Danny,
I've used a Hyperdrive 70x with PM for most of the last year. I just got a space but haven't had a chance to use it yet. With the PD70x, the easiest way for me to use it was to set it to download the entire disk, and check for what it had previously downloaded and maintain the file structure.
I download the entire disk that way I make sure it checks all the folders and I don't screw up and forget one. Takes a little bit longer but I'd rather be safe.
I have it check what it has already downloaded (incremental ingest) so that way only downloads whats been added since the last download. I like to leave my data in as many places as possible in case of a hard drive crash. In this case it's a little silly, yes, but it makes me happy.
I have it maintain the file structure becauase I don't want to end up with one folder being 20gb because I had a busy day. That way it always keeps the folders at 1gb, which is my largest card size. It adds more, and unnecessary depth, to the folder structure, but it's not a big deal.
I also set it to open folders after ingest. This way I'm ready to select as soon it's done downloading.
I'd be happy to offer any other experiences I've had if you need suggestions. And personally, the combo works well, with the right settings.
