    Lightweight and easy to use. Lots of storage--- better than most drives and seems to work well. Put bit locker on it, but as large as 4tb it took awhile to complete the encryption process. Well worth it.

    This SSD storage had 4TB and is very small so very portable. And with no “moving” parts should last longer & be more reliable.
