01HARD DRIVES
Silent speed in an aluminum shell
A compact block of aluminum, the ACASIS TBU405Pro sits quietly on your desk, its brushed surface catching the light as it manages high-speed data flows. It is the kind of hardware that disappears into a workflow, offering power without noise.
Designed for creators and professionals who need reliable external storage, this enclosure connects via USB-C and supports drives up to 8TB. It keeps performance stable during heavy workloads, ensuring your files move as fast as you do.


02MATERIALS
Precision-machined aluminum construction
The enclosure’s body is crafted from durable aluminum alloy, a material chosen for its ability to dissipate heat efficiently. This structural choice provides long-term reliability while maintaining a sleek, professional aesthetic. The metal casing acts as a passive heatsink, working in tandem with the internal fan to keep temperatures stable even under sustained load.

04COOLING
Active airflow with manual control
Inside the chassis, a built-in silent fan circulates air to maintain optimal SSD temperatures. A manual control allows users to adjust the fan speed, balancing acoustic quietness against maximum cooling capacity. This flexibility is particularly useful when the drive is handling intensive read-write cycles, preventing thermal throttling without adding unnecessary background noise to a studio or office environment.
05COMPATIBILITY
Flexible support for various drive sizes
The enclosure accepts M.2 NVMe PCIe solid-state drives in four standard lengths: 2230, 2242, 2260, and 2280. With a maximum capacity of 8TB, it accommodates both compact and high-volume storage needs. Installation is tool-free, allowing for quick swaps and upgrades without screwdrivers or technical expertise, making it accessible for frequent reconfiguration.
