This HD meets and exceeds my needs for external storage space. Holds tons of large files, transfer rates are fast with USB 3.0. No issues with this HD. I would highly recommend this to anyone needing extra storage outside of their internal pc storage. Back-up functions work well. 4 TB of storage space is amazing! 

Question: Does the laptop have an internal drive?
Answer: I would highly recommend this to anyone needing extra storage outside of their internal pc storage
