I'm looking for opinions for my drive layout for when I get my 3.33 6-core (with 12G or 24G of memory -- I haven't decided on that yet). Bay 1: 120GB ssd - Boot drive Bay 2: 2TB hdd Partition 1 - 1880GB - home dir, my apps, data, etc. Partition 2 - 120GB - scratch (no immediate plans) Bay 3: 2TB hdd Partition 1 - 120GB - bootable backup of bay 1 ssd Partition 2 - 1880GB - backup of bay 2/partition 1 Bay 4: unused - for future expansion -- see comment about Windows below External Drive - 2TB hdd - 2nd backup (same as internal bay 3) Partition 1 - 120GB - bootable backup of bay 1 ssd Partition 2 - 1880GB - backup of bay 2/partition 1 Note that I specifically partitioned bay 2 the way I did so that the bay 3 backup partition is the same size as my main bay 2 partition and can also backup the boot drive. Of course this backup boot doubles as an emergency boot drive if the ssd fails and/or if I have to undo a "renegade" installer. The external is a backup of the backup which is only on line if needed. The reason I wanted the ssd as the boot drive is for quicker boot times and app launch times. Indeed I'll probably also put my own login/startup items and frequently used apps (e.g., the browser) on the boot ssd. I prefer to not to have any raid setups. I don't think I need it. Eventually I may want to add Windows 7. But I'm undecided as to whether I should just stick in on distinct drive in bay 4 or split the 120 ssd into two 60GB partitions and stick OSX in one partition and Windows in the other 60. Whatever scheme I do for Windows can someone tell me if the various Mac disk copy utilities (like CCC) can back up a Windows partition? And which scheme would be better for Windows? So does anyone have opinions (the pro's and cons) on this arrangement?
