I got this product a few days ago and I have been loving this product since then. It works very smooth and is slimmy in structure which is why it can fit in pockets. The size is very small. Transfer speed in this hard disc is nearly 120 to 200 MBPS which is very fast compared to other hard discs. It took me around 2 minutes to transfer 1 GB of file which is amazing and it is quite fast. It can also be supported to 3.0 USB port which is amazing for more faster transfers. I also tried using this hard disc connecting it to my oneplus 5 phone and it worked smoothly. I would suggest you to buy this product if you are looking for hard discs. Thanks for reading my review.
