I have 5 1TB and 1 2TB hard drives that I use for storage and backup in addition to my boot drive. I am getting ready to install an SSD as my boot drive and it has been suggested that I bump up the chipset voltage a notch or two.
Is this a good idea?
I wouldn't touch it. It may pay to make sure your power supply can handle the 6 drives without straining.
You can calculate your power requirements at Antec by ticking off the components in your pc. http://www.antec.outervision.com/
