I am looking for data, knowledge, know how, on ext. HD's such that I can pick between the top three best of the best (if that's even possible nowadays)for home backup use. I read an article at Tech Republic about SSD's and I have a Seagate Slim 500GB connected to my HP envy desktop but the long term data doesn't look to promising. I also read an article about Seagate is not using MTBF data and is or has created its own which is called AFR or Annualized Failure Rate. So I have to go to outside sites such as Tom's et. al. to try and find out which appears to be the best ext. HD available. Then I found BackBlaze site for 2013-15 has been and what's to be for this year but I can't find a link there so I can ask some questions about the figures they are using. If someone has read the data, then explain the per centages on what would be the top three so I can "maybe" figure out the Best of The Best. thanks ahead of time...
