During September purchase of an OWC 14-Port Thunderbolt Dock, OWCTB3DK14PSG, to use with my MacBook M3 and a ThunderBay 4 Mini, OWCTB4MJB000, for long-term and safe storage my 300+ ripped DVD movie collection (among other things, backups etc…) My knowledge of Thunderbolt connectors and drive enclosures was very limited. So a considerable amount of time was spent on the OWC website researching both. What I did grasp, along with my budget and storage needs, led me to the ThunderBay 4 Mini. After looking at the photos and watching the video on its product page, I decided to purchase it. I’ve just recently procured the SATA SSD drives for the enclosure, installed them to begin transferring my DVD collection only to find that the Thunderbolt connectors and cable that came with my ThunderBay 4 Mini are not compatible with my new Thunderbolt 14 Dock or MacBook Pro. They certainly weren’t the connectors in the ThunderBay 4 Mini video I watched on its product page. I’m disappointed to learn the ports on my new ThunderBay 4 Mini are not the Thunderbolt C ports shown in the video but older technology Thunderbolt ports, known to me as Apple display ports. To use my new ThunderBay I’ll need to purchase two adapters, although the website is unclear so I’m not sure if I need the ones that are $47.88 each or $64.99 each. I purchased a new drive bay with old technology and now have to spend an additional $100 to $150 for adapters because the information on the OWC website is unclear. This was a bad purchase so I’m forced to look for a different enclosure and take the loss. I was accustomed to better from OWC.

This unit works fine, but beware connectivity hassles. Unless you're quite familiar with Thunderbolt form factors, you may not realize that Thunderbolt 2 cables are physically incompatible with later versions of Thunderbolt. You will almost certainly need a Thunderbolt 2 -> 3 (USB-C) adapter, which will cost you about $50 from Apple. It's not clear to me why OWC is selling units with this connection type, as Thunderbolt 3 came out in 2016, but here we are.
I would recommend this product to a friend!

It's true that Thunderbolt 2 and Thunderbolt 3 have different connections, and we always recommend checking compatibility before purchasing. Your feedback is invaluable, and it helps us improve the experience for all our customers! Happy computing!
horrible. I can't connect it to your dock. I have ordered adapters and cables, but nothing connects. I can't connect to your my new Mac mini. It was a waste of money.
