I currently have 1 750 gb hard drive and a 750 gb hard as my backup (internal but encased as external). I am running out of space on the main drive and bought a new 1 TB hard drive. Should I use that as my backup and move the other 750 GB into the desktop or just install the 1 TB into the desktop?
I think the 1TB is faster but I wouldn't set either up as the OS drive - I'll just leave the current 750GB drive as the master/OS drive. My question is whether I will run out of backup space too quickly if I don't use the 1 TB drive as the backup drive.
Current OS Drive - 750 GB WD Caviar Black (95% full)
Current "Backup" - 750 GB WD Caviar Green 3.0Gb/s
You will really not see a difference between the 1TB and 750GB Blacks (specially on a SATA II controller). I don't think it will be worth the effort to reinstall everything for the new drive. I would just move everything you can to the new drive to free up space on the 750GB Black.
