As I understand, the worst thing you can do to your hardware and your disks is to power off. Shock to the power supply, motherboard components and the disks have to spin up again, which often times they can't do, but would keep spinning reliably for another couple of years if never powered down. So would it be best to keep a system like this up 24/7? How does life expectancy compare using home PC versus server PC? Are there hard drives out there that stop spinning on their own after a certain time if inactive? SSD's are getting much bigger now. Are they now considered more reliable, less reliable or not decided yet against spinning disks? Chris Bennett
