I recently made a RAID1 array in my computer to backup some of the most important data. Only after a while I realized that my power supply is starting to get old as it is 4 years now and it is not a brand name one, and that in the event of it´s failure there is a high chance of getting nasty voltages on either the power cable or the sata cable that might kill both disks. I don´t mind about the motherboard or the system disk or other things, but I want to make sure my backup data stays ok.
So I thought I could make a surge protector for both connectors. I found this note from Bourns regarding surge protection, but it doesn´t tell much, just shows their parts. Right now I am pondering two ideas, I can either add TVS protection at the power supply, or I could make a sata plugin board just for the hard disks.
What would you choose? I think that the inductance of the long wires might help the sata board in case of failure, and also it doesn´t require modifying the psu so that it could possibly become an open hardware project if I can source some reasonably cheap and easily obtainable parts for it.
What do you think?
