Acasis 40Gbps Tool-free M.2 NVMe SSD Enclosure Compatible with Thunderbolt 4/3

TBU405 VS TBU405Pro

TBU405 is base version (Tool-free Installation), while TBU405Pro (Tool-free Installation + Built-in Silent Fan) is an upgraded version of TBU405. The main difference is that TBU405Pro is additionally equipped with a built-in silent cooling fan.

According to tests conducted by the ACASIS laboratory, after continuous use for 1 hour, the internal SSD temperature of TBU405Pro remained as low as 35°C, providing robust protection for your valuable data.

40Gbps Ultra-Fast Transfer Rate

In tests conducted at the ACASIS laboratory using a 2TB Samsung 980 Pro SSD and a MacBook Pro, the ACASIS 40Gbps NVMe SSD enclosure read/write speeds reaches up to 2805MB/s / 2734MB/s.

Note: Don't buy SSDs with heatsinks. Choose SSD capacity based on your needs.

Dual-Chip Design for Dual Stability

Unlike other enclosures that use the ASMedia® AMS2464 chip, ACASIS adopts a dual-chip design, ensuring backward compatibility with Thunderbolt 5/4/3 and USB4/3.2/3.1/3.0/2.0. The JHL7440 chip and the REALTEK® RTL9210B chip are perfectly combined, ensuring stable and smooth data transfer. The JHL7440 chip serves as the main controller, supporting up to 40Gbps ultra-fast transfer rates.

Multiple Heat Dissipation

The built-in cooling fan, aluminum alloy shell with corrugated surface and thermal pad work together for quadruple heat dissipation effect, protecting the SSD from overheating while reducing power consumption and ensure great performance all along.

Tool-Free Installation, Plug and Play

No more worries about losing screws. The ACASIS storage enclosure features a tool-free design, supporting M-key and B+M key any size PCIe NVMe SSDs. No driver installation or external power supply is required, truly achieving plug-and-play functionality.

*TBU405 supports up to 8TB of SSD.
The above data are the results of speed tests conducted by Acasis Labs.  The speed obtained may vary depending on the SSD used, file formats, and operating systems.
