External Hard Drives

  1. If you are doing much data transfer USB2 is VERY SLOW. If you have a newer computer you are best with USB3, eSata or Firewire. Controller cards can be added to older machines for any of these. I'm a photographer and have over 70,000 pictures on my computer. I have an SSD for my "C:" drive and four 2TB internal drives. For backup I have a pair of external USB3 3TB external drives and a 2TB external eSata drive. Not to mention a bunch of older USB2 1 TB drives. For reliability you are best off to leave these units turned off when not in use, most have no cooling fans and heat is what kills drives.

    Last, remember it is not a matter of if a hard drive fails, its when it fails. All drives will fail, its just a matter of when. So, whatever you get come up with a backup strategy and stick to it.

  2. With so many stories of hacking lately, I like the idea of keeping the sensitive stuff where I'm the only one with access. I keep some media files, school documents, etc on my dropbox, google drive, and such. I'm the only one with physical access the my hard drives, birth certificate, ss, etc. YMMV
     

  3. As archaic as the rule of 3 is, it's still valid.

    3 backups. 2 immediately accessible, one off site.

    When I was taught, it was long before cloud storage or the internet being able to field large files well.

    Generally it was tape backups, one in the server room, another in a safe somewhere else on-site, a third copy of it at another physical site location also in a safe.

    Nowadays, with how cheap storage media really is, you could have two usb hard drives and duplicate from one to the other.

    Keep the second one somewhere else safe - safety deposit box is a great solution.

    If you want long-term storage, then optical media (cd,dvd, blu-ray) is the only way to go. Non-magnetic, so won't be erased by magnets. Doesn't suffer the (roughly) ten year limit flash media does.

    As long as the cd is physically in good condition, what is on it is on it. Just keep them out of sunlight and excess heat, safe in a binder from being scratched, and they will last for a very, very long time. Don't write on them with a sharpie, use a real cd marker with acid-free ink.

    Yep, I actually had a WD 1TB fail. It was on my satellite dish receiver. When I had Dish Network, you could use an external HD to expand your DVR... sure enough the HD failed (under warranty) they replaced it, but I lost all my stuff.

    The replacement drive has worked fine, but I do not fully trust them, back important stuff stuff up in different places. Don't put all your eggs in one basket.
