Finally! New OWC 4m2 Ultra M.2 Thunderbolt 5 enclosure

Just saw this from NAB…

OWC has finally updated their 4m2 M.2 enclosure to TB 5, so a perfect little cheap RAID enclosure for Macs.

I’m still rocking my original PCI3/TB3 version that I used with a trashcan Mac, zero problems other than replacing the fan.

Same. I’m going to replace the damn fan soon. But maybe I just go get these instead

I saw it at NAB. It’s nice. The guy even mentioned some people are using two of them together to get more speed (like different busses). I have no proof of that working. But it sounded neat, until I thought of my raid zero being on two different thunderbolt cords. One plug away from disaster.

We get 4500MB/s off a single nvme via tb5. I guess more is better but idk if I need the risk of raid 0 when non-raid already goes that fast. I guess it would be nice to be able to go larger than 8TB.

You’re probably right. I’m thinking about moving back to a Mac and have a quad of 2tb nvme’s that could be reused.

What single nvme TB5 enclosure are you using?

This one:

BIG CAVEAT: we’ve found running it off bus power alone is not stable and will lead to intermittent disconnects. We’re running off powered tb5 hubs now with great success, but they were annoying until we figured that out.

Here’s another similar option. I’ve had two of these Acasis drives on two flame/macs for over 8 months without any disconnects or other issues. It never throttles and includes an automatic silent fan when needed. It is inexpensive and true TB5. Acasis is also releasing a quad-NVME version that I’m looking into for future that includes a hub for pass-through TB.

I’ve experienced this disconnect issue as well. Thank you for the tip on the powered hub, I’m going to have to give that a try.

Just don’t use that owc software , just format them zfs and it’s much faster.
