I'm looking for a 8TB (or more) Thunderbolt (version 2 preferred) storage for under $800. This would be for backup for a nMP (when it arrives some day). The two that I am considering so far are (#1) LaCie 2big 8TB and the (#2) WB My Book Thunderbolt Duo 8TB. The LaCie seem to be faster than the WB from what I have read in reviews. Does anyone use either of these ? Any positive or negative experiences with them ? I'm also curious about speed (what speeds are you seeing ?) and noise levels. Is there a drive not on my list I should be considering ?
