[Benchmarking] Directory for the best effort part

[Cédric Briançon]

Hi all,

the base raster data are in /benchmarking/data/raster. For the best 
effort part, I'd like to reprocess the whole data into another 
directory, with our own tile system. So I would like to know if I can 
create a directory like /benchmarking/data/raster_retiled. This 
directory will contain the same amount of data than the original one, 
meaning around 120Go more on the hard drive. It seems the hard drive has 
1.6To free.

Cheers,
Cédric.
