After reading the postings about RAID, I am thinking to setup a RAID1 for my home PC to save the hassle of hard disk crashing. I am using the gigabyte motherboard (GA-8VM800M), any comments for using the onboard RAID controller (VIA VT8237R)? What are the considerations of using external RAID controller versus onboard one? After putting a surge adapter to the AC plug, my harddisk and power supply are behaving better. At least, the PS failed because of aging now. Any other cost effective measure for supply protection? Running cost of UPS is a concern as the PC is on 247. Thanks in advance.
