I thought when the data is striped, the chunks are put on the HDs alternating but the definitions shown in the site shows it like this:
Scenario 2 -- data is striped across two drives. in this scenario, while data chunk x is being located, data chunk x+1 is being simultaneously seeked. For simplicity sake, suppose the overlap time is 5ms (50% of the original seek time). Thus, in this highly simplified example, the total access time is 30ms.
Chunk 1 is found off drive a - 10ms
Chunk 2 is found off drive b - 5ms
Chunk 3 is found off drive b - 5ms
Chunk 4 is found off drive b - 5ms
Chunk 5 is found off drive b - 5ms
What is the point if it keeps putting chunks on the same drive?
