To the OP, YES YES YES!!! In my IT courses I have had regimented into me that data that is worth keeping should have 3-4 alternative backups! I keep a drive for standard windows backups, a 1tb drive redundancy backups of media, and then I keep a 2tb usb 3.0 drive for imaging/cloning my drive, and finally I have a "hotsite" hard drive that is cloned off of my current drive and the clone is updated weekly, so that in the event of total drive failure not only will I still have my media, I'll have a complete drive that I can just swap out the internal and just fly from there. In regards to drive failures, S.M.A.R.T values should warn you in 8/10 situations when your drive is drawing its final breaths. Watch them for anything major (a few reallocated count sectors, or a few values to spin retry count DOES NOT mean your drive is failing) and they should keep you safe. HDDs are less then a $1 per GB these days. On Amazon you can grab 80gb drive-in-enclosure models with a warranty for $30 and free shipping. there 160gb is $5 more and the 250gb $5 more then that. I have had one for about a year as a cheap quick swap for computers and its much more reliable and roomy then a flash drive not to mention faster. I have over 8tb of space in my computer setup and what I paid to get this vast amount of space is relative peanuts (about $600). Remember when the 32mb drives cost $1000? If you are holding out for SSD prices to come down, according to reports they're prices aren't falling for the next 10 years, and by then the SSD may already be surpassed.
