Hi fellow mac lovers,

 

My new Air/Thunderbolt system is great but I just noticed that USB transfer rates through the Thunderbolt Display are much slower!

 

Same disk drive, same cable, same file, same copy command:

 

USB thru    Thunderbolt: ~0.5 GB / minute

USB from MacBook Air:  ~2.0 GB / minute

 

Anyone else able to reproduce this phenomenon?

 

Thanks for checking,

William
