StarTech USB31CSAT3CB Overview

Get ultra-fast access to data by connecting a 2.5" SATA SSD/HDD to your laptop's USB-C port. Take advantage of the USB-C port on the latest MacBook, Chromebook Pixel or other laptop to get quick access to your external drive. This cable-style adapter lets you use the USB Type-C port to connect your laptop directly to a 2.5" solid-state drive or hard drive, and access it through ultra-fast USB 3.1 Gen. 2 (10Gbps). It's fast and easy to connect to your SATA drives, with no additional accessories required.
Ultra-portable with no external power required
You can quickly access your valuable data, wherever you go, using this cable-style adapter. It's USB powered, so there's no external adapter required, and features a compact, lightweight design that you can easily tuck into your laptop bag or carrying case.
Convenient drive access
The adapter cable lets you quickly swap HDDs or SSDs without having to install your drives into an enclosure. You can copy or retrieve data from a 2.5" SSD or HDD quickly. It gives you easy access to your drive for data migration, drive cloning and data backup applications, with the fast performance of USB 3.1 Gen 2.
Connect easily, with USB-C
The integrated, easy-to-use USB Type-C connector is small and reversible, which makes for easier insertions. You can connect the plug with either side facing up, which means less risk of damaging your ports, and less frustration.
Harness the speed of USB 3.1 Gen 2

Does not work with brand new Apple Mac Mini M2 Pro

Just purchased one of these on Amazon this week. Does not work with a brand new Apple Mac Mini M2 Pro. I have an older StarTech USB-A variant of this same adapter, and if I plug it in through a USB hub to the same Mac Mini M2 Pro, the same drive pops right up. Will be returning this USB-C one to Amazon this week, unfortunately.

How good or worthy is this one compared to the cable from AngerBird?
Asked by: Talha
Both manufactures are highly well known. BH #STUSB31CSAT3 is a special order item. While BH #ANCSATA isn't. They're both design to do the same thing. At this point, it would be your personal preference.
