### ⭐⭐⭐⭐ Best value for Money External Hardisk
*by R***H on 25 May 2025*

Good Harddisk I bought at best price at the time. storage capacity is 320gb.Using it for backup of my marriage photos & Videos.Connectivity : Connected to my mobile via protronics Type A to type C Connector.Functionality: The Harddisk came with usb micro B to Type A cable. Transfer speed is not consistent.But never crossed 25MBps due to the fact that is a mechanica drive not a SSD and stayed Constant but sometimes dropped to 7-9MBps. Maybe it was slow to me because I used SSD in my Laptop.Conclusion : Go for it to Store your Memories backup in best price and easy to connect options. Weight is also light and easy to Carry.
