The OWC Aura Pro X2 has been great for me. Instead of doing this myself, I took my 2017 5K iMac to an Apple authorized service provider and had him install it for me. He removed the 24GB SSD that was part of the Fusion Drive assembly and replaced it with a 1TB Aura Pro. He left in the 1TB hard drive. The iMac now has 2TB of total storage. I am able to get 2GB/s transfer rates. It's a complicated to install upgrade but I believe that it was worth the cost.
