Rebench: cutting through the myths of I/O performance
November 9, 2009
Seen via Adam: an article on Rebench, a tool used to benchmark hard drive performance.
We know that a random, uniform distribution workload with 512 byte block size results in 87 I/O operations per second on our rotational drive. Let’s try sequential reads:
