To raptor or not to raptor

[Rehan]

I currently have 2 80Gb Hitachi drives in Raid 0. I am fed up with backing up on DVD's so have decided to get a cheap used 36Gb raptor (Thay have long warranties so no worries about it going wrong) to replace my Hitachis as the main drive.

1) How much faster is 1 36Gb raptor than 2 Hitachis in RAID 0?
Will Battlefield 2 load faster or slower?
Anyone got any relevant (simple) benchmarks?

2) What about the difference between 8Mb and 16Mb cache versions

3) How much louder is it?

Thanks

Thanks a lot. Looks like I will just get a cheapo drive to do regular backups on. A B-Grade one perhaps? or one on eBay which still has its warranty.
