I want to hear your opinion about the safest way to store backups of data. Let's take 3 mediums -- external USB3 HD, USB flash drives and DVDs. I personally stick to Verbatim DVD +RW. The backup costs about twice cheaper than USB3 flash drive (per GB). Though it's a little bit more hassle with the discs... As per external USB3 HD's... First of all, it's a little bit of an investment upfront. More importantly, what kinda bothers me a little is the notion that after all, a hard disk is a hard disk. It has mechanical parts, vacuum inside, integrated electronics. Too many things can go wrong and magically you can wake up some not so beautiful morning and your disk is dead!
Let's not discuss SSD's here please. They're still a little beyond my budget.
