So here's the situation. I got a new computer with a 500GB hard drive back in May 2008. I expected it to last two years. Well, it's been 21 months and I'm down to the last 24 GB of space. I'm out of room. I have to get a new primary hard drive.
Here's how I've been doing it. I sync Computer A with external backup hard drive B (500 GB), one-way transfer, easy. Now Computer A is down to 24 GB. Hard Drive B is down to 100 GB.
If I get a new external hard drive C, then what? How big should it be? Let's say I get another 500 GB hard drive (C). What happens when I fill up the last 100GB of hard drive B, and now I have about 400 GB of free space on C? Do I then get a hard drive D to back that up?
Another thing to consider now is whether the drive should have an external power supply or be one of those plug-and-play drives. Since I use LR2, I'm kind of reluctant to have to plug in a drive to get files online, and prefer to have them always online, if possible.
This has the possibility of getting really confusing. Can someone offer their story about how they manage multiple drives?
