I use Samsung T5 2 TB with my MacBook Pro and Dell XPS. I also use Samsung T3 1 TB with PS4 Pro.
T3 with PS4 Pro definitely improves loading times on games like Witcher 3 and Batman Arkham Knight.
T5 keeps my Steam Library (both MacOS and Windows), Logic Pro X Sound Library, aircraft maintenance database of a work software and some ISO & setup files I keep with me for IT support. I also plan to use it as a cache drive with Final Cut Pro. Before, when I used mechanical hard drives, these processes were nigh impossible. Now, it provides a quite smooth experience which was not possible on the mechanical drives I used to have.
They are also quite small and easy to move around even when on use due to having no moving parts inside. I recommend these devices to anyone who could use similar to my use cases. For regular storage of documents, music, photos and videos, a compact 2.5" mechanical hard drive will do just fine as a much budget friendly price.
