Hi, I am about to purchase a mid 2011 iMac spec'd up by Apple with a 256gb SSD and a 1TB HD. If I use migration assistant to transfer data from my old iMac, which has over 256gb of data, will it offer me the choice of where to put stuff? For example, my iPhoto library is around 90-100GB; I'd like that to go on the HD. Alternatively, I could make a DIY fusion drive with the 2 drives and then do the migration. Would appreciate thoughts and feedback.
