I specifically take issue with the moving parts section of this article. I have replaced many drives in my professional life, with most of them being HDDs. That being said, most of the drives I have used are HDDs. I have seen USB thumb drives fail at a much higher rate than HDDs, but since flash memory is not moving, it should be so much better, right? Wrong. As HDDs continue to increase to sizes that SDDs can only dream for in another decade, they have gotten better and better, but I can't say that flash memory's rate of failure has gotten any better, so would I rather pay less money for more disk space instead of a bit faster performance? Usually I would. Even Apple's new hybrid hard drives use both, so why would spinning HDDs be dead?

Also, onto optical media. I still trust those things at rest more than magnetic tape, HDDs or even flash memory. I know that I'll be able to spin one up 15 years later with the correct equipment and be 100% confident that the data will still be there. Would you trust your HDDs, flash-based devices, or magnetic tapes? I'll bet your entire backup on it.
