HardDrive Options
 

I'm running out of space on my machine at home ~20gb left. I use this computer only for games/music. It was a 160gb hd I bought when I first built this computer about a year ago it was on a budget so I went cheap. I only spent $380 in total and got 4gb ddr2 800 GSkill PI black ram, radeon 4890, amd 6000+ 3Ghz cpu and a 600watt psu. I think this guy is my current drive Newegg.com - Western Digital Caviar Blue WD1600AAJS 160GB 7200 RPM 8MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive I got it on sale for around half that.

Anyway I'm considering Newegg.com - Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
only $50 for a 7200rpm multiplatter 1TB Now here's the question should I keep the 160gb drive as an Os drive and run the 1tb for Storage or run a single solution with just the 1Tb drive. Keeping my current drive and running both will involve a lot less work as I won't have to reinstall everything but it might be a tight fit to add another drive with the 4890 in there. Just going with the single drive would be a simpler solution and starting from a fresh format is always good but starting completely from scratch is always more work. Just to be clear there is nothing on the computer I don't want to lose save my music which is already backed up in multiple places.

I'm not really sure which direction I want to go any thoughts?

I've always kept my primary and just added storage drives unless I have some other reason to reinstall.

I always reload the OS on the newer (faster) hard drive and keep the data on the old drive and copy it to the new drive, so it's in 2 places...

I just bought 4 x 500GB Seagate SATA hard drives for $60 each and a WD 2TB drive (Caviar, Black) for $165. Hard drives are cheap, but they tend to fail...

The only difference between the two drives is the cache.. 8 for the old, 32 for the new. RPM's are the same. If you are happy with the overall speed of the pc now, I don't think I'd go through the hassle of reloading the OS to the new drive. Do as HD suggested and add it as a secondary storage drive and also dump any music, pics, vids from the 160 to it.

2 of the 1tb drives as a raid-1 setup for storage, use the 160gb as OS
