Hello everyone, I'm here seeking your help picking a good external hard disk for my PC. I have a few options in mind but I have a few doubts and questions.

Well I'm looking something like 3-5TB of storage. I would probably keep it connected to my desktop most of the time. But I would also like it to be portable in case I need to carry it. That's why I want external rather than internal. I am also in dilemma whether I should buy one 4 tb hard disk or two 2tb ones just in case not to put all my eggs on one basket.

I have a Sandisk SSD 500gb for my personal sensitive data. I need this to store my ever expanding music and other media files. Full HD Movies and shows and Flac audio mostly. So I also need it to be hooked up to my computer most of the time. I also like it to be compatible with Android TVs if I decide to take it to my dad's house and hook it up when I visit.

I am looking for fast data transfer and durability of the hard disk. I have a few within my budget.

Seagate One Touch 5TB

Seagate Expansion 4 TB

Western Digital Elements 4TB

WD My Passport 5TB

WD My Book 4TB
