Well...one thing I learned from my Win 95 days...more hard drives, more partitions, and more RAM...are better than miniscule amounts of RAM, one hard drive and one partition.
So, I would never suggest to anyone to buy a 1TB hard drive...unless he/she had terrific amounts of files to the extent that they needed multiple 1TB hard drives.
The reality is that a hard drive can crap out anytime. If all your eggs are in that basket and it craps out..."boo hoo, what do I do now?" will be the end result.
Not to mention things like doing file transfers on partitions on the same drive...is slower than doing disk-to-disk transfers of files.
I prefer to employ a number of hard drives (3 500GB SATA drives and 4 250GB PATA drives on hand along with a couple with lesser capacities for my 2 systems) rather than use one big drive/partition or one drive with multiple partitions.
I have a ton of .mpg files and several backups which help me to put that space to good use, along with archived .mp3 files and graphics files. I'll have more in the future, I suppose...but I believe 500GB (approx cost of $99 yesterday) is the largest size drive I would suggest for the average user at home (with interests/files similar to mine).
I like splitting/sharing that risk factor.
FWIW: Music files are nowhere near as large as video files. Think video for the largest size files that you will ever have.
And then you decide...
PS: I don't use a USB or firewire connection...I just have a case that's large enough to accommodate the PATA/SATA direct connection drives which I can fit. Connecting directly to the motherboard is much faster than either USB or firewire external connections.
