Hi everyone! We recently had a Mac mini server hosting 27 iMacs which just got really slow and we can no longer stand it. We are going to buy one of the Mac Pro severs (no trashcans here) and we need to have a certain setup. The Mini had a 256GB SSD for the OS and a 6TB external (which was in RAID1 so there was really 3TB space). So what would be the best way to have a 1TB drive for the OS and a 2TB drive for student data? Would it be best to order 2x 1TB drives and 2x 2TB drives and RAID1 them? My concern is disc access and write speed. Thanks!
