well, this is not my area of expertise, but that's never stopped me before. I think the issue with SSD vs HDD for media storage has to do with what kind of sources you'll be working with and how complicated do you think your sequences will be. For example, if you're going to be working with a 4K multicamera shoot, an SSD would be advisable. HDD's are incredibly cheap so they're very useful as backup for the SSD. And proxy workflow will allow you greatly reduce your drive overhead, so that's another way of looking at it. And don't think a high dpi mouse will make a difference, bwdik.
