Hi All,

I'd like to buy an external drive enclosure with drives to act as both primary storage and backup for an iMac. I will be using Carbon Copy Cloner software to backup the drives and would ideally like a 4 drive enclosure:

2TB drive 1: primary storage
2TB drive 2: copy of drive 1
2TB drive 3: 2nd copy of drive 1 - easily removable to be taken off site and periodically brought back to catch up.
2TB drive 4: bootable copy of main mac HD

Can you recommend a particular drive enclosure and drives? Can't be too expensive, but don't want to compromise on safety of data. The plan would be once the drives are full to remove them and store and then insert a new set of drives.

Can anyone offer advise?

Many Thanks
