Ahhh, the days when you could actually add things to laptops. It's probably good for me that I can't upgrade anything in my MacBook. I have always had a bad habit of mindlessly maxing things out (or at least using all the slots/ports). When I had my Lenovo T420, Micron had a sale on SSD's, so I purchased and installed both the mSATA and SATA drives that they offered. For $600 I now could carry every file I had, and didn't even need! Then one day, I saw a Wintec Expresscard SSD on a forum, for only $100! I then had another 256GB SSD to add to my laptop. I also stuck 16GB of RAM in that thing, since 8GB SO-DIMM's were so cheap at the time. Eventually I removed an SSD to use in another system and put a 2.5" 1TB HDD in there for more storage, and just ran the OS off the faster mSATA drives. In more recent times, you can add multiple drives to the workstation machines like the Lenovo P50, and I currently have a Lenovo T490 with two drives in it. However, you need to buy the right cables and drive adapter depending on if you want M.2 or 2.5" SATA drives, and only a small amount of M.2 SSD's will work in the other, shorter slot if you want dual drives. And yes, the T490 has a very un-used 32GB of RAM.
