Ranked #6 in Best Portable SSDs

ACASIS USB4 40Gbps NVMe Enclosure

3.8

$79

The ACASIS TBU405 Air delivers strong real-world performance for users needing fast external NVMe storage at a budget-friendly price point. My Tech Grid reviewer Everett Ashford praised its consistent sustained speeds and thermal control during long transfers, calling it a solid pick for video editors and photographers. The unit supports Thunderbolt 4/3 and USB4 with active cooling, making it ideal for power users on M1/M2 MacBooks and Windows laptops. However, Reddit users noted the fan noise under load and lack of encryption/RAID features may be drawbacks for enterprise users. Best for creative professionals who want Thunderbolt speeds without the premium cost, but those needing quiet operation or advanced features should consider alternatives.

Strengths

— Supports Thunderbolt 4/3 and USB4 with up to 40Gbps transfer speeds
— Active cooling system with fan and thermal pad ensures sustained performance under heavy load
— Tool-free installation for M.2 NVMe drives with support for 2280, 2260, 2242, and 2230 sizes

Watch-outs

— Fan is audible during sustained heavy use
— No hardware encryption or RAID capabilities
— Some early firmware polish needed for maximum compatibility with older USB ports

How they stack up

ACASIS USB4 40Gbps NVMe Enclosure

The ACASIS USB4 40Gbps NVMe Enclosure outperforms the ASUS ROG Strix Arion in terms of Thunderbolt 4/3 support and active cooling, making it ideal for creative professionals. However, it's less aesthetically pleasing than the OWC Express 1M2 and lacks hardware encryption, which the OWC offers. Compared to the Plugable USBC-NVME, it provides better performance and compatibility but at the cost of fan noise and a more complex installation process.

ORICO M2VG01-C3

While the ORICO M2VG01-C3 offers a transparent design and plug-and-play simplicity, it falls short of the ACASIS USB4 40Gbps NVMe Enclosure's active cooling and Thunderbolt 4/3 support, which are essential for sustained high-performance tasks. Unlike the ASUS ROG Strix Arion, it lacks RGB lighting and a rigid aluminum construction, making it less appealing to users who want premium features. Compared to the Sabrent Rocket Nano V2, it provides better portability but at the cost of performance and durability.
