I decided recently to upgrade the storage in my Mac Pro. Currently it had 3 hard drives in it
- 320 GB – the one that came with the computer. This is little changed from when I got the computer as I immediately added a 500 GB and 750 GB to the machine as soon as I got it
- 750 GB – this is my startup volume, and has all the applications and documents on it. 90 GB free. It contained 1,803,033 files using 608.5 GB (653,331,116,032 Bytes).
- 1000 GB – this is my Time Machine volume, and has Time Machine backups going back 16 months to October 2008. 135 GB free. It contained 16,765,985 files using 787.6 GB (845,667,311,616 Bytes).
So for the upgrade – the plan was to add a 2 TB drive into the last empty drive bay in the Mac Pro to become the Time Machine volume, then clone the 750 GB drive to the 1000 GB drive, then use the 750 GB drive as a network backup volume perhaps.
