Hi All, So i finally took the plunge and ordered a non-fusion 27 imac 27". I do however have a lacie rugged ssd - thunderbolt which i was going to use as a primary drive and install the OS on there. Then i came across the following which shows how to combine an ssd and standard HD into a fusion drive: http://reviews.cnet.com/8301-13727_7-57550128-263/how-to-make-a-custom-corestorage-drive-in-os-x/ I am mainly going to use this computer for media (watching movies and browsing and the occasional office work). Should i go through the hassle of creating the fusion drive? Or should i just stick to using the external ssd as the primary drive?
