I bought a LaCie eSata hub to thunderbolt to use with my Mac Mini, but I'm very disappointed with the performance. Browsing with the finder on the connected HD (Western Digital My Book Studio II) is very slow and indexing thumbnails of pictures takes ages. I did a few speed tests and read and write performance is a bit under what I have when I connect the disk with Firewire 800! I mailed LaCie support but they say that the transfers speeds are normal, and it's probably the WD My Book that slows it down. (Suprise suprise blame the other devices, not their own.) Thing is: I used this exact disk with a PC for 2 years connected to a Windows PC with eSata and didn't experience any slowdowns. Has anybody else used the Lacie eSata hub on their macs and what was your opinion of the device?
