB/s write speeds after setup?

Connect via Thunderbolt 5 with a 990 PRO 4TB NVMe SSD installed, then run a benchmark tool such as CrystalDiskMark to verify read and write results match the published figures.

What comes in the box and which M.2 NVMe 2280 SSD must I supply myself?

The package includes the aluminum D1 SSD Plus enclosure, a USB Type-C cable, and quick-start documentation; you must purchase a compatible M.2 2280 NVMe SSD separately.

Which capacity of M.2 2280 NVMe SSD should I choose for this enclosure?

Any M.2 2280 NVMe SSD up to 8TB is supported; select the capacity that fits your 4K editing, backup, or boot-drive workload.
