The image was for a external drive connected to a laptop through eSATA, will the results vary when the external drive was connected to a more powerful system or just the interface matters?

 
Solution
They represent different types of load, ie different file sizes. These can be useful when comparing drives for a particular application, or if you wanna get really techy you can compare drives with similar overall speeds for differences under different loads etc. The point is a good drive will do equally well with different types of load... unless it's optimised for a specific load of course. Basically for the majority of us we can just go with the big numbers
