Actually, I want to buy the waterproof external hdd, and I think maybe I can try HD710M or HD710 Pro. The design of the HD710M Pro means it can offer protection against dust and water that goes beyond the highest-level IP68 standards. In particular, the external hdd HD710M Pro is waterproof to the point where it can withstand 60 minutes submerged at 2 meters, giving it water protection that exceeds IPX8.

HD710M, is the huge capacity for huge convenience. 

Storage capacities of up to 2TB and the high-speed USB 3.2 Gen 1 interface mean that you can store whatever you want, whenever you want, while on the go！The external hdd HD710M Pro differentiates itself from other storage solutions with its user-friendly waterproof cover.

HD710 Pro, beyond IP68 to withstand the unexpected.

ADATA external storage expertise results in a drive with total dust-tight protection and a submarine-like ability to survive water.

Lesser external drives keep trying to work even if they fall or encounter a shock, resulting in errors and bad sectors.
