Hey All, I've read many threads on how to configure drives but since my budget is low right now, I have to make the best with what I have. Here is my setup currently: Tray1: OEM 1TB WD Black (Raid0 with Tray 2 as 2TB) Tray2: 1TB WD Black (Raid0 with Tray 1 as 2TB) Tray3: 1TB WD Green (Scratch) Tray 4: None External: 2TB Hitachi 7K2000 as Time Machine (But have yet to set this up) Additional HDDs used as manual backups (but can change them if I can come up with a better and efficient backup scheme): Backup1: 1.5TB Seagate Backup2: 320GB WD HDD (From old 2007 iMac) I read that it may be better to partition tray 1 and 2 to multiple partitions and have the primary partition be the boot and other as data such as content like photos, music...Also I'd like to have at least one HDD as a monthly manual bootable backup to stick in the safe deposit box. This computer will be used for both my wife's home graphics designs/wedding business as well as for personal use. Anyone give me additional help. Since I just received this computer a week ago, I have yet to fully set it up. I would appreciate all the help of you folks. Thank you in advance!
