Well I hoped for more performance - just feels slow. In its defence I am running multiple streams of HD video at 50Mbs but I use it beside Lacie Two drive FW800 and there is not much between them in practice. Yet to try it with 4K files - we'll see Host machine is new Mac Pro.
Looks good - metal work good - foam base good. Sadly - internal sockets misaligned and upside down - have to force USB plugs in with too much pressure. I bought two and both exhibit the same faults and also to cap it all they both have a failed socket.
So - if you just want to look at it or feel it - fabulous... for anyone who regularly uses their kit has to be a pass.
