new hard drive setup

[bakes0310]

Right i want two hard drives one for putting OS and drivers on and the other purley for games.

This is what i was thinking:
Western Digital Raptor 74GB 10,000RPM SATA 16MB Cache- OS and drivers only

For the second hard drive i have no idea i want minimum of 160GB and and its got to be reliable so it will last a long time and if possible quite fast if thats important.

Cheers for the replys so this is what i have decided on then:

Western Digital Raptor 36GB WD360ADFD 10,000RPM SATA 16MB Cache- 36gb will be more than enough for the OS and drivers.

Seagate Barracuda 7200.10 320GB ST3320620AS SATA-II 16MB Cache- This is a nice size hard drive for my games.

Having no idea about hard drives this leads to my next questions:

1. the 36gb western digital and the 74gb western digital are exactly the same except for size and cost but are defianetly the same speed and quality?

2. Never heard of seagate are they good for having reliable products

3. whats the 16mb cache mean if i remember i had 8mb cache on my current hard drive will i notice anything?

Cheers in advance for replys
