Which HDDs should I buy for new gaming PC?

Hi guys,

I'm in the process of ordering the hardware for a new gaming pc build. I don't have the money for SSDs, so I am looking to order the ideal combination of HDDs at an affordable price (hopefully around $200 or less?).

My build is primarily for gaming and media playback (lots of 1080p .mkv movies) and consists of an intel i5-750 processor, an ati radeon hd 5850, and 4gb of g.skill ripjaw RAM. I will be running the 64-bit version of Windows 7 pro.

I am ordering an Asus motherboard that supports SATA 6Gb/s (listed below)

So here is my question for you guys: what would an ideal setup of HDDs be for my purposes? I would like at least 1TB of storage, and it's been recommended that I get two HDDs, one for the OS and programs and one for storage of media.

Also, I am tempted to get this 1TB western digital SATA 6.0 HDD, as I can save $30 if I combo it with the PSU I am planning on ordering.

In addition to recommendations for my HDD setup, thoughts on SATA 6.0 and the HDD listed above?

You can't go wrong with that drive, having 2 drives is always an advantage. But if you can't afford 2 now you can always add a second one later.

With that setup, I would go 2 (1TB) Seagate Barracuda 7200.12's in Raid 0. It would be wise to backup your (important) files frequently; although even in a Raid 0 the chance of either disk failing is less than .1%.
