Docking stations can accept either SATA or SSD drives, and are especially great if you have some old SATA drives laying around doing nothing. All you do is insert the drive in the slot, turn on the station and your drive pops up in explore and you can access it, run programs from it, etc. It gives you unlimited options for using older drives to store various data, programs, pictures, etc. You can also swap various drives by just turning off the station, insert the new drive, turn on the station and you are back in business. It works identically to a regular external drive, but gives you many more options. AND...it is far less expensive than buying several external drives! Notice the picture of the docking station in my link above; it is the item where I posted a picture of it. It is the black "box" underneath the HDD that is plugged into it, labeled #2.
With a dedicated external drive you can do the same thing but you are restricted to only that drive and whatever size it is with no options.
The Station gives you unlimited access to any drive you want. For example, I have one HD with all my family videos of the kids growing up that takes a full TB. I have a different drive that I use for only my system backups that I do twice monthly. I have another drive that I use for family vacation photos going back several years. I have another drive that I use only for storage of copies of my highly-valued programs, such as CorelDraw, Photoshop, Office programs, etc. If my DVD installation disks ever go bad or get damaged, I still have ISOs of them on my programs storage drive and I am safe.
As a side-thought, some of these drives I make duplicates of and store them in my bank safe deposit box. If a disaster happens to my home and I lose everything, at least I still have my Operating System, irreplaceable family videos and pictures, etc.
And so on...
