Cloud backup is great for a one-man show when all you back up is a handful of files.
If you have more than a few employees and have to back up terabytes of data and have custom applications which require a day or two minimum to install and configure and data in multiple places, and downtime costs you hundreds, thousands, or more per hour, cloud backup services quickly become an epic fail - plus you need to worry about bandwidth caps with crappy ISPs.
Other backup solutions become more important - for low-budget IT a handful of large external hard drives swapped out daily and taken off-site is a workable (if not ideal) solution, but the best solution is still a tape drive - and replace the tapes after a few rotations. Remember when downtime costs you significant money, having full backups with a rapid restore times becomes critical.
Say you have an 8TB drive with 6 platters - the option could be to pair up the platters and write alternate bytes to each, doubling sustained read and write
That would require the head to be right over both tracks at the right moment. I'm not sure the heads are physically aligned that precisely. Or are you suggesting to separate the head assemblies for the top 3 and bottom 3 platters and do RAID 0 in a box?
"Specifically prohibiting a discussion of the scientific process is a recipe for educational chaos. To begin with, it leaves the knowledge the kids will still receive—the things we have learned through science—completely unmoored from any indication of how that knowledge was generated or whether it's likely to be reliable. The scientific process is also useful in that it can help people understand the world around them and the information they're bombarded with; it can also help people assess the reliability of various sources of information.""

Would it be trivial to design a drive that can be switched into a double-speed half-capacity mode?
High RPM drives tend to have smaller capacity if I remember correctly, and any drive can be short stroked to save on seek time.
