Read & write over 6000 MB/s
That performance level is only achievable over Thunderbolt / USB4 with a fast NVMe SSD. In real use, you can expect speeds in the 3,000–6,000 MB/s range depending on SSD model, system, and workload.

Dual‑chip design: JHL9480 + RTL9210

• JHL9480: Intel Thunderbolt controller (Thunderbolt 4/USB4 class), handling the high‑speed host connection.

• RTL9210: Realtek USB–NVMe bridge controller, widely used and stable for NVMe enclosures.
  Together, they allow compatibility with both Thunderbolt and standard USB hosts.

Host compatibility

• Thunderbolt 5/4/3 ports on laptops/desktops (ideal for max performance).

• USB 4/3.2/3.1/3.0 ports (works as a high‑speed USB NVMe enclosure; performance will be limited by the specific USB standard).

SSD support

• Form factors: M.2 2230/2242/2260/2280 NVMe.

• Capacity: up to 8TB.

• Protocol: NVMe only (not for SATA M.2).

• It even claims support for PCIe Gen5 NVMe SSDs like Samsung’s high‑end models; note that:

  • The drive will work, but actual speed is still limited by Thunderbolt/USB bandwidth.

  • Gen5 mainly gives you overhead and better future‑proofing rather than full Gen5 speed in this enclosure.

Cooling and build

• Adjustable cooling fan to manage heat from fast NVMe drives (important at 6000+ MB/s).

• Tool‑free design means you can open the enclosure and install/replace the SSD without screws, making upgrades quick and easy.

Typical use cases

• 4K/6K/8K video editing off external SSD.

• Large project files (software dev, VMs, Docker images).

• Fast OS or game libraries on external storage for Thunderbolt laptops.

• Professional backup where speed really matters.
