Because if a DNS operator has decided to store traffic data, they will  
already have made the commitment to buy (or extend) some sort of NAS  
or SAN solution for that data. The incremental cost for adding disks  
will be lost in the noise, even if the traffic data is uncompressed.  
Shaving a few pennies on disk space seems silly. More so when the  
costs of decompression and recompression are considered when the data  
gets shoved through grep or something fancier to do traffic analysis  
or whatever.
