Need new External Backup Drive

[Starbrand]

I got OS, few art programs, and WoW/SC2 on the Samsung 128Gb SSD and everything else on the Seagate Barricuda 2TB HDD. Now my problem is, I can't backup to my current external anymore (Seagate 1TB External) due to size. So I would like to buy something bigger to last long OR possibly two externals to backup twice.

what do u guys think? was either thinking of these solutions:
1. Seagate Backup Plus 3TB usb3.0 External
2. Rosewill Enclosure w/fan + any suggested 3TB HDD.
3. or the Orico Dual-Bay Docking Station w/ possibly 2 new HDDs or 1.
4. OR any other suggestions?

Probably just whatever size Western Digital Elements would be fine.

You need to think to yourself "Do I want RAID for date security?". I would go for a dual bay raid ready one just incase you want to.
