"Will that constant powering up [and down] add wear and tear…?". No. I suppose my other option is buy a Sata switch, so I can actually turn off hard drives that are not being used. For example, after booting Windows and everything else, when the computer is idle. If the system doesn't need to access the hard drive for normal operations, then it's perfectly possible for it to boot from a HDD, take whatever preparatory steps may be necessary, and then allow the drive to spin down while working with data in RAM only, with the hard disk spinning up only very occasionally if indeed at all. ), But I got a very different answer from Steve Gibson, author of SpinRite, a venerable and highly-regarded hard drive maintenance program.

It would only spin up later, when issued an ATA command. Would running them all the time decrease longevity, and would the increased power demands make a big difference on the electricity bill (for say, 6 hard drives)?
