This is probably a 'noob' question, but what would be the benefits of running 2 hard-drives over 1? I'm debating on getting 2 500GB drives or 1 1TB drive.

one of the raids could save files on both drives so if one dies your files are safe. another one gives you speed. or you could keep one for OS and another for files.

You're better off just buying one 1TB drive. You can run them in RAID 1 which will write your files to both drives, which will give you a back up in case one drive fails. But you'll only have 500GB of storage. Or some people choose run two drives in RAID 0 which writes half of your files to one drive and the other half to the other, so they can then be accessed simultaneously giving you faster load times. Although its debatable if the small performance increase you get is worth the money you have to pay for the extra drive. And since you're running two drives, you have an inherently higher risk of drive failure. And therefore a higher chance of losing your data.

There was no question about RAID, so why are you two addressing that?

Because there's no benefit of running two 500GB over a single 1TB drive unless you're using a RAID.

I think mentioning RAID was very valid to the OP's question as there are no other benefits of using two HDD's over just one.

Originally I had a 2nd HDD (the 500GB) as an easy upgrade to install programs/games on (my main HDD was an 160GB and getting crowded). Eventually I replaced the 160GB with 1TB, so the 500GB remained as a drive to back up files from my laptop such as music/documents.

But generally, A 1TB drive is fine, two drives aren't really necessary.

Actually the comments of RAID helped me out as I didnt know what it even was at the time. When I format my HDD will I have the option of what RAID setting to set it to? I decided to go with a SeaGate 1TB model, thanks for the help all. :)

you might; you might not. Many self/custom built computers will have RAID. most consumer pre-built computers (Dell, HP, etc) do not.

I still stick to the habit of having my OS on the main (SATA) hard drive while I keep a large permanent pagefile on the secondary hard drive (EIDE) only. Windows (from 3.1 to 7) always seemed to run smoother for me.

I also keep a lot of downloads/backups/virtualization stuff on the secondary drive just in case the main drive bites the dust.

With that setup, the rate of fragmentation on my main drive seems a lot slower.

If you only bought one drive than you can't set up a RAID. A RAID requires at least 2, 3, or 4 disks to operate, depending on the type of RAID.
