I very got the Lacie one as well and it works very well. There appears to be an issue when Daisy chained to the Caldigit Thunderbolt station, which manifests as computer won't wake up properly from sleep. I've been using the Lacie for about a year with zero hiccups so alone it works fine. Caldigit and LaCie are meant to be in conversation but Caldigit support have gone very quiet on me.
I've also got a cheap usb3 to e-sata adaptor which I use with my LG blu ray recorder (the Lacie has the wrong chipset to drive a burner). For £15 of Amazon its works very well.
GOOD POINT.....for just accessing an esata enclosure and copying files or just checking a backup I suppose a USB3 to esata would be just fine and most likely more compatible. Does the new Mac Pro have all USB3 ports?
We use hot swappable 3.5" drive trays in a JBOD enclosure with four bays. Each Mac gets one dedicated bay and we all have an esata card on our MacPros. But using a simple USB3 to esata could be a pain free way to get to those drives without compatibility issues with thunderboldt daisychaining.
