Hi Carl,
They can write at the same time if they have raid software. That's part of what raid is all about. It seems like most of the big storms hit at night. I like to hike in them when they hit in the day time.

Hey Bob,

This is a good list for information. I did not know a computer can write to two hard drives at the same time. Wow. It is a good day when one learns something new. :-)

If I were there and it was storming, I would be in bed asleep. I love to sleep during a storm.
:-)


Carl

Darn, another power out just as I was finishing this.
Let's try again. :O)

How in the world can "writing" to two different hard drives speed up the process? And the biggest concern is when a power surge, either lightening or otherwise, kills the machine and all what's in it. What then?

If the two hard drives are each on a separate channel, the data is split up and it can write/ read to two at the same time, or almost the same time. It's because you can only push so much data through each channel. Theoraticly this sounds good, but in reality, it sounds like you don't get that much of an improvement.
Well, when everything in the machine is dead, go buy another and start over. What else is there? :O) The only thing to do is move on with life.
