Customer Reviews
As a Windows user I'm not fully-versed in Thunderbolt tech. Speeds vary, and without testing I often can't determine why. However, the device does deliver the speed promised, in a well-designed package that should endure long use.
I would recommend this product to a friend!
- Reviewer:imber
Thank you so much for sharing your fantastic review! We're thrilled to hear that the device is delivering the speeds promised and that you love the design! It's great to know that even as a Windows user, you're finding value in the Thunderbolt technology. We appreciate your feedback and are glad you’re enjoying your experience with our product!
Arrived quickly and well packaged. Plugged it in, opened the drive on my desktop and clicked the icon. Followed the instructions and within a minute I was up and running. Beautiful little palm sized drive that a tank could run over. This is my second one. Feels indestructible. Yeah baby!
I would recommend this product to a friend!
- Reviewer:MushyHornet-34619
Thank you so much for the awesome review! We’re thrilled to hear your drive arrived quickly and was so easy to set up. We love that you’re enjoying its rugged design—and we totally agree, it’s built like a tank! We appreciate your continued trust in OWC. Yeah baby! ?
Bought this about 6 months ago and now it doesn't work. At first it started to eject itself, or unmount itself at random times, from my Mac. Then, something went completely wrong. No it doesn't work. I plug it in, it won't mount properly, and disk repair always reports a severe error.
