I'm about to set up a raid 5 storage array on ubuntu breezy 5.10 with MythTV 0.19 to act as my media backend / fileserver machine. It will run 24/7/365 (fingers crossed!).
My structure is as follows :
40Gb system disk
3x200Gb disks put together as one raid 5 device (md0)
My thinking is that since the raid array will be used only when it's recording TV / serving files on the home LAN, would I be able to power it down when not in use?
One problem that springs to mind is the hit on my power supply when all three drives start up at once if they've been sleeping (they're PATA).
