Thanks David, impressive results.

You (everyone) will also note that the first execution of your script will be a bit slower than 
subsequent executions, as the files are transferred from disk, and copies of them retained in faster 
cache memory.

Using an SSD-based disk will also be a bit faster than for a magnetic HDD, though the benefits of 
the disk cache (as a percentage) will be lower.
