Hi
I have a similar concern. About to buy my first imac - the top end of the i5 of the 27". I'm also looking at the fusion drive, particularly for editing that I want to get my teeth into.
I'm looking to start with imovie.
My concerns with fusion drive (FD) for editing are thus:
1) The FD will only have 4G available when importing files (after your system has > 128gb on it). So if I'm importing more than 4G of data then some will go to FD and remainder on HDD. What's the (potential) impact there when importing and editing. I'm hoping by the time you get to the editing perhaps the footage will all be back on to the FD if files get moved around.
2) the imac MOVES files/folders/blocks around and doesn't copy. Should that be a concern to me/us?
Any input and considerations here would be much appreciated. I'm no expert in this stuff but I have done a lot of reading on this and even a music editing guy that i spoke to at an apple store (employee) is not too enthused (yet) by the FD.
Ps this is a great and thorough article to sus out if you haven't already:

Thanks again in advance for any ideas. I'll guess we'll know more with time as it also appears all reviews on the imac have been done on imacs with the FD and in the 27" ones, only on the i7.
Had anyone seen benchmark figures on the 27" i5?
