I am wondering what real world difference i would notice in the different hard drive options offered by dell. My first choice was their 80GB model because i don't need a ton of space and it is cheapest, but it only has a 2MB cache. My other options are a 240 GB Raid 0 (2x120GB) configuration that i assume would be a lot faster, as it is much more expensive. My question is, for general internet browsing and for gaming (star wars galaxies, Everquest 2, Doom 3) how much of a difference would i actually notice between the two. I suppose a third option would be to get a 7200 RPM drive with an 8MB cache but i think the only one dell offers is a 200GB model which is nearly as much as the RAID 0 drives. Thanks for any opinions on how much of a noticable difference the better drives would make.
