How to choose an external drive?

Question

Hard disks

You need a hard drive to store photos.
Interested in what to look at and in general how to choose?
Should I buy 2 disks of 500GB or 1 for 1TB?
And you should generally consider ssd, the disk may not be used and lie for 2 years ..
Thanks for the answers

Answer 1

Basically, it doesn't matter.
Any disk that suits the capacity and price.

the disk can not be used and lie for 2 years.

When disconnected from power for a long time, SSDs tend to lose information, and it is better not to consider cold storage.
And in any case - if the data is important to you, do not forget about backups.
