Hi,

Could you please give some further information about the runtime environment, regarding the following questions:

- On what kind of storage is the test data stored on? (ssd or hdd)
- Is it possible to write intermediate data to some place in the container and if yes how much data can be saved?

Thank you,  
Zsolt

The test data is on SSD. You can write intermediate data to the container within the [`submission` folder](https://www.drivendata.org/competitions/148/visiomel-melanoma/page/719/#what-to-submit), where your submission gets unzipped into. You can try this out with the smoke test submissions.
