Easy to Use Enclosure

It is an external hard drive enclosure! Very easy to use and I had it set up and my system building a Raid 0 on it within 30 minutes. I reserve the right to update this review since I've only had it up and running a few days.

Works well so far

I got this to add some storage to a mini pc I'm using as a homelab. It's connected via USB-C and has had no issues so far. The computer is running Debian 13 and I currently have two 10 TB WD Red Plus drives setup in RAID 1 via software and a third 3 TB drive by itself.

Good build but noisy

Noisy when i put my NAS HDD in the enclosure and same HDD is not making noise when connected using Feico adapter with similar transfer speeds. Other than that, good build, easy installation, compact design.
