I have had experience with other VTL's that use compression.You win space, but to keep your drives in streaming mode it sometimes becomes hard.For example , you have an LTO4 drive which requires 40 Mb/sec datafeed to keep in streaming mode.With Oracle or other databases, you can get really good compression ( 5:1 ) and higher,which will mean that you need a throughput of 200 Mb/sec single stream to keep your LTO going.If you do not get that,the drive will stop/start/stop/start ... which kills your tapedrive in the end.

The above was related to exporting to physical tape,so if you're not going to do that, you're fine 
Then you have to calculate a bit how much the space you gain costs vs the 10k for the compression.Some data compresses well,some nearly not,so it depends a little on your data if you would benefit.
