ACASIS USB4 40Gbps NVMe Enclosure

4.4

1 source$75.99as of Aug 1

The ACASIS USB4 40Gbps NVMe enclosure is an aluminium single-drive M.2 case built around an ASMedia ASM2464PD bridge, with an active fan on top of a shell that already works as a heatsink. BestChoices lists it in its Acasis 40Gbps NVMe enclosure comparison. The draw is a 40Gbps path on hosts that support USB4, tool-free installation and temperatures well below what plastic enclosures reach; the costs are an audible fan under load, no encryption and no RAID.

Strengths

— Supports Thunderbolt 4/3 and USB4 for up to 40Gbps connection speed with consistent sustained throughput under long transfers
— Active cooling fan and thermal pad provide excellent temperature control during high-load operations
— Easy tool-free installation with click-fit 2280 NVMe drive insertion and included mounting screws

Watch-outs

— Fan is audible under sustained heavy load which may be disruptive in quiet environments
— No hardware encryption or RAID options—single-drive use only
— Some early firmware polish needed for maximum compatibility with older USB ports

Ranked #5 in Best External SSD Enclosures

ORICO M2VG01-C3

4.0

1 source$40as of Jul 1

USB 4.0 NVMe speed on a budget is the ORICO M2VG01-C3's angle, wrapped in a transparent shell that shows off the drive inside. PCWorld praised the easy installation and the speed while warning that the snap-together construction can come apart by accident. The heatsink runs hot under heavy use, which matters for long workloads. As a cheap way to add external NVMe storage it works; power users who want durability should look at alternatives like the Fledging Shell. Casual users who value portability and cost-effectiveness over long-term reliability are the fit.

Strengths

— Fast performance with USB 4.0 interface delivering up to 40Gbps transfer speeds
— Transparent design allows visibility of internal NVMe SSD for tech enthusiasts
— Simple plug-and-play installation with no driver required

Watch-outs

— Snap-together design may accidentally disassemble when mixed with other items
— Heatsink becomes uncomfortably hot during sustained heavy usage
— Not as premium or durable as higher-end competitors like Fledging Shell

How they stack up

ACASIS USB4 40Gbps NVMe Enclosure

Against the Samsung X5, the ACASIS lets the buyer choose the drive rather than paying for a bundled one, and against the ORICO Thunderbolt 3 enclosure it adds USB4 and Thunderbolt 4 support. The Sabrent Rocket Nano TB4 is more compact with similar thermals but usually costs more, and the ASUS ROG Strix Arion is smaller, cheaper and considerably slower.

ORICO M2VG01-C3

The ORICO M2VG01-C3 is more affordable and portable than the ASUS ROG Strix Arion, but it lacks the premium build quality and thermal management of the ACASIS TBU405 Air, which includes an active cooling fan. While the Sabrent Rocket Nano V2 offers a smaller footprint, the ORICO's USB 4.0 interface provides faster speeds, though its heatsink becomes uncomfortably hot during sustained use. Compared to the Plugable USBC-NVME, the ORICO offers a transparent design for tech enthusiasts, but lacks the multi-M.2 support and tool-free installation of the Plugable model.
