My question now is which format I should use for my internal SSD drive on the iMac: HFS+, exfat or Fat32? Are there any performance differences? I used Fat32 on an external disk for my MBA and am not impressed that file sizes are limited to 4GB max.
My research suggests that with boot camp I should reserve 30GB, and possibly more if I also need the entire Photoshop range under windows. I Really want to make the switch to Mac OS, but will also install Windows as a backup. I will use 1-2 external 1TB SSD drives as I am very concerned about backups as a hobby photographer and rather spread my risk than have it all on a single drive. it will be a maxed out version, except that I up the drive to only 500GB but all SSD. I am about to purchase a new 27' iMac which will be my first full PC replacement.
