I just etched a high resolution 50MB image on datacoin testnet variable storage (DTC-TV) from my home in Long Beach CA.  

The bitfossil realtime indexer picked it up in good ole moorhead MN and rebuilt it without issue. <3

This is now the largest file etched with http://Apertus.io that i am aware of. <3

The cost appears to be about 4.55 DTC per 90K  at a pretty consistent rate of around 250K per minute  
It took  3 hrs and 25 minutes to complete.

I was seeing a lot of unconfirmed ? transactions but they appear to eventually clean themselves up.  

Thanks for your time.
