I sharpen as a final step using PS. One method I have found helpful is to make the background layer a "smart object" and then create a duplicate layer of the background. I use a hi-pass filter on linear light blend mode on that duplicate layer. I then add a layer mask, invert to black, and paint white over the areas to be sharpened. You can add as much or as little sharpening as you'd like by adjusting the opacity on the duplicate layer. Also, you can sharpen specific areas of the image and not necessarily the whole thing. Play around with it and you might find it adds depth and dimension without sharpening areas better left alone!

If someone gave me a Seagate, I wouldn't use it. Yes, I know many people have them and love them, but they have a reputation for a high failure rate. There is a class action suit against them for just that reason.

I now buy the HGST Ultrastar drive, 3 or 4TB, which is an enterprise drive, designed for 24/7 use. It has a 5-year warranty. Buy the drive and then buy an enclosure for it.

I use SyncBack SE for backing up.
