MySQL 5.6 disk requirements

I'm confused on the requirements for hard drives in MySQL 5.6 when compared to 5.0.45. When running a sysbench on MySQL 5.0.45 the drives light up like a Christmas tree. When running the same exact test in 5.6, the drives are barely being used and I get a higher score(as expected from the upgrade). I did a test using a single drive and then 4 drives in RAID 0 to see what scores I get.

Single drive box:

Intel 3770K box w/ 32GB RAM
MySQL 5.6.00
1 x Cheetah 15K RPM
8 Cores in system
8 mysql threads
TPS = 5647
R/W Requests per second = 79067


RAID 0 (4 spindle) drive box:

Intel 3770K box w/ 32GB RAM
MySQL 5.6.00
4 x Cheetah 15K RPM - RAID 0 on Areca RAID card
8 Cores in system
8 mysql threads
TPS = 5698
R/W Requests per second = 79781



So my main question is, how did one drive do the same as 4 drives in RAID 0?
