#182926 - HDD surge protector, what would it take? |
After helping someone recover data from a RAID array, I started thinking about all that precious data on my hard disks. I have a backup regime that I think is adequate, but it occured to me that an overvoltage protector on the 12V and 5V HDD supplies might be worth having. My reasoning is that the PSU is made for a staggeringly small amount of money that can't include a lot of niceties. An overvoltage condition can take out all your hard disks in one go, as well as your motherboard.
Having designed overvoltage crowbar protectors in the past, I know it's not that difficult if you know the limits you have to meet. Does anyone have any thoughts? |
