Review on 🚀 Upgrade Your Data Transfers with the NewerTech MAXPower eSATA 6G Pro PCIe 2.0 Controller Card – Reaching up to 500MB/s! by Aaron Hawk

I had an older Voyager USB, FireWire, eSata dock that I wanted to use with this card, but got it disconnected again and again after intensive use. I didn't know if it was the dock or the card so I decided to try a different dock (http://www.amazon.com/gp/product/B005UA3I72) and both the card and the dock work fine, none sleep / off problems. I would definitely recommend this card to anyone who has an older, non-USB3 Mac Pro and wants more speed from their external drives.
