I wouldn’t expect there to be any benefit to using SSD since you’ll more likely be CPU constrained. Also spinning disks work well with backup jobs because of their sequential nature of writing to disks. Also you’re going to save a ton of $$/TB with HDD versus SSD. SSD would provide less heat, but I think the other benefits weigh in favor of the HDD as a better option.
