Reviewer: MGMacUser Location: Bellbrook OH Age: Over 65 Experience Level: Hobbiest Owned Product: less than a month
Rating: 5/5 Does what it says September 23, 2018 I bought the Helios 3 from OWC's garage sale. It arrived in it's retail box with everything included except 1 of the PCI slot covers (which was going to be removed to install the PCI card anyway). I purchased a M.2 NVMe PCIe card and installed a 500GB SSD in the card. Installing the PCIe card in the Helios was very easy. Once hooked to my iMac and powered up I cloned my OSX startup drive to the NVMe and restarted, selecting the NVMe as the startup drive. The iMac started in approximately 20 seconds. Now all my applications start almost instanteously and all programs that use the startup drive (cache/buffer/load additional extensions/etc.) are very fast. The Helios is built very sturdy. I put 4 additional feet on the side of the box and have it sitting on it's side (its taller now and not as wide). My only "beef" with the box is the fan noise. It's not real loud, but louder than the other thunderbolt 3 devices I have on my desktop. It would be nice to have an on/off switch on the box to shunt the fan noise when needed. I'd buy the box again.

I would recommend this item to a friend! Customer Videos:
