BACK UP YOUR FILES! You do not want to be the graduate student in the horror story who lost all of their data and notes due to a computer malfunction. Current online "cloud" storage also makes it extremely easy for you to work on the same files anywhere you want: at work, at home, at the library, at the coffee shop, etc. Cloud storage also enables you to work on multiple platforms, from computer to smartphone. As an example, with all of my files saved on a cloud storage system, I can read and take notes on my phone while on the bus and pick up immediately from where I stopped once I get to the office.
Important note: Check with your faculty advisor if there is any legal implications with storing your research data on cloud services, especially if your research is sponsored by the government or private enterprise, or otherwise deals with proprietary information or technology.
