All of the software that you’ll need to complete class assignments is available in the Edit Bays in the Production Center (and on the computers in the upcoming computer lab).
If you’d like to purchase your own copies or subscriptions of the major software, some recommendations are:
Adobe offers discounted, student pricing for their subscriptions. Avid offers free versions of their software—the “First” editions. They’re fully functional, but have limitations. Resolve is fully-featured and available for free. You only really need to purchase a license for it, if you’re going to be exporting in 4K.
External hard drives can be inexpensive, but be aware that you really do get what you pay for. Most spinning, slim, portable hard drives are prone to failure. If you are in the habit of frequently backing up your content, this shouldn’t be a problem, though.
For the best performance, choose a hard drive that spins at 7200 RPM (5400 RPM hard drives are less expensive, but are slower). If you can afford it, go with an SSD, which has no moving parts, making it more reliable (with caveats) and much faster. SSD hard drives are more expensive than spinning hard drives for the same capacity, but aren’t prone to the same mechanical failures as their spinning counterparts. For example, an SSD can take a fall from a tabletop, and still work just fine. A fall like that can be the death knell of a spinning hard drive.
