Hi Gaurav,
I have always worked with external WD drives for that purpose. In my opinion there is no drive that is SUPER reliable. Especially the external ones which can come up with issues if they are not safely removed after usage. (although you click on safely remove storage, i had issues with these drives in the past).
For most of my data which i want to access regularly, i went with Dropbox and got a subscription for 10 Euro per month.That gives me 1 TB of storage and easy access and synchronization options. I use about 400 GB on the cloud now.
For my other stuff (movies, etc...) i keep it on duplicated external drives because they are cheap. One is always connected to my WD media player on the TV, while the other is safely in the drawer. I use the windows program Synctoy to synchronize them with each-other, but there are other programs for that on different platforms.
Because SSD drives have no moving parts, they might be more reliable i would guess, see link below:

I can agree with their statement:
At least 3 copies of data.
On at least 2 different mediums.
At least one off-site.
