Silent NVMe Enclosure for Mobile Workflows
The Acasis 40Gbps NVMe SSD enclosure houses an M.2 drive in a fanless aluminium-fin chassis that dissipates heat without noise. An Intel JHL7440 controller provides USB4 and legacy USB 3.2/3.1/3.0 connectivity. Measured sequential transfers reach 2805 MB/s read and 2734 MB/s write with a Samsung 980 Pro on a MacBook. The pocket-sized shell suits recording studios, quiet offices and overnight backup routines.
Suits creators who need silent speed.
Video editors and photographers who move 10 GB files in seconds benefit from the 2700 MB/s real-world ceiling and zero acoustic signature. The enclosure also fits travellers who want a durable, pocketable drive. Systems restricted to USB 3.0 will see drastically lower throughput, so buyers on older ports should consider whether the performance drop is acceptable. No internal fan means no moving parts to fail.
The Intel JHL7440 controller decides peak throughput
This single chip enables the 40Gbps USB4 link and backward compatibility down to USB 3.0. If the host port supports USB4, the enclosure can sustain the advertised 2805/2734 MB/s figures; on slower ports the bottleneck shifts to the host interface. No other specification in the data alters that ceiling.

Questions about this item
What real-world transfer speed can I expect from the 40 Gbps rating when the enclosure is connected to a USB4 host?
The Intel JHL7440 controller delivers up to 2700 MB/s real-world read and write, with tested peaks of 2805 MB/s read and 2734 MB/s write using a Samsung 980 Pro on a MacBook.
Which USB standards does the USB4 interface actually support for backward compatibility?
The enclosure works with USB 3.2, USB 3.1 and USB 3.0 hosts, automatically negotiating the highest speed each port allows.
Does the aluminium-fin chassis need any extra mounting hardware or a specific M.2 length to fit inside?
The fanless finned enclosure accepts standard M.2 NVMe drives and requires no brackets, screws or additional mounting hardware beyond the drive itself.
