Installing a Driver for RAID
I agree with you Ken.
A UPS carries a higher necessity (to me); as you mentioned, power spikes, brown outs, surges are a more of a threat to your data and equipment. -- Don Vancouver, USA "Ken Blake, MVP" wrote in message ...

Yes, but it's important to realize that a UPS is unlikely to be of any help if a surge is caused by a nearby lightning strike. The only real protection against that is disconnection of the power and internet connections when thunderstorms are around. "Ken Blake, MVP" wrote in message ...
